III. Answer Key

1. Russell’s logicist project aimed to demonstrate that mathematics could be derived from logic. The primary goal was to show that mathematical truths were ultimately logical truths, thereby establishing mathematics on a secure foundation.
2. Acquaintance is direct, unmediated knowledge of something through immediate experience, while description is knowledge of something indirectly through a description that uniquely identifies it. Russell believed that all knowledge ultimately rests on acquaintance with sense-data or universals.
3. Russell’s theory of descriptions analyzes definite descriptions (e.g., “the king of France”) by breaking them down into logically simpler components. It eliminates the need to posit nonexistent entities as referents of these descriptions, resolving philosophical puzzles about existence and reference.
4. Logical atomism is a philosophical view that holds that the world is composed of simple, independent facts, and that language should mirror this structure. It asserts that complex propositions can be analyzed into simpler, atomic propositions that correspond to these atomic facts.
5. Sense-data are the immediate objects of perception, such as colors, sounds, and textures. Russell argued that our knowledge of the external world is based on inferences from sense-data, which are the building blocks of our empirical knowledge.
6. Russell’s paradox arises from considering the set of all sets that do not contain themselves. The paradox occurs when asking whether this set contains itself, leading to a contradiction regardless of the answer.
7. Russell’s theory of types is a hierarchical system designed to avoid logical paradoxes by restricting the kinds of statements that can be made about sets and properties. It asserts that a statement about all statements of a certain type must be of a higher type than the statements it refers to.
8. The ‘preabandonment doctrine’ refers to the sense-data having indubitable, infallible, and immediate properties as data from empirical knowledge. This position is subtlety and then less marked following the formulation.
9. The features of indexicals are: the designatum of indexicals constantly changes; indexicals designate without description; the designatum of an indexical is directly sensed; indexicals designate particular things; indexicals designate particulars.
10. Wittgenstein’s criticism at the time argued that in order to judge, one needs to be acquainted with the constituents of the proposition. It was thought that such acquaintance makes the judgment intensional.

Rereading Russell: Metaphysics and Epistemology

Okay, here is a briefing document outlining the main themes and important ideas from the provided excerpts of “Rereading Russell: Essays on Bertrand Russell’s Metaphysics and Epistemology.”

Briefing Document: Rereading Russell – Essays on Bertrand Russell’s Metaphysics and Epistemology

Overview:

This briefing summarizes key themes and arguments presented in the excerpts from the book “Rereading Russell: Essays on Bertrand Russell’s Metaphysics and Epistemology.” The book covers various aspects of Russell’s philosophical work, from his early idealism to his later analytic philosophy, focusing on metaphysics, epistemology, and the philosophy of science. The essays delve into specific topics such as Russell’s theory of descriptions, logical atomism, theory of types, and his evolving views on sense-data and perception.

Main Themes and Ideas:

1. Evolution of Russell’s Philosophy: The collection highlights the significant changes and development of Russell’s philosophical views throughout his career. The editors state, “One aim of this volume is to direct attention to Russell’s later metaphysics and epistemology… However, the later work cannot be properly understood except as a development of the earlier, and so we have prepared a volume that deals with Russell’s metaphysics and epistemology in all its phases.” The book examines his shift from idealism to logical atomism and his later modifications of these views. It acknowledges that Russell revised his views often, driven by problems or solutions and remarks by Wittgenstein.
2. The Theory of Descriptions: Several essays engage with Russell’s theory of descriptions, as presented in his famous paper “On Denoting.” The significance of this theory is emphasized as a turning point in 20th-century analytic philosophy. One essay aims to examine what this article holds “in the consequence of that view in OD, not in Russell’s reasons for coming to hold that view.” The core of the theory is to provide an explanation for the meaning and generality of descriptions without needing to posit the existence of described entities.
3. Russell’s Logicism and Ramification: The book addresses Russell’s logicist project of deriving mathematics from logic, particularly as presented in Principia Mathematica. One essay considers “Russell’s reasons for ramification,” an intricate part of Russell’s theory of types. The ramified theory of types attempts to resolve paradoxes by introducing a hierarchy of functions and propositions, but was also criticized for its complexity and its apparent deviation from pure logicism. One author concludes that the project, though ambitious, faced several issues and contained “mathematical content.”
4. Logical Atomism and the Nature of Facts: The book explores Russell’s logical atomism, which posits that the world is composed of simple, atomic facts. Complex facts are constructed from these atomic facts through logical connectives. This theme is present in the essays discussing his theory of types and the analysis of sentences into their logical forms. “The philosophy of Logical Atomism is Russell’s presentation of analytic philosophy… analyzing entities and sentences into their logical atoms.”
5. Sense-Data and Perception: Russell’s evolving views on sense-data and perception are a central topic. The essays trace his changing position on the certainty and role of sense-data in knowledge. One essay discusses Russell’s “preabandonment doctrine of sense-data” and how it evolved into his later views on experience and perception. There is exploration of the degree to which sense-data were ultimately abandoned as indubitable, immediate elements of experience.
6. Indexicals and Scientific Knowledge: An essay is devoted to Russell’s treatment of indexicals (words like “I,” “here,” “now”) and their relationship to scientific knowledge. The book examines Russell’s claim that indexicals are ultimately eliminable in favor of objective, spatio-temporal coordinates in scientific descriptions of the world. This claim touches upon the nature of subjectivity and objectivity in knowledge.
7. Russell’s Theory of Types: One essay focuses specifically on “Russell’s Theory of Logical Types and the Atomistic Hierarchy of Sentences.” The essay explores the development of this theory, particularly as it relates to the resolution of logical paradoxes and the structure of language and reality.

Specific Quotes and Supporting Details:

• On the scope of the book: “The volume thus covers the entire body of Russell’s metaphysics, epistemology, and philosophy of science; and it reveals continuities running through the often noted differences among various phases of his philosophy.”
• On Russell’s method: “Bertrand Russell produces a new system of philosophy each year or so.” This highlights the dynamic nature of Russell’s philosophical system.
• On ramification: “Ramification of a domain of abstract entities is the result of requiring that legitimate specifications of such entities be predicative.” This explanation encapsulates the essential motivation of ramification.
• On the nature of logic: “Russell took logic to be completely universal. Logic is constituted by the most general laws about the logical furniture of the universe: laws to which all reasoning is subject.”
• On Russell’s view on philosophy: “…in philosophy we follow the inverse direction: from the complex and relatively concrete we proceed towards the simple and abstract by means of analysis-seeking, seeking in the process, to eliminate the particularity of the original subject-matter.”

It aims to provide a more nuanced understanding of Russell’s philosophy and its lasting impact on the field.

Russell’s Philosophical Concepts: An Overview

Russell FAQ

• What are the major periods in Russell’s philosophical development?
• Russell’s philosophical work is often divided into several periods. These include:

1. The pre-analytic period (1893-1899), influenced by Kantian and German idealist philosophy.
2. The logical period (1900-1910), where he developed symbolic logic and began working on Principia Mathematica (PM).
3. The early analytic period (1911-1918), characterized by the application of logical analysis to metaphysical and epistemological problems.
4. The middle analytic period (1919-1927), during which Russell applied his analytic methods to problems in physics and perception.
5. The later period (1927 onwards) which emphasized empiricism and scientific philosophy.

