by Kaufmann
[Front Matter and Preface]: The front matter and preface introduce Felix Kaufmann's work on the methodology of social sciences. Kaufmann explains that the book was influenced by John Dewey's 'Logic, the Theory of Inquiry', though he diverges from Dewey on the theory of meaning. He argues that methodology must be distinguished from deductive logic as an autonomous rational discipline. The preface also acknowledges various publishers and scholars who assisted in the book's development. [Table of Contents]: A comprehensive table of contents outlining the two-part structure of the book. Part I focuses on general methodology, covering topics like language, meaning, scientific rules, and causality. Part II applies these methodological principles to specific issues in the social sciences, including behaviorism, social facts, and economic theory. [Introduction: The Problem of Ground in Empirical Science]: The introduction establishes the 'pivotal issue of methodology' as the clarification of the meaning of 'ground' in empirical science. Kaufmann rejects the idea of infallible knowledge of facts and proposes that methodology should focus on the rules of scientific procedure and control. He argues that many methodological controversies in social science are actually rooted in general epistemological debates (e.g., rationalism vs. empiricism) and can be resolved by distinguishing between deductive reasoning and empirical procedure, as well as between analytic and synthetic propositions. [Knowledge and Reality: The Critique of the Copy Theory]: Kaufmann begins Part I by examining the distinction between action and perception, critiquing the 'copy theory' of knowledge which views perception as a passive reception of the world. He argues that sensory illusions and the instability of sense experience necessitate a search for invariant elements and universal principles of co-variation to distinguish objective reality from subjective phenomena. [The Role of Reason and the History of Methodological Thought]: This section traces the development of methodological thought from antiquity to Kant, focusing on the tension between the receptivity of sense and the spontaneity of reason. Kaufmann distinguishes between radical rationalism, which relies on pure conceptual analysis, and critical rationalism (or critical empiricism), exemplified by Galileo, which uses rational ideas as hypotheses to be tested by observation. [Primary and Secondary Qualities in the History of Science]: Kaufmann analyzes the historical distinction between primary (objective) and secondary (subjective) qualities, showing how it evolved from a metaphysical claim about 'true being' to a methodological tool for mathematical treatment. He discusses how Berkeley, Hume, and Kant eventually discarded the idea of primary qualities as exact likenesses of things-in-themselves, leading to the modern view of philosophy as the analysis of experience. [Meaning, Language, and the Structure of Propositions]: Kaufmann explores the relationship between linguistic signs and meanings, critiquing nominalist attempts to reduce meaning to language. He defines concepts and propositions as meanings independent of symbols and distinguishes between analytic and synthetic propositions. He also addresses the logical structure of thing-concepts and the debate between internal and external relations, referencing thinkers like Russell and Husserl. [Pre-scientific and Scientific Thinking: Continuity and Difference]: Kaufmann argues that there is no sharp line between pre-scientific and scientific thinking, as both rely on mental construction and perceptual material. He critiques the idea that science is purely quantitative or that measurement eliminates subjectivity, noting that mathematical formulae only gain physical significance when related to observable phenomena. He outlines seven fundamental properties of empirical procedure common to both modes of thought. [The Basic Rules of Scientific Procedure]: Kaufmann defines scientific procedure as the acceptance or elimination of propositions according to rules. He introduces the 'methodological principle of sufficient reason' and distinguishes between verification, invalidation, and falsification. He emphasizes the principle of permanent control—that no scientific proposition is exempt from future elimination—and discusses the role of protocol propositions (observation reports) as grounds for scientific decisions. [Consistency and Completeness in Procedural Rules]: Kaufmann defines a consistent system of procedural rules as one that prohibits simultaneous acceptance of incompatible propositions and mandates the elimination of conflicting ones. He introduces the procedural correlate of the principle of the excluded middle, defining a 'complete system' as one where no proposition is undecidable in all conceivable situations, making every proposition verifiable in principle. [The Principle of Determinacy and Quantum Physics]: The text examines the requirement of completeness in scientific procedure, specifically addressing whether Heisenberg's principle of indeterminacy invalidates the principle of the excluded middle. Kaufmann argues