Russell’s Later Metaphysics and Science

This volume is part of the “MINNESOTA STUDIES IN THE PHILOSOPHY OF SCIENCE” series, specifically Volume XII, focusing on Bertrand Russell’s Metaphysics and Epistemology. The volume itself evolved from a conference held at the Minnesota Center for Philosophy of Science. The aim of the volume is to draw attention to Russell’s later metaphysics and epistemology, which is understood to include his ontology, theory of knowledge, and philosophy of science. While Russell’s early work in philosophy of science is well-understood, his later work, which is presented as a development of the earlier phases, has been less understood, with the exception of his pre-analytic phase.

Russell’s philosophy of science is notably addressed in his works such as The Analysis of Matter (1927) and Human Knowledge: Its Scope and Limits (1948). During his middle analytic period (1919-27), Russell applied his analysis to physics and extended it to the philosophy of science. He hoped this work would be acceptable to empiricist perspectives and contemporary physics and psychology. In his late analytic period (1928-59), major problems in epistemology and philosophy of science were addressed in An Inquiry into Meaning and Truth and Human Knowledge. One group of essays in the volume specifically deals with Russell’s philosophy of science and metaphysics, examining his analysis of instants in terms of events, his treatment of causality, and his lifelong commitment to science and its philosophy.

Kenneth Blackwell’s “Portrait of a Philosopher of Science” highlights Russell’s dedication to science. Blackwell notes that Russell’s “devotion to science was quasi-religious,” stemming from a deep need for certainty and potentially serving as a substitute for his lost adolescent religiosity. Russell’s later writings on science express this sentiment, stating that science, along with religion, art, and love, belongs with the pursuit of the beatific vision and the Promethean madness that drives great individuals. He suggests that the ultimate value of human life might be found in this pursuit, viewing it as religious rather than political or moral. Russell suggests that scientists are seekers after knowledge, driven by a desire to understand the object of their pursuit rather than seeking power or manipulation. He claims that scientists and poets engage in an “expansion of the ego,” moving towards a God-like perception of the universe, and suggests that Russell’s focus on science and its philosophy is metaphysically, even religiously, grounded, viewing the aim of scientific knowledge as a mystical union of the ego with the whole universe.

The concept of structure in The Analysis of Matter, a significant work in Russell’s philosophy of science, is explored. This book marks a step in Russell’s rejection of phenomenalism and the development of a form of Lockean Representationalism. The core claim of The Analysis of Matter is that knowledge of the external world is purely structural. This thesis is based on the idea that we are not “directly acquainted” with physical objects, and our knowledge of physical properties and relations is derived from structural knowledge. Whatever is inferred from perceptions is only structure that can be validly inferred, and this structure is what can be expressed by mathematical logic.

Within this framework, the distinction between structure and quality is crucial. External world events possess both structure and qualities, while perceived events are considered more fundamental than their qualities. Knowledge of external events allows us to know their structural properties but not their qualities. The philosophy of physics, according to this view, falls within the scope of this claim, implying that physical theories provide knowledge of structure alone. Russell’s perspective here is seen to have affinities with Ernst Mach’s Analysis of Sensations and Russell’s own 1914 external world program. Entities in this context are described as not experienceable, knowable, or even picturable, sometimes called “transcendent” entities. This transcendence, however, is presented as not obstructing our knowledge of content, as properties related to purely formal or structural properties are knowable, unlike intuitive qualities.

Newman’s objection regarding the triviality of structure is discussed in relation to Russell’s structural realism. Newman argued that if knowledge of the external world is limited to its structure, this knowledge becomes trivial. His point was that whether the world exhibits certain structural properties is a matter to be discovered, not merely stipulated. The difficulty with this view lies in the claim that only structure is known. This criticism suggests that despite Russell’s intentions, his structuralism might collapse into phenomenalism. If assertions about unperceived events are trivially true based on logic and empirical assumptions, and if statements about the external world are reducible to statements about perception, then phenomenalism is a guaranteed consequence if Russell’s view is accepted. This implies that phenomenalism is the single ontological assumption regarding the cardinality of the external world, and Russell’s structuralism is seen to guarantee its truth.

The sources highlight that Russell’s work in the philosophy of science is deeply intertwined with his metaphysics and epistemology, particularly concerning the nature of the external world, perception, and the role of structure in knowledge. His dedication to science is presented as a significant aspect of his philosophical pursuits.

Russell’s Evolving Concept of Sense-Data

Based on the sources provided and our conversation history, Bertrand Russell’s concept of sense-data is a central, though evolving, element of his epistemology.

In Russell’s early theories of knowledge, particularly in The Problems of Philosophy, sense-data are presented as the ultimate data of empirical knowledge. They are described as the completely certain, immediate, and precise data of experience upon which all other empirical knowledge is built. Russell argued that we are directly aware of sense-data without inference, and all other empirical truths are derived from this direct acquaintance by either deduction or induction. Sense-data are identified as the “things that are immediately known in sensation,” such as colours, sounds, smells, hardnesses, and roughnesses. He distinguished these from “sensation” itself, which is the experience of being immediately aware of sense-data. In this early view, sense-data were held to be absolutely certain, indubitable, infallible, immediate, precise, and self-evident. Russell suggested that when looking at a table, the brown colour is something quite certain.

However, Russell’s views on sense-data underwent a significant change, which he described as a “very important change” by 1921 in My Philosophical Development. In The Analysis of Mind (1921), Russell explicitly abandoned the term “sense-data”. His earlier view was that sensation was a fundamentally relational occurrence where a subject is “aware” of an object, using the concept of “acquaintance” to describe this relation. Later, he came to believe that the idea of a subject in this relation was a “mere echo”. While Russell abandoned the term, the extent to which he abandoned the underlying concept is a subject of debate among commentators. Some argue he did not entirely give up the concept in its original form, while others believe he virtually retained it.

In his later works, such as An Inquiry into Meaning and Truth (IMT) and Human Knowledge: Its Scope and Limits (HK), Russell’s epistemology continued to grapple with the foundational role of immediate experience. The concept of “data” in these later works appears to fulfill a role similar to that of sense-data, referring to propositions or statements that are known without inference. These data are considered to have some degree of independent credibility. Russell also introduces the concept of the “sensational core” of perceptual experiences in his later theory. This “sensational core” is the part of experience most causally dependent on the external stimulus and is seen as what remains after removing the inevitable inferences and unconscious influences that surround perception.