• What was Russell’s “theory of descriptions” and why was it important?
• Russell’s theory of descriptions, introduced in “On Denoting,” is a method for analyzing definite descriptions (phrases like “the king of France”). He argued that these phrases don’t refer to nonexistent entities, but rather contribute to the meaning of the entire proposition. This theory was crucial as it allowed Russell to avoid accepting nonexistent entities into his ontology and provided a powerful tool for logical analysis.
• What is the significance of Principia Mathematica (PM)?
• Principia Mathematica (PM), co-authored with A.N. Whitehead, is a landmark work in logic and mathematics. It aimed to derive mathematics from logic, establishing a formal system based on axioms and inference rules. PM is important because it demonstrated the power of symbolic logic and significantly influenced the development of both logic and the foundations of mathematics.
• What is Russell’s theory of types, and what problem was it intended to solve?
• Russell’s theory of types was developed to resolve paradoxes like Russell’s paradox, which showed that the unrestricted comprehension axiom in set theory leads to contradiction. The theory introduces a hierarchy of types to avoid self-referential statements. It restricts what sets can contain other sets so self-membership is disallowed. This ensures that definitions don’t create classes that include themselves, thus blocking Russell’s paradox.
• What was Russell’s view on sense-data, and how did it evolve throughout his career?
• Russell initially held that our knowledge of the external world is based on sense-data (immediate experiences like colors, sounds, etc.). He later “postabandoned” the idea that sense data are infallible and immediate data, integrating them into the causal process of perception. He moved from viewing them as the foundations of knowledge to seeing them as parts of a complex, inferential process. In his later works, they are replaced with neural excitations or events in a more neutral-monist framework.
• What role does the concept of “acquaintance” play in Russell’s epistemology?
• “Acquaintance,” in Russell’s epistemology, refers to direct and immediate knowledge of something. For Russell, we are acquainted with sense-data and perhaps universals. Knowledge by acquaintance is contrasted with knowledge by description, which involves knowing about something without direct experience. Acquaintance is foundational for Russell, as it is the basis upon which all other knowledge is built.
• What is “ramification” in the context of Russell’s logic?
• Ramification refers to the imposition of restrictions on ranges to arise from the universality of logic, especially from the idea that anything expressible at all can be expressed inside his framework. Any additional quantifiers affects the order of ramification that would arise from a constraint of predicativity.
• How did Russell’s views on indexicals (words like “I,” “here,” and “now”) evolve and what impact did this have on his epistemology?

Russell initially dismissed indexicals as unnecessary for knowledge, advocating for their replacement with objective space-time coordinates. He tried to eliminate what he called egocentric particulars. Later, he recognized the importance of indexicals as expressing a unique relationship between sensory experience and point of view, though without fully resolving their place in his system.

Bertrand Russell: Epistemology and Metaphysics

Russell’s contributions to epistemology and metaphysics are substantial, and his views evolved considerably throughout his career.

Key aspects of Russell’s theory of knowledge include:

• 1913 Theory of Knowledge Manuscript: David Pears examines Russell’s suppressed manuscript, particularly due to Wittgenstein’s criticisms concerning the development of logical atomism. This manuscript reveals Russell’s attempt to explain a subject’s ability to understand contingent propositions or judgments using acquaintance.
• Acquaintance: Reliance on what Pears calls extensional acquaintance leads Russell to extend from bringing S’s intention or knowledge of types of objects into the explanation.
• Theory of Descriptions: According to Peter Hylton, Russell introduces the theory of generality and emphasizes its importance to logic and mathematics. The theory of descriptions allows for the elimination of certain assumptions and provides a method for analyzing denoting concepts.
• Logical Atomism: The status of objects as complex single entities that can be named was important in Russell’s 1910-13 work. According to Nino Cocchiarella, Russell concluded by 1913 that only particulars can be named and that facts cannot be named. Russell’s logical atomism is what determines what Russell described as the atomistic hierarchy.
• Sense-Data: C. Wade Savage discusses sense-data as the ultimate data in a standard foundationalist account of empirical knowledge. Russell used “awareness” or “acquaintance” to denote the object of sensory acquaintance and was convinced William James had been right in denying the relational character of sensations.
• Indexicals: Janet Farrell Smith writes about Russell’s stance on indexicals, which are logically strict names, and scientific knowledge. Russell considered “this,” “that,” and “here” as logical atoms or words for particulars.
• Structural Realism: According to William Demopolous and Michael Friedman, the heart of the theory of The Analysis of Matter is the claim that our knowledge of the external world is purely structural.
• Inference: R. M. Sainsbury writes about induction and Russell’s postulates, with HK (Human Knowledge) claiming that a priori knowledge of contingent propositions is needed to know anything other than our own data.