that the procedural correlate of the excluded middle is actually a principle of determinacy and critiques the historical confusion between deductive logic and the logic of scientific procedure dating back to Aristotle. [The Ideal of Truth and Permanent Control]: Kaufmann contrasts the principle of permanent control (the possibility of eliminating any proposition) with the procedural correlate of the excluded middle. He redefines 'truth' for synthetic propositions as an 'ideal of inquiry'—a goal defined by a potentially endless procedure of verification and control—distinguishing this from the theological notion of absolute truth or truth-in-itself. [Rationality, Skepticism, and Empirical Validity]: The author discusses the rationality of empirical procedure, arguing that while its rules are not 'ultimately rational' like deductive logic, the correctness of decisions within those rules is provable by reason. He addresses skepticism, noting that while synthetic propositions are never 'ultimately established' due to permanent control, this does not render the belief in truth inconsistent. He proposes the terms 'empirically valid' and 'empirically counter-valid' to avoid the ambiguities of the word 'truth'. [Goals of Science and Preference Rules]: This section distinguishes between non-theoretical goals (human welfare, personal security) and theoretical goals (answering pertinent questions) of scientific inquiry. Kaufmann defines 'problems' in science as the setting of theoretical goals, distinguishing between logical problems (explicating meaning) and empirical problems (verifying facts), and further categorizing problems by whether they have a limited or unlimited number of conceivable solutions. [Explanation and Prediction in Scientific Situations]: Kaufmann analyzes the logical and empirical components of explanation and prediction. He argues that explanation does not require a scientific decision if the laws and facts are already established in the corpus of science, but decisions are necessary when premises must be discovered or verified. He introduces a framework of four situations regarding the explanation of facts. [Classification of Explanations and the Nature of Solutions]: Kaufmann classifies four situations of scientific explanation based on whether laws or facts are established. He argues that the logical structure of explanation is identical to prediction and defines a 'solution' as the chain of steps leading to an answer, introducing the concept of relevance as a part of the solution rather than a teleological means. [Preference Rules and Presumable Relevance]: The author discusses how scientists choose between alternative approaches to unsolved problems using preference rules. He uses the example of infantile paralysis research to distinguish between presumably relevant and irrelevant data, arguing that methodological criticism is always relative to presupposed procedural rules. [Scientific Ideals and the Rational Cosmos]: Kaufmann outlines the theoretical ideals of 18th and 19th-century science influenced by Newtonian physics: Unity and Simplicity, Unrestricted Universality, Precision, and the Pervasiveness of Law (Determinism). He notes that these ideals serve as regulative principles for preference rules in scientific procedure. [Methodological Pluralism and the Interpretation of Ideals]: The author argues for methodological pluralism, especially in the social sciences, where different methods may coexist. He critiques aprioristic and subjective interpretations of scientific ideals, advocating for a Kantian view of ideals as regulative principles linked to preference rules. [Physical Laws and Causality: The Critique of Induction]: Kaufmann begins Chapter VI by distinguishing between synthetic universal propositions and rules of empirical procedure. He provides a detailed critique of Whately and Mill's 'principle of the uniformity of nature,' arguing that induction is actually a subsumption under procedural rules rather than a deduction from an ultimate major premise. [Theoretical vs. Empirical Laws and the Ceteris Paribus Clause]: Kaufmann distinguishes between empirical laws (falsifiable synthetic propositions) and theoretical laws (non-falsifiable rules of procedure). He explains the 'ceteris paribus' clause as a resolution to retain procedural rules despite failed predictions and discusses 'idealization' in the work of Galileo and Mach as a prescription for procedure rather than a description of an ideal world. [Conventionalism, Empiricism, and Quantum Physics]: The author mediates the conflict between conventionalists and empiricists by identifying their focus on theoretical and empirical laws, respectively. He examines how modern physics, specifically relativity and quantum mechanics, relates to scientific ideals, noting the shift from the continuous differential equations of classical physics to the statistical nature of quantum laws. [Foundations of Mathematics and Physical Space]: Kaufmann summarizes the 19th-century revolution in the foundations of mathematics, emphasizing that pure geometry is a system of propositional functions rather than absolute truths about reality. He discusses the