Russell’s later view in IMT and HK distinguishes between data and inference. Beliefs about things of which we are aware without inference, including those involved in “direct sensible knowledge” or “sensible fact,” do not require inference. Data in HK are sometimes described as “private” to the subject. Russell also distinguishes between “momentarily noticed” facts (data) and “remembered facts”. The idea of a “pure datum” is presented as an ideal to be approached asymptotically, suggesting the difficulty in isolating the immediate, non-inferential component of perception. These datum statements are supposed to be “purer” (less inferential and theory-laden) than those in ordinary language.

Despite the shift in terminology and the evolution of his views, the core idea of immediate, non-inferential knowledge derived from experience remained important in Russell’s epistemology. While in his early phase sense-data were seen as infallible, Savage questions this infallibility in the sources, suggesting that judgments based on sensation can be fallible. The process of deriving knowledge from sense-data or the “sensational core” often involves analysis, particularly in Principia Mathematica and later works, where complex entities are analyzed into their constituents.

In summary, Russell’s engagement with the concept of sense-data evolved significantly throughout his career. Starting as the bedrock of his early foundationalist epistemology, defined by their certainty and immediacy, the term was later abandoned, but the underlying idea of non-inferential data derived from immediate experience persisted in concepts like “data” and the “sensational core” in his later works. The question of the infallibility and accessibility of such “pure” data remained a complex issue in his philosophy of knowledge.

Bertrand Russell’s Evolving Theory of Knowledge

Bertrand Russell’s theory of knowledge is a central and evolving component of his philosophy, deeply intertwined with his metaphysics and logic. Traditionally, it began with a foundationalist approach to empirical knowledge, asserting that all such knowledge is built upon a base of immediately known, completely certain data.

In his early work, particularly The Problems of Philosophy, Russell posited sense-data as these fundamental data of empirical knowledge. Sense-data are described as the “things that are immediately known in sensation,” such as colors, sounds, smells, hardnesses, and roughnesses. He argued that we are directly aware of sense-data without inference, a relationship he termed “acquaintance”. This early view held sense-data to be absolutely certain, indubitable, infallible, immediate, precise, and self-evident. All other empirical truths were believed to be derived from this direct acquaintance through deduction or induction. He distinguished sense-data from the sensation itself, which is the experience of being aware of the sense-data.

However, Russell’s views on sense-data underwent a significant transformation, which he described as a “very important change” in My Philosophical Development. By 1921, in The Analysis of Mind, he explicitly abandoned the term “sense-data”. His earlier concept of sensation as a relational occurrence where a subject is “aware” of an object evolved as he came to believe the idea of a subject was a “mere echo”. While the term was abandoned, commentators debate the extent to which the underlying concept was retained. Some argue he held onto the concept in virtually its original form, while others believe he virtually abandoned it.

In later works like An Inquiry into Meaning and Truth (IMT) and Human Knowledge: Its Scope and Limits (HK), Russell continued to address the role of immediate experience, employing the concept of “data”. These data, often understood as propositions or statements, are those believed without inference and possess some degree of independent credibility. Russell introduced the notion of the “sensational core” of perceptual experiences, identifying it as the part of experience most directly caused by the external stimulus, remaining after the removal of inferences and unconscious influences. The idea of a “pure datum” is presented as an ideal to be asymptotically approached, highlighting the difficulty in isolating the immediate, non-inferential element of perception.

Another crucial aspect of Russell’s theory of knowledge is the distinction between knowledge by acquaintance and knowledge by description. While we have direct acquaintance with sense-data and possibly universals, our knowledge of most physical objects and events is indirect, acquired through descriptions based on our acquaintance with sense-data. This process of deriving knowledge from immediate data often involves analysis. Russell’s philosophical method often involves analyzing complex entities or propositions into their simpler constituents. This analytical approach is evident in his logical atomism and is crucial for understanding how knowledge of the external world, particularly its structure, is derived from perceived data.

Russell also grappled with the problem of inductive inference, acknowledging the need for principles or postulates to justify non-demonstrative inference beyond immediate data. He attempted to formulate such postulates to bridge the gap between perceived data and knowledge of the unperceived world.

Furthermore, in his later work, Russell explored the role of indexicals (“I,” “this,” “here,” “now”) in connecting the private world of immediate experience to the public world of scientific knowledge. Indexicals were seen as crucial for linking subjective sensory awareness to objective spatial and temporal locations and, subsequently, to the world described by science.

Overall, Russell’s theory of knowledge evolved from a strict foundationalism based on the certainty of sense-data and acquaintance to a more nuanced view involving “data” and the “sensational core,” while retaining the importance of analysis and grappling with the inferential gap between immediate experience and knowledge of the external, scientific world. His epistemology is fundamentally shaped by his commitment to logical analysis and his deep respect for scientific inquiry.

Russell’s Logical Atomism: Simples, Facts, and Analysis

Bertrand Russell’s Logical Atomism is a significant aspect of his philosophy, particularly in his metaphysics and epistemology. It is closely linked to his work in logic, such as Principia Mathematica. Logical Atomism proposes that the world is ultimately composed of simple, ultimate entities (atoms) and that complex things and facts can be analyzed or reduced to these basic constituents and their relations. This metaphysical view is mirrored in a corresponding structure of language and knowledge, where complex propositions can be analyzed into atomic propositions.

Here are some key aspects of Russell’s Logical Atomism as discussed in the sources:

• Ultimate Constituents (Simples): According to Russell’s ontology in the period around 1910-11 and in his later views, the simples of the world are particulars (which can include concrete facts or events) and universals, which encompass properties (1-adic or monadic relations) and relations. All objects are particulars. Between 1914 and 1940, events were considered simples. After 1940, most simples were seen as simple qualities, though these could also be complexes.
• Facts: Russell came to believe that “every thing that there is in the world I call a fact”. Facts are composed of simples in relation. Complex facts, like propositions about complexes, are subject to analysis into their constituent parts and the propositions describing those parts.
• Analysis: A fundamental method in Logical Atomism is philosophical analysis, which involves breaking down complex entities, concepts, or propositions into their simpler constituents. This process is crucial for understanding the structure of reality and deriving knowledge. The principle of atomicity, formulated initially by Wittgenstein and later integrated by Russell, states that “every statement about complexes can be analyzed into a statement about their constituent parts, and into those propositions which completely describe the complex”. While initially thought to be easily applicable, the practical application can be difficult, as particulars themselves may be complex and require further analysis.
• Atomic and Complex Propositions: Corresponding to the simple entities and facts are atomic propositions, which are the simplest meaningful statements. Complex propositions are built up from atomic propositions through logical connectives and generalizations. Russell’s analysis aims to reduce complex propositions to their underlying atomic components.
• Connection to Logic and Language: Logical Atomism is intrinsically linked to logic and the structure of language. Russell’s work in logic, particularly in Principia Mathematica, provided a framework for analyzing the structure of propositions and inferential relationships. The “atomistic hierarchy of sentences” reflects the way complex linguistic structures are built from simpler ones, mirroring the hierarchical structure of reality as conceived by Logical Atomism. Russell’s theory of types, developed to avoid paradoxes in logic, is closely related to the structure of propositions within this framework. The logical form of propositions is seen as reflecting the underlying structure of reality.
• Evolution of the Theory: Russell’s specific formulation of Logical Atomism and the related theory of types evolved. His earlier (1908) view treated propositions and propositional functions as “single entities,” while the PM theory (1910-13) reconstructed them as not being single entities, instead viewing them as constituents of facts. The principle of atomicity also saw a “weakened form,” allowing for the analysis of physical objects and complex facts.
• Role in Epistemology: Logical Atomism provides a foundation for empirical knowledge, positing that knowledge ultimately rests on immediate awareness (acquaintance) of simple facts or data. The process of gaining knowledge of the external world involves constructing knowledge of complex entities and relationships through logical inference and analysis, starting from this foundation of immediate experience, such as with sense-data (in his earlier period).
• Structural Realism and Challenges: In later works like The Analysis of Matter, Russell’s views connect to structural realism, which posits that objective, scientific theories describe the structural properties of the world, known indirectly by description. This approach, rooted in the idea of structure derived from basic constituents, faced challenges, such as Newman’s objection, which questioned whether knowing only the structure of objects was sufficient for knowing the objects themselves. This highlights a tension in deriving knowledge of the external world from immediate sensory data or structural descriptions alone.

In essence, Russell’s Logical Atomism, in its various iterations, sought to understand the fundamental nature of reality and knowledge through a process of logical analysis that revealed the simple constituents of complex entities and facts, mirroring this structure in the form of propositions.

This compilation features Bertrand Russell’s significant metaphysical writings, offering insights into his development as a leading analytic philosopher of the 20th century. The selections address fundamental philosophical questions, including the nature of reality beyond appearances, the distinction between particulars and universals, the principle of individuation, and the philosophical problems surrounding causation and laws. Russell’s clear and analytical approach is highlighted, demonstrating his belief that even complex philosophical ideas can be made accessible, making this collection a valuable resource for those new to metaphysics or analytic philosophy. The book also explores the implications of logical analysis for understanding the world and the relationship between physics and metaphysics.

Russell’s Metaphysics Explored

Based on the provided sources, here is a discussion of metaphysics, drawing on Bertrand Russell’s views as presented in the selections:

What is Metaphysics? Metaphysics is described as one of the most abstract areas of philosophy. It aims to uncover the fundamental nature of reality beyond mere appearance. Unlike scientific inquiry, metaphysics studies the world by using philosophical methods of analysis, reason, and argument, rather than through empirical observation. Metaphysical questions cannot be settled by looking for observable evidence. As Russell characterized it, metaphysical entities are those things supposed to be part of the world’s ultimate constituents, but are not the kind of thing that is ever empirically given. Metaphysics is not inherently more puzzling or mystifying than other branches of philosophy, such as moral philosophy or epistemology, which also deal with abstract questions non-empirically.

While a physicist and a metaphysician might consider the same subject, such as material substance, they do so in very different ways. What a scientist says is usually of little use in a metaphysical debate. For example, a physicist might say material substances are made of electrons, but the metaphysician would then ask if an electron is a bundle of qualities or has an underlying substratum. Decisions between rival metaphysical theories are made through argument and analysis.

Russell as a Metaphysician Bertrand Russell made a major and lasting contribution to metaphysics, which has been hugely influential and helped establish analytic philosophy. Although he is often depicted as an empiricist who largely rejected metaphysics, this book aims to counter that misconception, arguing that Russell was indeed a metaphysician and perhaps that his most important insights were metaphysical. He was one of the main figures to react against British idealism, which was heavily influenced by Hegelian metaphysics.

The volume Russell on Metaphysics collects a comprehensive selection of his writings on the subject, following the development of his thought. It starts with papers from his pre-analytic period, includes his realist accounts, discussions of universals, causation and laws of nature, and later thoughts on diverse questions like vagueness.

Key Metaphysical Topics in Russell’s Work (as presented in the sources) The sources highlight several key areas of metaphysics that Russell addressed:

• Idealism: The volume begins with papers from Russell’s early idealist period. Russell later developed a critique of idealism, arguing that the psychological viewpoint (like the idea that knowledge of one’s own mind is more certain than that of the external world) mistakenly failed to recognize that psychological statements also transcend the immediate given, just as physical statements do.
• Ontology: This is a significant area covered in the book. An ontology is essentially an inventory of what exists, listing categories of things like propositions, properties, and relations.
• Universals and Particulars: Russell extensively discussed the problem of universals. He considered the question of whether there is a fundamental division between universals and particulars, leaning towards the view that the dualism is ultimate. He defined particulars as entities that can only be subjects of predicates or terms of relations (logical substances) and exist in the narrow sense of the word. Universals, like properties or relations, can appear as predicates or relations and subsist rather than exist in the same sense as particulars. The question of whether predication is an ultimate relation is tied to the existence of particulars.
• Existence and Being: The sources distinguish different senses of “existence” and “being”. Being belongs to every conceivable term or object of thought, including numbers, relations, and propositions; if something can be counted, it has being. The meaning of existence used in philosophy and daily life is predicated of individuals like Socrates, but this is distinct from the sense used in mathematics or symbolic logic. Russell held that mathematics and metaphysics, being a priori, are existence-free in the philosophical sense.
• Facts: Russell discusses different kinds of facts, including particular facts (“This is white”), general facts (“All men are mortal”), positive facts (“Socrates was alive”), and negative facts (“Socrates is not alive”). The distinction between positive and negative facts is considered difficult but important. He suggests taking negative facts as ultimate, finding alternative explanations (like those involving incompatibility or molecular facts) less successful at avoiding paradox. Facts themselves are neither true nor false; truth and falsehood belong to statements, propositions, or judgments.
• Logical Fictions/Constructions: Russell applied the concept of logical fictions, arguing that certain entities are not ultimate constituents of the world but can be constructed out of empirically given things. Numbers, for example, are logical fictions (classes of classes). Physical objects like atoms are also viewed as logical fictions or constructions, replaceable by logical fictions composed of empirically given things, such as series of classes of particulars. This approach allows physics to be interpreted in terms of empirical data, without requiring belief in non-empirical metaphysical entities that physics talks about.
• Causation and Laws of Nature: Russell addressed causation and laws of nature. Modern physics, unlike older physics, views causation and laws of science as concerned with what usually happens approximately (statistical probabilities), rather than what always happens exactly.
• Philosophy of Mind (Neutral Monism): Russell’s work includes thoughts on the metaphysical question in the philosophy of mind, developing a form of neutral monism. This theory maintains that the distinction between mental and physical is a matter of arrangement or context of the same underlying material. Mental and physical events might be compresent (overlap in space-time), although whether this entails identity and establishes monism is debated. According to neutral monism, simple entities are members of both physical and mental series. A person is considered a series of experiences, without necessarily denying a metaphysical ego, but such an ego is unknowable and irrelevant to science. While physics might predict the structural properties of events in the head, it cannot necessarily predict their intrinsic qualitative nature (e.g., the subjective experience of seeing). However, actions like speaking or writing are bodily movements subject to physical laws, suggesting that the socially important part of thought might have a one-to-one relation to physical events.
• Free Will: Russell discussed the free-will problem from an idealist standpoint. He noted that both the “plain man” who believes in free will and the “up to date” scientist who rejects it often abuse metaphysics, yet metaphysics is necessary to settle their difficulties. He argued that terms like freedom and determination have narrower (fatalism vs. caprice) and broader senses; in their narrower senses, both are false, while in broader senses, both are true, with the reconciliation belonging to “metaphysical subtleties”.
• Space and Time: Russell considered debates about space and time, specifically whether they are plenal (adjectival) or punctual (relational). This distinction is tied to the choice between monism and monadism. If space is relations between non-spatial monads, time must be too; if time is a plenum (adjective), space must be too.
• Matter: Russell explored different conceptions of matter, contrasting kinematic and dynamical definitions. Matter might be defined by extension or force, and its nature is tied to questions about space and motion. The concept of punctual space/time allows gaps, unlike plenal space/time. Homogeneity of space or a plenum makes motion meaningless.

Methodology and the Role of Language Russell emphasized the importance of philosophical grammar, believing that much traditional metaphysics is filled with mistakes due to bad grammar and failure to make distinctions in philosophical grammar. Studying the principles of symbolism can help avoid fallacious inferences from symbols to things, as language has properties not shared by things in general. With caution, the properties of language may help understand the world’s structure. He argued that complete metaphysical agnosticism is incompatible with maintaining linguistic propositions, as language itself is an empirical phenomenon. The metaphysical problem of universals, for instance, presents itself in terms of finding meaning for predicate words.

The Purpose and Value of Metaphysics Russell argued that metaphysics should be pursued out of intellectual curiosity and guided by it alone, rather than seeking religious satisfaction. He criticized the idea that metaphysics could provide comfort or consolation, as the reality constructed by metaphysics often bears no relation to the world of experience and cannot offer hope or solace for present ills. While philosophy might provide aesthetic satisfaction or a certain mood, this is distinct from religious comfort which requires belief. The desire for comfort has led to fallacious reasoning in metaphysics. He believed that once metaphysical problems, like the problem of universals, are approached technically, their lack of bearing on religious belief or social consequences becomes evident. Philosophy can achieve solid results by temporarily forgetting such preoccupations and acquiring patience and devotion to detail, similar to experimental science.

Russell on the Problem of Universals

Based on the provided sources and our conversation history, here is a discussion of universals as presented through the lens of Bertrand Russell’s writings:

The Problem of Universals: Definition and Historical Context

The problem of universals is a central topic in metaphysics with a history stretching back at least to Plato. It concerns the status of what are called “universals”. Aristotle was perhaps the first to give the problem a form approaching logical correctness. His definition of a “universal” is “that which is of such a nature as to be predicated of many subjects”. An “individual” is that which is not thus predicated.

Linguistically, this relates to the distinction between subject and predicate. In “Socrates is human,” “Socrates” is the subject, and “human” is the predicate. The predicate “human” can attach to many other subjects besides Socrates. Even if only one man existed, the statement “this is human” could still be significant, though false, if “this” referred to something else like a cat or dog. Thus, a universal does not need to be truly predicable of many things, only significantly predicable. This distinction is clear in any language with subject-predicate syntax.

The metaphysical problem, distinct from the linguistic one, asks what is meant by words that are predicates. What does “human” mean? It’s not something with a definite position in space and time, as it’s present in every man, not just Socrates. You cannot point to it, it is not born, and it does not die. It has a name but no physical location. This leads to the question of its nature – what kind of thing is it? Aristotle considered a universal a “such,” not a “this” – a kind, not an individual thing, and not a substance, as the substance of each thing is peculiar to it, whereas a universal is common.

Historically, realists held that universals exist and predicates mean universals similarly to how proper names mean persons or things. Nominalists, conversely, held that universals are linguistic creations, with nothing outside language corresponding to a predicate’s meaning. Medieval philosophers like Aquinas and Occam, while generally nominalists regarding human knowledge, conceded God must have had universals (like “human being”) in mind before creation. Berkeley and Hume were prominent modern nominalists in the British Isles, denying not only universals in the world but also abstract ideas in the mind, arguing that general words function by our ignoring particular features of specific instances.

Russell’s Views on Universals

Russell made significant contributions to the discussion of universals. His initial position in The Problems of Philosophy (1912) was described as a Platonic answer, suggesting particulars participate in a common nature or essence. He argued for the existence of universals, stating they are “anything which may be shared by many particulars”. Russell contended that universals do not exist in space and time; unlike particulars, they are “nowhere and nowhen”. They also do not have a mental existence but exist independently of our thoughts about them. Instead of existing, universals have being or subsistence. The world of being (universals) is superior to the fleeting world of particulars, though the latter is more important to our lives.

However, he also made the claim that we are acquainted with universals in sense-data. This seems to contradict the idea of universals being supra-sensible and located nowhere. He suggested that knowledge of universals is gained through a process of abstraction from particular instances, taking what is common and rejecting what is particular. This process, however, is problematic, as it seems to require prior knowledge of the universal to guide the abstraction.