Russell’s Logical Atomism: Key Principles and Components

Russell’s logical atomism is a key component of his philosophical system, particularly prominent in his work from 1910-1913.

Key aspects of Russell’s logical atomism:

• Atomic Propositions and Facts: Logical atomism posits that the world is ultimately composed of simple, independent facts, mirroring the structure of language. These facts are atomic in that they cannot be broken down into simpler facts.
• Rejection of Single Entities: By 1913, Russell concluded that only particulars can be named, but facts cannot be named.
• Atomistic Hierarchy: Russell’s logical atomism determines what he describes as the atomistic hierarchy.
• Particulars as Logical Subjects: Russell’s ontology in 1910-11 included particulars, described as “ultimate dualism” of universals and particulars. He called the division of particulars as “objects” or complex single entities.
• Impact on Logical Syntax: Events from 1914 to 1940, were simple particulars of Russell’s atomist ontology, with ordinary physical objects being complex.
• Relation to acquaintance: Russell’s logical atomism includes the idea that we are “directly acquainted” with physical objects.
• Molecular Propositions: Molecular propositions are compounds of atomic propositions connected by logical connectives. The truth value of a molecular proposition is determined by the truth values of its constituent atomic propositions.

Russell’s “On Denoting”: Theory of Descriptions and Logical Form

Bertrand Russell’s “On Denoting,” published in 1905, marks a significant change in his philosophical views and is a crucial article in twentieth-century analytic philosophy.

Key aspects and significance of “On Denoting”:

• Shift in Ontological Commitment: According to Russell’s earlier views, to say that “the golden mountain does not exist” implies that the golden mountain has some kind of being. “On Denoting” allowed Russell to avoid the need for denoting concepts to correspond to objects.
• Theory of Descriptions: The theory of descriptions is applied by Russell not only to definite descriptions such as “the present king of France,” but also to ordinary proper names, such as “Aristotle” and “Mont Blanc”. The descriptive phrases associated with names are not necessarily analytic, and different speakers might associate different descriptive phrases with the same name.
• Elimination of entities: The theory of descriptions eliminates the need to assume that there are classes, or that we need to define objects or classes of classes.
• Generality: Russell introduces the theory of generality, holding it to be essential to logic and mathematics.
• Analysis and Logical Form: According to Peter Hylton, the significance of “On Denoting” lies in its emphasis on analysis and the development of logical form. The article represents a crucial step in the development of analytic philosophy. The grammatical form of a sentence can be misleading regarding its logical form.
• Denoting Concepts: Russell explains that a denoting concept is a term or combination of terms that may be connected with words and things through a relation. A proposition containing a denoting concept may be about things that it doesn’t contain.
• Incomplete Symbols: The notion of an incomplete symbol has an ontological significance, allowing for the elimination of classes.
• Problems and Puzzles: Russell’s reasons for developing the theory of denoting came from a passage of the preface of Principles. The theory helped him solve puzzles that arose from his attempt to reduce mathematics to logic.
• The King of France Example: The phrase “the present king of France” exemplifies how sentences containing denoting phrases can be meaningful even if the entity they seem to refer to does not exist. The proposition expressed by “The king of France is bald” does not contain the present king of France, but rather contains a denoting concept.
• Quantifiers and Variables: The theory explains how “any” is presupposed in mathematical formalism and elucidates the theory of the infinite.
• Critique of Meinong: Russell’s theory allows him to critique Meinong’s view that there is something that you are saying does not exist when you say that the golden mountain does not exist.