transition from Euclidean to Riemannian geometry in physics as an empirical choice of descriptive framework. [The Logic of Causality and the Principle of Causality]: Kaufmann defines causality in terms of laws, distinguishing between basic causes (necessary conditions) and sufficient conditions. He critiques the notion of 'necessary' causal bonds, reinterpreting them as logical implications within a system of laws, and defines the 'principle of causality' as a methodological resolution to seek explanations. [Theories of Truth: Russell vs. Coherence]: Kaufmann critiques Bertrand Russell's correspondence theory of truth and his reliance on 'basic propositions' caused by sensible occurrences. He argues that the coherence theory (or warranted assertability) is more procedurally significant, as it defines truth in terms of rules of empirical procedure rather than a transcendent agreement with things-in-themselves. [Probability as Rational Belief: J.M. Keynes]: The author examines J.M. Keynes' theory of probability as a degree of rational belief. While critiquing Keynes' sensationalist premises, Kaufmann aligns Keynes' 'secondary propositions' with his own 'rules of procedure,' arguing that probability inference is the logical assessment of the correctness of scientific decisions based on evidence. [Degrees of Confirmation and Probability Preference]: Kaufmann defines 'degree of confirmation' (or probability) based on the extent to which a complete verifier is contained within a given scientific situation. He introduces 'rules of probability preference' to explain how scientists choose between incompatible undecided propositions as working hypotheses. [The Frequency Interpretation of Probability: Richard von Mises]: Kaufmann reviews Richard von Mises' frequency theory of probability, which defines probability as the limit of relative frequency in a 'collective.' He notes the mathematical nature of this theory and the paradox that statistical evidence from finite trials cannot strictly refute a probability statement about an infinite series. [Probability Indices and Reichenbach's Identity Conception]: The author discusses Hans Reichenbach's attempt to apply the frequency interpretation to single cases using the concept of 'weight.' Kaufmann argues that while statistical laws can provide 'probability indices,' these indices are not identical to the laws themselves but require additional rules of probability preference. He also critiques Reichenbach's infinite-valued probability logic. [The Vitalist Controversy: Mechanism vs. Vitalism]: Kaufmann analyzes the historical and methodological aspects of the vitalist controversy. He reviews arguments from biochemistry (Wöhler) and Hans Driesch's experiments on sea urchins (organic regulation). He argues that the conflict often stems from a confusion between the logical definition of 'life' and the empirical facts of biological processes. [Teleology and Functional Method in Biology]: The author critiques the vitalist use of 'purpose' and 'entelechy,' arguing that biological 'functions' can be described in causal terms without invoking conscious ends. He defines an 'organism' not as a morphological aggregate but as a field of application for biological laws, where components are functionally interrelated. [The Psycho-Physical Problem and Behaviorism]: Kaufmann examines the psycho-physical problem, categorizing theories into parallelism, causality, materialism, and spiritualism. He critiques behaviorism and Scheler's theory of immediate apprehension, arguing that knowledge of others involves interpreting physical data as symptoms of psycho-physical facts through specific procedural rules. [Value Judgments: Parallelism with Epistemology]: Kaufmann begins Chapter IX by drawing a parallel between epistemology and ethics, comparing sensations to feelings and truth to value. He traces the history of these ideas from the Sophists and Socratics through modern rationalism and empiricism, setting the stage for a logical analysis of value judgments. [The Logic of Value Judgments as Analytic Propositions]: The author presents his core thesis on values: value judgments are analytic propositions derived from presupposed axiological rules. He distinguishes between the factual properties of an object and the rules that assign value to those properties. He also discusses the 'objectivity' of values and the Socratic method as a process of clarifying and rectifying moral principles. [Part II: Methodological Issues in Social Science - The Naturalism Debate]: Kaufmann introduces the 'crisis' in the social sciences, characterized by dissatisfaction with their results compared to the natural sciences. He defines 'naturalism' as the doctrine that social sciences must adopt the methods of physics to be scientific, and 'anti-naturalism' as the rejection of this demand. The section outlines the arguments for naturalism, such as the success of hierarchical laws and mathematical precision, and the counter-arguments from anti-naturalists who cite human free will, the lack of experimental scale, and the historical specificity of social phenomena. [Arguments for Naturalism and Anti-Naturalism]: A detailed synopsis