Russell later revisited the problem, expressing confidence that modern logic could provide a definitive solution. He believed the solution would be technical and have no bearing on religious philosophy, empiricist philosophy, or social consequences, criticizing past philosophers (like Plato and Leibniz) for linking the problem to such broader issues. He saw connecting the problem to technical details as a way to remove bias and irrelevant preoccupations.

Argument for the Existence of Universals (Argument from Resemblance)

One of Russell’s notable arguments for the existence of universals, particularly relations, is the argument from resemblance. Nominalists attempting to avoid universals must at least concede that white particulars resemble each other. But the resemblance between two white things must be the same resemblance as that between two red things. While objects may resemble each other in different ways (color, shape), the relation of resemblance itself seems to be a single entity involved in each case. Therefore, Russell argued, at least the relation of resemblance must be a universal.

He argues against explaining away similarity by saying that similar stimuli produce similar reactions (e.g., seeing two red discs prompts saying “red” each time). Are we saying the same thing about the discs and the utterances when we call them similar, or just similar things? If the latter, it leads to a vicious endless regress: the similarity of the wholes AB and CD (where A and B are similar, C and D are similar) is explained by their similarity, which would require explaining the similarity of these similarities by their similarity, and so on. This regress suggests that similarity must be a true universal. He concludes, with hesitation, that universals exist, or at least general words are not the whole story. Similarity, at minimum, must be admitted, making elaborate efforts to exclude other universals hardly worthwhile.

Russell clarifies that the argument proves the necessity of the word “similar,” but this word is necessary because there are pairs of similar things, and the similarity of two things is a non-linguistic fact.

Universals vs. Particulars

A fundamental division in metaphysics is between universals and particulars. Russell believed this dualism is ultimate. He sought criteria for distinguishing them.

• Spatial Location: One criterion Russell used is that a particular can only be in one place at a time, whereas a universal can have instances in different places simultaneously. Whiteness, if it exists, exists wherever there are white things. A particular patch of white, however, cannot be in two places at once. The logical possibility of exactly similar things co-existing in different places, combined with the impossibility of things in different places at the same time being numerically identical, necessitates admitting particulars (instances of universals) exist in places, not the universals themselves. The fact that certain spatial relations (like being outside each other) imply diversity of their terms, and that things can be indistinguishable in qualities but numerically diverse due to these relations, forces the admission of particulars distinct from universals or collections of universals.
• Logical Role: Particulars are entities that can only be subjects of predicates or terms of relations. They are analogous to traditional logical substances. Universals, on the other hand, can appear as predicates or relations.
• Existence vs. Subsistence: Particulars exist in the narrow sense of the word; they can be fleeting and need not be causally independent. Universals, however, do not exist in the same sense but rather subsist. They do not exist in time.
• Predication: The distinction between particulars and universals is tied to the question of whether predication is an ultimate, simple, asymmetrical relation. If there are particulars, predication is ultimate: “This is white” expresses a relation between a particular and whiteness. If particulars are rejected, predication is not ultimate; “This is white” might mean whiteness is a quality in this place. Russell, believing particulars exist, views predication as an ultimate relation involving a fundamental logical difference between its terms.

Particulars as Bundles of Qualities (Later View)

In a later discussion, prompted by revisiting the problem of universals, Russell ventured the view that a “thing” is nothing more than a bundle of qualities. These qualities would traditionally be called universals. This view implies that two different things cannot be exactly alike in all their qualities (including relational qualities), as they would then be one thing. Diversity is conferred by spatio-temporal position, which Russell explains not just by saying they occupy different parts of space, but by suggesting position is defined by certain qualities (like “more-or-less-right-or-leftness” and “more-or-less-up-or-downness” in visual perception).

On this view, the simplest meanings belong to words denoting qualities (universals), like “redness” or “sweetness”. Particulars, like Socrates or a rose, become “bundles of qualities”. A statement like “this rose is red” is analyzed not as a subject-predicate statement about a particular (“this rose”), but as asserting that certain spatial qualities, the qualities defining “rose,” and redness all coexist or are compresent in a region. Compresence is the relation between qualities that partially or completely overlap in space-time. A “place” can be defined as a bundle of compresent qualities.

This later view suggests that what are commonly called particulars are bundles of qualities (universals) that include enough spatio-temporal qualities to ensure they occupy a continuous region. Their logical and syntactical status does not differ fundamentally from qualities like redness. This shifts the problem of universals; instead of asking about qualities like “red,” we ask about properties of qualities, such as “colour”.

The Role of Language and Ontology

Russell emphasized the importance of philosophical grammar and syntax in understanding metaphysical problems. He believed mistakes in traditional metaphysics often arose from “bad grammar”. While caution is needed, the properties of language can help understand the world’s structure. For example, the existence of universals can be inferred from language. Russell argued that complete metaphysical agnosticism is incompatible with maintaining linguistic propositions, as language itself is an empirical phenomenon.

He connected the linguistic distinction of subject and predicate to the ontological distinction of things and concepts (his earlier terms for particulars and universals). Words are divided into substantives, adjectives, and verbs. Substantives can denote things (particulars), while adjectives and verbs denote concepts (universals/relations). Concepts are terms usable as both predicates (“Socrates is human”) and subjects (“humanity belongs to Socrates”), whereas things (particulars) can only be subjects.

In his later view, the distinction between proper names (denoting particulars) and predicates (denoting universals) is reformulated. Proper names denote spatio-temporally continuous series of occurrences (like Socrates or France), while predicates denote something in discontinuous portions (like whiteness). However, even things denoted by proper names, like “Tom,” are recognized by qualities (universals) like red hair or blue eyes. The name “Tom” applies primarily to whatever has these qualities, suggesting “Tom” denotes primarily a bundle of universals. Primary vocabulary consists of words denoting universals, learned through association with similar occurrences. Words for particulars, if possible, are learned later and involve analysis.

Russell also considered the ontological status of relations. While acknowledging their necessity in language (“A is above B”), he questioned if they denote an actual ingredient of the fact. He explored whether a relation could be a quality of the whole composed of its terms, but this approach faced difficulties with asymmetric relations and led back to needing universals (like “vertical order” or “similarity-in-a-certain-respect”). He concluded that relations like temporal order exist independently of language.

While the need for relation-words is clear, whether the word “similarity” (as a substantive) is needed in isolation, or only “similar” (as an adjective/verb), was debated. This is linked to the idea of relation-words being syncategorematic – meaningful only in context with terms. However, Russell ultimately argues that the fact that “similar” is necessary because there are pairs of similar things implies a non-linguistic fact about the world, just as “yellow” implies the yellowness of things.

In summary, Russell grappled with the problem of universals throughout his career, moving from an early Platonic realism to a sophisticated analysis involving logic, language, and ontology. He consistently argued for the ultimate reality of universals (or at least similarity) and maintained the fundamental distinction between universals and particulars, though his understanding of particulars evolved towards viewing them as constructed from universals (qualities) in spatiotemporal relations. He emphasized that the problem is a technical one about the structure of reality, reflected in language, and should be pursued without regard for potential religious or social consequences.

Russell on Causality: From Rejection to Reintegration

Based on the provided sources, a discussion of causality in the context of Bertrand Russell’s writings reveals a complex and evolving perspective, marked initially by a strong rejection of traditional notions and later by a reintegration of the concept into the foundations of science.

Russell’s Early Deflationism and Rejection of Traditional Causality

In earlier papers, such as “On the Notion of Cause” (Paper 14, 1913), Russell argues that the word “cause” is “so inextricably bound up with misleading associations as to make its complete extrusion from the philosophical vocabulary desirable”. He believes the “law of causality” is a “relic of a bygone age” that survives only because it is erroneously thought to do no harm. Russell notes that in advanced sciences like gravitational astronomy, the word “cause” never occurs. Instead, science utilizes formulae, such as equations like F = ma, in which nothing can be identified purely as cause or effect. These formulae, Russell contends, “eliminate” causality altogether, rather than merely being a more accurate way of talking about it.

Russell critically examines traditional philosophical understandings of cause, including definitions from Baldwin’s Dictionary. He finds definitions linking causality to “necessary connection” or “taking place in consequence of another process” to be problematic. The notion of necessity is often tied to the idea of something being “true under all circumstances,” which Russell argues applies to propositional functions, not simple propositions. Interpreting causality in this light might lead to a definition stating that whenever an event e1 occurs at time t1, an event e2 follows after a specific interval. However, he raises “insuperable difficulties” with the traditional idea of cause and effect being contiguous in time, arguing that the time-series is compact, meaning there are no contiguous instants. Any finite time interval between cause and effect allows for other intervening circumstances, suggesting the supposed cause is not, by itself, adequate to ensure the effect.

Russell also challenges common maxims associated with causality:

• Cause and effect must resemble each other: Science shows them to be “very widely dissimilar”. This maxim is operative, for instance, in the thought that mind could not have grown up in a purely material universe.
• Cause is analogous to volition: This view, suggesting an “intelligible nexus” between cause and effect, is rejected because modern physics leaves no room for such a connection between two events. The nexus desired seems to mean something “familiar to imagination”.
• The cause compels the effect: Russell argues that “compulsion” is a complex notion involving “thwarted desire” and is inapplicable where desire is not present. In the absence of volition, it is “misleading to regard the cause as compelling the effect”. He also refutes the vaguer form that the cause “determines” the effect in a way the effect does not determine the cause, showing that any supposed lack of symmetry is “illusory” when considering pluralities of causes or effects.
• A cause cannot operate when it has ceased to exist: Russell calls this a “common maxim” and “still more common unexpressed prejudice”. It is based on the mistaken supposition that causes “operate” at all, a notion derived from assimilating causes to volitions. If causes and effects are separated by a finite time interval, as they must be if they exist, then effects necessarily occur after their causes have ceased to exist.
• A cause cannot operate except where it is: This maxim underlies prejudice against “action at a distance” and relies on the assumption that causes “operate” in an obscure analogy to volitions.

In place of the traditional notion, Russell suggests that science deals with uniformities of sequence, where the earlier event can be called the cause and the later the effect if observed frequently. However, this sequence is only probable, not necessary. Furthermore, not every event needs a cause in this sense, and any sufficiently frequent sequence (like night causing day) could be called causal. He contrasts this with the idea of “invariable succession,” which Mill linked to the Law of Causation, noting that such universal causal laws, as Mill conceived them, are not found in advanced science. Scientific laws consist not in “sameness of causes and effects” but in “sameness of relations” or, more accurately, “sameness of differential equations”.

Causality, Determinism, and Laws of Nature

Russell’s views on causality are closely intertwined with the debate on determinism and laws of nature. He views laws as descriptions of uniformity. In his earlier paper “The Free-Will Problem from an Idealist Standpoint” (Paper 3, 1895), influenced by idealism and Kant, he proposed a “reconciliationist” or “compatibilist” solution to the free will problem, arguing that free will is compatible with determinism. This position relies on an understanding of laws of nature as descriptions of what happens, not entities that compel or control events. A law is “nothing but a compendious description” of events. This understanding aligns with a Humean metaphysics in which there are no necessary connections between events; laws are simply discerned patterns of regularities.

Russell defines a “deterministic system” as one where, given certain data about the system at specified times, it is possible to infer events at any other time. Whether our volitions belong to such a system is a “mere question of fact,” and empirical evidence suggests uniformities in volitions, though it might not be overwhelming. The “subjective sense of freedom” does not refute determinism, as it is based on the mistaken idea that causes compel their effects. Even if volitions are “mechanically determined” (part of a system with purely material determinants), this does not imply the supremacy of matter over mind, as the same system might be susceptible to both material and mental determinants. The notion of necessity often associated with determinism is a “confused notion”. Russell concludes that the problem of free will versus determinism is “mainly illusory,” arising from erroneous notions about causality.

Connecting Causality to Physics and Ontology

Physics, in Russell’s view, replaces the notion of “force” with “laws of correlation”. These correlations allow events to be grouped, and this is “all that is true in the old notion of causality”. These correlations or laws of correlation are what lead to the definition of permanent “things”. Instead of persistent substances, things (like tables, chairs, electrons, or even light-rays) are seen as “series of more or less similar phenomena, connected, not by substantial identity, but by certain causal connections”. They are “strings of events or of sets of events” connected by discoverable laws. Physics aims to discover the “causal skeleton of the world”.

Later Shift: Causality as a Scientific Postulate

In a “marked contrast” to his earlier view, Russell’s later work (e.g., Paper 17, 1948) presents a rehabilitation of causality. He now states that the power of science rests in the discovery of causal laws and that science “assumes causality in some sense”. Causality becomes a “fundamental postulate of science” that allows inference about one region of space-time from another.