of the debate between naturalistic and anti-naturalistic theses. Naturalists argue that social sciences are currently deficient due to a lack of abstraction and intersubjective control, suggesting a reconstruction based on the model of physics. Anti-naturalists are divided into those who believe in social laws 'sui generis' (often based on introspection) and those who deny the existence of strict social laws entirely due to factors like human irrationality, the impossibility of large-scale experiments, and the value-laden nature of social inquiry. [Methodological Pluralism and the Role of Psychology]: Kaufmann argues against the assumption that there is only one 'true' method for any given subject. He cites C.L. Hull to illustrate the fragmentation within psychology and warns against false analogies, such as the 'organic' theory of the state. Using the history of art as an example (contrasting Wölfflin's problem-oriented approach with Burckhardt's synoptic 'spirit of the age' approach), he demonstrates that different methods can yield significant results depending on the researcher's specific theoretical or practical interests. [Chapter XI: Behaviorism and Introspectionism]: This chapter examines the conflict between behaviorism, which restricts inquiry to observable bodily behavior, and introspectionism, which relies on self-observation. Kaufmann analyzes the justifications for both: behaviorists argue that introspection is unreliable and non-testable, while introspectionists argue that human activity cannot be understood without internal insight. He critiques the aprioristic claims of both sides, noting that both often fall into the trap of intuitionism—the belief that isolated acts of experience provide ultimately valid knowledge. [Physicalism and the Logical Analysis of Meaning]: Kaufmann discusses the implications of the 'psychical' being accessible to only one person, referencing Hugo Münsterberg. He then examines 'physicalism' as the radical logical formulation of behaviorism, primarily through the work of Carnap and Hempel. The core thesis of early physicalism is that every confirmable psychological sentence is translatable into a physical sentence about spatio-temporal events. The segment concludes by defining 'control sentences' and the criteria for scientific meaning based on truth-conditions and observability. [Psychological Sentences and the Critique of Physicalism]: Kaufmann examines the physicalist argument that psychological sentences are merely abbreviated formulations of physical world descriptions. He critiques Carnap's earlier sensationalist doctrine and discusses the role of protocol propositions and self-observation in scientific psychology, arguing that indirect intersubjective control is possible even for subjective states. [Carnap's Revision and the Theory of Reduction Statements]: The segment analyzes Carnap's revised physicalism, where psychological terms are no longer identical to physical terms but are reducible to the 'thing-language' via behavioristic symptoms. Kaufmann argues that this attempt to eliminate psychological facts by reduction fails because the laws used for reduction presuppose the very terms they seek to eliminate. [The Nature of Social Collectivities: Universalism vs. Individualism]: Kaufmann explores the historical and philosophical debate between universalistic and individualistic conceptions of society. He critiques the use of the 'social contract' as a historical fact and warns against confounding genetic, logical, and axiological priority when defining the nature of social groups and institutions. [Defining Society and Social Action: Simmel and Weber]: This section defines 'society' and 'social action' by refining the theories of Simmel and Max Weber. Kaufmann introduces the concept of a 'scheme of interpretation' (Deutungsschema) to explain social relationships as predictable patterns of behavior based on subjective meanings and motives. [Legal Persons, Social Wholes, and Political Creeds]: Kaufmann analyzes the concept of the 'legal person' and the methodological implications of universalist versus individualist doctrines. He argues that political creeds (like democracy or organicism) cannot be logically deduced from sociological definitions, as such justifications often conflate logical analysis with evaluation. [The Interpretation of Social Facts and Signs]: Kaufmann discusses the dimensions of interpreting social facts, emphasizing that social actions and institutions are not directly observable physical facts but require a 'fundamental interpretation.' He distinguishes between the objective meaning of signs (conventional rules) and subjective meaning (intended communication). [Determinism, Free Will, and Methodological Resolutions]: Kaufmann examines the debate between deterministic and indeterministic views of human action. He lists nine different theses on 'free will' and their methodological applications, concluding that these are often expressions of methodological resolutions rather than controllable scientific assertions. [Comparison of Natural and Social Laws: Ideals of Science]: Kaufmann compares the 'perfection' of laws in natural and social