In this later view, a “causal law” is defined as a general principle allowing inference from data about certain space-time regions to something about other regions. This inference may be only probable, but the principle must allow probability “considerably more than a half”. This definition is wide, allowing inferences backwards or forwards in time, involving complex data, and permitting probabilistic laws. This revised view allows for “crude generalisations from which common sense starts,” like “bread nourishes,” which permit exceptions.

This belief in causality, allowing inference from sensations/perceptions (events in us) to external physical objects, is fundamental to our knowledge of the physical world. The justification of this belief belongs to epistemology, but science methodologically assumes it. The validity of scientific method depends on assumptions that can be roughly stated as the postulate that there are general laws of certain kinds. Russell calls this the “faith” of science: there are formulae (causal laws) connecting events, exhibiting spatio-temporal continuity, and predictions based on these formulae are confirmed. Possible postulates for scientific method include the law of causality, uniformity of nature, reign of law, and belief in natural kinds.

Despite this later acceptance, Russell still distinguishes this scientific concept from the traditional philosophical notion of cause as an “invariable antecedent” where the sequence is felt to be “necessary”. However, he admits “reasons… for admitting laws of the form ‘A causes B’,” provided there are “suitable safeguards and limitations”. This is particularly relevant for defining the identity of physical objects over time via the concept of a “causal line” – a series of events where knowledge of some allows inference about others independently of the environment. When two events are part of one causal line, the earlier can be said to “cause” the later. Physics using differential equations can be seen as stating “what is tending to happen,” resolving the conception of “cause” into that of “law”.

In summary, Russell’s perspective on causality shifts from an outright rejection of the traditional notion as a misleading relic to a later acceptance of causal laws as fundamental postulates necessary for scientific inference and the construction of our understanding of the physical world, redefined through concepts like functional relations, differential equations, correlations, and causal lines. He consistently argues against the traditional idea of cause as an agent exerting force or compulsion.

Russell on Language, Metaphysics, and Philosophy

Based on the provided sources and our previous discussion on Causation, Bertrand Russell viewed the study of language as crucial for philosophical inquiry, particularly in metaphysics and logic. However, his perspective comes with significant caveats and develops over time.

Here’s a discussion of Russell’s views on language as presented in the sources:

1. Language as a Guide, Not a Master, to Metaphysics:

• Russell initially advocated for an ontology “guided by the logic of language”. He believed the study of grammar is “capable of throwing far more light on philosophical questions than is commonly supposed”. Grammar can serve as “prima facie evidence” of philosophical differences and is a “source of discovery”. He suggested grammar “brings us much nearer to a correct logic than the current opinions of philosophers” and should be taken as a “guide”.
• He explicitly applied this method, using grammatical distinctions (like substantive and adjective) as a guide to ontological distinctions (like substance and attribute, things and concepts). He believed “every word occurring in a sentence must have some meaning”.
• However, even in this earlier phase, he expressed reservations about language dictating ontology.
• Later, this caution solidified, with the explicit statement that “to allow grammar to dictate our metaphysics is now generally recognized to be dangerous”. This shift in emphasis, though not necessarily a complete inconsistency, marks a distinction in his approach.

1. The Fallacy of Verbalism:

• A central theme in Russell’s view is the danger of inferring properties of the world from properties of language. He calls this the “fallacy of verbalism”.
• He argues that “almost all thinking that purports to be philosophical or logical consists in attributing to the world the properties of language”. Since language exists, it has properties, but many properties of language are “not shared by things in general,” and when these “intrude into our metaphysic it becomes altogether misleading”.
• He specifically identifies the traditional notions of “existence” and “reality” as arising “entirely through mistakes as to symbolism”. Clearing up the “muddle about symbolism” reveals that much said about existence is simply a mistake.
• The influence of symbolism on philosophy is often unconscious, and studying its principles can provide negative results by helping avoid fallacious inferences from symbols to things.

1. Language as Representation and the Nature of Vagueness:

• Russell views language as a system of symbolism, a type of representation. Every word is a symbol. A symbol “means” something else.
• He argues emphatically that vagueness and precision are characteristics of representation, not of the things represented. “Things are what they are, and there is an end of it”.
• He explicitly states that “only representations are vague” and there are “no vague objects or vague properties of objects”.
• Vagueness in language is inevitable. It arises because concepts are derived from vague sensory evidence and because meaning is a “one-many relation” rather than a one-one relation (as it would be in an accurate language).
• He uses examples like “red” and “bald” to illustrate this linguistic vagueness, arguing it invalidates classical logic rules like the law of excluded middle when applied to vague words.

1. Language, Ontology, and the Problem of Universals:

• Russell analyzes the relationship between different types of words and the entities they signify. Propositions, in his view, contain the entities indicated by words, not the words themselves.
• He distinguishes terms indicated by proper names (“things” or “particulars”) from terms indicated by other words (“concepts,” including those for adjectives and verbs/relations).
• The linguistic distinction of subject and predicate is seen as suggesting the metaphysical problem of universals.
• Children learning language via ostensive definition rely on repetition and recognition of qualities (which Russell considers universals). This suggests our primary vocabulary consists entirely of words denoting universals. Knowledge of these qualities, denoted by universal words, is “the easiest and most primitive knowledge that we possess”.
• He challenges nominalism (the view that universals are just words) by arguing that words themselves are classes of instances, and if universals are denied in the world, they must logically be denied in language too, which is untenable.
• He argues that the very need for relation-words, particularly for relations like similarity, suggests the existence of universals in the non-linguistic world. Words like “before” and “above” “mean” something that occurs in perception. Similarity itself is a “non-linguistic fact” that makes the word “similar” necessary.
• While some uses of relation-words (as substantives, e.g., “similarity”) might be argued to be syncategorematic (meaningful only in context), Russell believes that the need for relation-words points to something objective: “things are related”.
• He notes that the word “precedes,” although it means a relation, “is not a relation,” which he sees as a source of philosophical muddle about relations.
• Ultimately, he concludes that “complete metaphysical agnosticism is not compatible with the maintenance of linguistic propositions” and that studying syntax can lead to knowledge about the structure of the world.