sciences using ideals like unity, universality, precision, and pervasiveness. He critiques the Neo-Kantian distinction between nomothetic and idiographic sciences, arguing that the differences are of degree and complexity rather than fundamental nature. [The Sociology of Knowledge and Objectivity]: Kaufmann reviews the history and claims of the sociology of knowledge, focusing on Karl Mannheim's work. He examines the thesis that social situations condition the 'perspective of thought' and discusses the tension between situational determination and the ideal of objective truth. [Critique of Mannheim: Validity vs. Existence]: Kaufmann critiques Mannheim's 'relationalism,' arguing that while social factors influence the *genesis* of knowledge, they do not enter into the *definition* of validity or truth. He maintains that scientific truth is defined by rules of procedure that remain independent of the scientist's social setting. [Objectivity in Historiography and Causal Imputation]: Kaufmann applies his analysis of objectivity to historical science, discussing how historians select 'relevant' facts. He argues that historical causes are established through interpretation in terms of laws, and that different historical 'perspectives' are often just different problems rather than incompatible truths. [Value Problems and Ethical Neutrality]: Kaufmann discusses the role of values in social science, supporting Max Weber's demand for ethical neutrality. He argues that value judgments are analytic propositions when their underlying axiological rules are made explicit, and that science can analyze the means and consequences of values without validating the ultimate ends themselves. [Teleology, Norms, and the Pure Theory of Law]: Kaufmann examines the use of teleological and normative methods in social science, with a focus on Hans Kelsen's Pure Theory of Law. He critiques the 'is/ought' dualism as an ontological claim, instead treating norms as analytic definitions within a legal order, and discusses Rickert's 'relation to values' in history. [The Foundations of Economic Theory and the Profit Motive]: Kaufmann analyzes the methodological foundations of classical economics. He argues that fundamental market laws (like the law of demand) are not empirical laws falsifiable by single instances but are theoretical laws that guide inquiry and explanation through the use of 'ceteris paribus' clauses. [Rational Action and the Problem of Perfect Foresight]: This segment critiques the concept of 'perfect foresight' in economic models of rational behavior, such as Cournot's monopoly theory. Kaufmann proposes replacing 'perfect foresight' with 'warranted prediction' based on available scientific knowledge and rules of procedure. [Marginal Utility and the Measurability of Value]: Kaufmann explains the marginal utility principle as a definition of rational economic behavior and a program for research. He addresses the controversy over the measurability of utility, arguing that while direct measurement is impossible, indirect measurement via correlated indicators is logically permissible. [Ludwig von Mises and the Aprioristic Thesis in Economics]: Kaufmann critiques Ludwig von Mises' aprioristic view of economics. He argues that while Mises' derivations from the 'category of action' are logically consistent, they are analytic propositions that cannot yield synthetic knowledge about reality without empirical conditions. [Summary and Conclusions: Principles of Scientific Procedure]: Kaufmann synthesizes his methodology, defining scientific procedure as the set of rules for incorporating or eliminating propositions from a science. He distinguishes between deductive logic, which concerns internal relations of meanings, and the logic of scientific procedure (methodology), which defines correct scientific decisions. He outlines fundamental principles such as the reversibility of decisions, the key role of observational reports, and the procedural correlates of contradiction and the excluded middle. He further clarifies that truth in science is defined by rules of verification and invalidation rather than immediate experience. [Summary and Conclusions: Laws, Causality, and Probability]: This section distinguishes between empirical laws (synthetic universal propositions) and theoretical laws (procedural rules). Kaufmann analyzes the concept of causality, following Hume in viewing causal relations as external but adding a logical analysis of the procedural rules involved. He addresses the principle of causality as a methodological resolution rather than a law. Probability is discussed in two senses: the frequency interpretation in statistics and the 'weight of evidence' for hypotheses. Finally, he applies these distinctions to the relationship between biology, psychology, and physics, critiquing both mechanist and vitalist positions. [Summary and Conclusions: Value Theory and Social Science Methodology]: Kaufmann explores the correspondence between the theory of knowledge and value theory, arguing that value judgments are analytic propositions relative to a system of axiological rules. He critiques the traditional fact-value dichotomy, reframing it as a distinction between procedural and axiological rules. Turning to social science, he addresses the behaviorism-introspection debate, the work of Max Weber, and the status of social laws. He argues that the 'subjectivity' of social science is a misunderstanding of the rules of empirical procedure and that value judgments, when clearly defined, are admissible as analytic components of social theory. [Summary and Conclusions: Philosophical Implications and Scientific Cooperation]: The author situates his methodology within broader philosophical debates, critiquing extreme versions of rationalism, empiricism, realism, and idealism. He emphasizes that methodology clarifies the meaning of 'empirical science' and is essential for the advancement of knowledge, especially in social research where laws are often implicit. He discusses the necessity of scientific cooperation and the constructive role of criticism. The section concludes by asserting that methodology promotes mutual understanding among scientists and provides a foundation for argument that resists the 'argument of power.' [Final Remarks and Methodological Function]: A brief concluding statement on the social and scientific function of methodology. Kaufmann argues that methodology is not merely an academic exercise but a tool for promoting understanding and the power of rational argument over force. [Notes to Chapters I-XVII]: Comprehensive endnotes for the entire volume. Includes citations and elaborations on key figures such as Plato, Galileo, Newton, Locke, Husserl, Dewey, and Leibniz. Covers topics from the history of physical laws and mathematical logic to the sociology of knowledge, legal theory (Kelsen), and economic postulates (marginal utility school).

He then examines 'physicalism' as the radical logical formulation of behaviorism, primarily through the work of Carnap and Hempel. The core thesis of early physicalism is that every confirmable psychological sentence is translatable into a physical sentence about spatio-temporal events. The segment concludes by defining 'control sentences' and the criteria for scientific meaning based on truth-conditions and observability.
Read full textKaufmann examines the physicalist argument that psychological sentences are merely abbreviated formulations of physical world descriptions. He critiques Carnap's earlier sensationalist doctrine and discusses the role of protocol propositions and self-observation in scientific psychology, arguing that indirect intersubjective control is possible even for subjective states.
Read full textThe segment analyzes Carnap's revised physicalism, where psychological terms are no longer identical to physical terms but are reducible to the 'thing-language' via behavioristic symptoms. Kaufmann argues that this attempt to eliminate psychological facts by reduction fails because the laws used for reduction presuppose the very terms they seek to eliminate.
Read full textKaufmann explores the historical and philosophical debate between universalistic and individualistic conceptions of society. He critiques the use of the 'social contract' as a historical fact and warns against confounding genetic, logical, and axiological priority when defining the nature of social groups and institutions.
Read full textThis section defines 'society' and 'social action' by refining the theories of Simmel and Max Weber. Kaufmann introduces the concept of a 'scheme of interpretation' (Deutungsschema) to explain social relationships as predictable patterns of behavior based on subjective meanings and motives.
Read full textKaufmann analyzes the concept of the 'legal person' and the methodological implications of universalist versus individualist doctrines. He argues that political creeds (like democracy or organicism) cannot be logically deduced from sociological definitions, as such justifications often conflate logical analysis with evaluation.
Read full textKaufmann discusses the dimensions of interpreting social facts, emphasizing that social actions and institutions are not directly observable physical facts but require a 'fundamental interpretation.' He distinguishes between the objective meaning of signs (conventional rules) and subjective meaning (intended communication).
Read full textKaufmann examines the debate between deterministic and indeterministic views of human action. He lists nine different theses on 'free will' and their methodological applications, concluding that these are often expressions of methodological resolutions rather than controllable scientific assertions.
Read full textKaufmann compares the 'perfection' of laws in natural and social sciences using ideals like unity, universality, precision, and pervasiveness. He critiques the Neo-Kantian distinction between nomothetic and idiographic sciences, arguing that the differences are of degree and complexity rather than fundamental nature.
Read full textKaufmann reviews the history and claims of the sociology of knowledge, focusing on Karl Mannheim's work. He examines the thesis that social situations condition the 'perspective of thought' and discusses the tension between situational determination and the ideal of objective truth.