1. Critique of Ordinary Language Philosophy:

• Russell strongly attacked the “ordinary language” philosophy movement.
• He saw this movement as claiming that all possible philosophical knowledge could be discovered through the analysis of ordinary, non-philosophical language alone.
• This contrasted with his own more cautious view that language analysis, particularly of philosophical grammar or a logical language, could help in understanding the world’s structure, but not that ordinary language was sufficient for all philosophical discovery.

In sum, Russell saw language as a crucial tool for philosophical analysis, capable of guiding our understanding of the world’s structure and revealing fundamental ontological categories like universals. However, he issued strong warnings against being misled by linguistic structures, emphasizing that properties of language should not be automatically attributed to the world. His analysis of vagueness is a prime example of distinguishing between linguistic properties and non-linguistic reality.

Russell’s Philosophy: Logic, Language, and Reality

Drawing on the sources and our conversation history, Logic holds a foundational and multifaceted role in Bertrand Russell’s philosophy.

The Centrality of Logic and Critique of Tradition:

Russell viewed logic as indispensable for philosophical inquiry, going so far as to suggest that what he calls “symbolical logic” is simply “logic” itself, implying nothing else truly warrants the name. He argued forcefully that the traditional logic, particularly the subject-predicate logic inherited largely from Aristotle and still prevalent in the work of idealists like Bradley, was fundamentally inadequate. This old logic, based on erroneous beliefs, led philosophers to counterintuitive positions and fallacies. Traditional elementary logic is seen as an “almost fatal barrier to clear thinking” unless a “new technique” is acquired. Russell’s “new logic”, or “mathematical logic”, provided the tools to diagnose these fallacies and move philosophical analysis forward.

Logic, Ontology, and Metaphysics:

Logic is deeply intertwined with ontology – the study of what exists. Russell’s philosophy advocates for an ontology “guided by the logic of language”. While cautioning against letting grammar dictate metaphysics (a view more solidified in his later work), he initially saw grammar as a crucial “guide” and “prima facie evidence” for philosophical distinctions, bringing one “much nearer to a correct logic”. The new logic itself has a “metaphysical basis,” assuming the existence of entities such as real and mind-independent propositions, objective truth and falsehood, relations with independence from their terms, and a plurality of objects. Russell came to believe that “complete metaphysical agnosticism is not compatible with the maintenance of linguistic propositions”. By studying language, particularly its syntax in a “logical language,” one can gain considerable knowledge about “the structure of the world”. However, the danger of attributing properties of language to the world (the “fallacy of verbalism”) is also a key concern, emphasizing that while language can guide, it should not be allowed to dictate metaphysics.

Logical Analysis and Atomism:

A core application of Russell’s logic is in philosophical analysis, particularly the approach known as “logical atomism”. Logic enables the analysis of complex things or propositions down to “ultimate simples” or “logical atoms”. These atoms are the unanalysable residues at the end of the analytical process; they are “purely logical” and need not be physical. Russell distinguishes between terms and the relations that relate them in a complex. Logic helps to determine the “smallest empirical apparatus” or “smallest apparatus” (not necessarily wholly empirical) out of which propositions can be built, using a minimum of “simple undefined things” and “undemonstrated premisses”. This process, guided by Occam’s Razor, diminishes the risk of error by reducing the required assumptions. Through logical analysis, entities previously considered fundamental metaphysical substances (like atoms in physics or persistent desks) can be revealed as “logical fictions” or constructions built from empirical data.

Logic and Language Structure:

The structure of language provides insights for logic and ontology. Distinctions in philosophical grammar, such as those between proper names, adjectives, and verbs, correspond to distinctions between different types of entities: particulars (indicated by proper names) and concepts (indicated by adjectives and verbs). Propositions themselves contain the entities indicated by words, not the words as symbols. Verbs, in a logical sense, are concepts capable of occurring in a proposition without being a term, and every proposition must contain one verb. Russell suggests that every verb, logically speaking, may be regarded as asserting a relation. The capacity for combining terms into a complex is the defining characteristic of verbs. The linguistic distinction of subject and predicate is linked to the metaphysical problem of universals and the relation of predication.

Logic and Propositions/Facts:

Logic primarily concerns propositions, which are the “typical vehicle on the duality of truth and falsehood”. Atomic sentences, devoid of logical words like “not,” “or,” “and,” “if,” “all,” “some,” are the building blocks for molecular propositions. Atomic propositions correspond to facts, which exist “whatever we may choose to think about them”. Facts are what make propositions true or false. Russell grapples with the question of whether there are “negative facts” (e.g., the fact that “Socrates is not alive”) corresponding to negative propositions. He ultimately inclines towards accepting negative facts, finding alternative explanations like reducing negation to incompatibility between propositions problematic, partly because propositions themselves are not “real” in the same sense facts are when making an inventory of the world.

Logic and Existence:

Russell emphasizes a crucial distinction regarding the word “existence,” particularly between its philosophical/common sense (predicated of individuals, like “God exists” or “Socrates existed”) and its use in “symbolic logic”. In symbolic logic, existence is a technical term meaning a class “has at least one member”. Entities considered in mathematics or symbolic logic (like numbers or principles of the syllogism) do not exist in the philosophical sense, but they are “real” to symbolic logic and mathematics. This logical sense of existence clarifies the “existential import of propositions,” showing that certain types of propositions (A and E) do not imply the existence (in the logical sense) of their subjects, while others (I and O) do.

Logic, Vagueness, and Precision:

Russell argues that “all language is vague” because meaning is a “one-many relation”. Vagueness and precision are properties of representation (language, symbols), not of the things represented; there are “no vague objects or vague properties of objects”. Logical words, while seeming precise, ultimately rely on the notions of “true” and “false,” which are themselves vague when applied to propositions containing vague non-logical words. Thus, even logical propositions, as we frame them, have a degree of vagueness. However, logical words apply essentially to symbols, and we can “imagine what a precise symbolism would be,” allowing us to conceive a precise meaning for logical terms. This ability to conceive precision, even if not attainable in practice, leads Russell to state that “logic takes us nearer to heaven than most other studies”.

Logic and the Advancement of Science:

Russell sees a close relationship between logic and the sciences. A “logic of the sciences” involves understanding the fundamental ideas and potential contradictions within scientific systems. Mathematical logic provides the technical apparatus needed for analyzing scientific propositions and constructing theories with minimum assumptions. Russell suggests that problems soluble by logical methods often move from the realm of philosophy (what we don’t know) to that of science (what we more or less know). This application of mathematical logic can make philosophical inquiry more “dry, precise, methodical,” diminishing its speculative freedom but increasing its certainty.