Read full textKaufmann critiques Mannheim's 'relationalism,' arguing that while social factors influence the *genesis* of knowledge, they do not enter into the *definition* of validity or truth. He maintains that scientific truth is defined by rules of procedure that remain independent of the scientist's social setting.
Read full textKaufmann applies his analysis of objectivity to historical science, discussing how historians select 'relevant' facts. He argues that historical causes are established through interpretation in terms of laws, and that different historical 'perspectives' are often just different problems rather than incompatible truths.
Read full textKaufmann discusses the role of values in social science, supporting Max Weber's demand for ethical neutrality. He argues that value judgments are analytic propositions when their underlying axiological rules are made explicit, and that science can analyze the means and consequences of values without validating the ultimate ends themselves.
Read full textKaufmann examines the use of teleological and normative methods in social science, with a focus on Hans Kelsen's Pure Theory of Law. He critiques the 'is/ought' dualism as an ontological claim, instead treating norms as analytic definitions within a legal order, and discusses Rickert's 'relation to values' in history.
Read full textKaufmann analyzes the methodological foundations of classical economics. He argues that fundamental market laws (like the law of demand) are not empirical laws falsifiable by single instances but are theoretical laws that guide inquiry and explanation through the use of 'ceteris paribus' clauses.
Read full textThis segment critiques the concept of 'perfect foresight' in economic models of rational behavior, such as Cournot's monopoly theory. Kaufmann proposes replacing 'perfect foresight' with 'warranted prediction' based on available scientific knowledge and rules of procedure.
Read full textKaufmann explains the marginal utility principle as a definition of rational economic behavior and a program for research. He addresses the controversy over the measurability of utility, arguing that while direct measurement is impossible, indirect measurement via correlated indicators is logically permissible.
Read full textKaufmann critiques Ludwig von Mises' aprioristic view of economics. He argues that while Mises' derivations from the 'category of action' are logically consistent, they are analytic propositions that cannot yield synthetic knowledge about reality without empirical conditions.
Read full textKaufmann synthesizes his methodology, defining scientific procedure as the set of rules for incorporating or eliminating propositions from a science. He distinguishes between deductive logic, which concerns internal relations of meanings, and the logic of scientific procedure (methodology), which defines correct scientific decisions. He outlines fundamental principles such as the reversibility of decisions, the key role of observational reports, and the procedural correlates of contradiction and the excluded middle. He further clarifies that truth in science is defined by rules of verification and invalidation rather than immediate experience.
Read full textThis section distinguishes between empirical laws (synthetic universal propositions) and theoretical laws (procedural rules). Kaufmann analyzes the concept of causality, following Hume in viewing causal relations as external but adding a logical analysis of the procedural rules involved. He addresses the principle of causality as a methodological resolution rather than a law. Probability is discussed in two senses: the frequency interpretation in statistics and the 'weight of evidence' for hypotheses. Finally, he applies these distinctions to the relationship between biology, psychology, and physics, critiquing both mechanist and vitalist positions.
Read full textKaufmann explores the correspondence between the theory of knowledge and value theory, arguing that value judgments are analytic propositions relative to a system of axiological rules. He critiques the traditional fact-value dichotomy, reframing it as a distinction between procedural and axiological rules. Turning to social science, he addresses the behaviorism-introspection debate, the work of Max Weber, and the status of social laws. He argues that the 'subjectivity' of social science is a misunderstanding of the rules of empirical procedure and that value judgments, when clearly defined, are admissible as analytic components of social theory.
Read full textThe author situates his methodology within broader philosophical debates, critiquing extreme versions of rationalism, empiricism, realism, and idealism. He emphasizes that methodology clarifies the meaning of 'empirical science' and is essential for the advancement of knowledge, especially in social research where laws are often implicit. He discusses the necessity of scientific cooperation and the constructive role of criticism. The section concludes by asserting that methodology promotes mutual understanding among scientists and provides a foundation for argument that resists the 'argument of power.'
Read full textA brief concluding statement on the social and scientific function of methodology. Kaufmann argues that methodology is not merely an academic exercise but a tool for promoting understanding and the power of rational argument over force.
