Carnap's 1966 'Philosophical Foundations of Physics' — accessible late synthesis of his philosophy of physics
Published by Basic Books in 1966 (edited from Carnap's UCLA lectures by Martin Gardner — the renowned popular-scientific writer who had been Carnap's graduate student), 'Philosophical Foundations of Physics: An Introduction to the Philosophy of Science' is Carnap's accessible late synthesis of his philosophy of physics. Carnap had moved to UCLA in 1954 after his Chicago years (1936-52, with a brief 1952-54 stint at the Institute for Advanced Study at Princeton); the book grew out of his teaching there in the late 1950s and early 1960s. Across 28 chapters in six parts, the book treats: (Part I) Laws, Explanation, and Probability — the logic of scientific laws, the deductive-nomological model of explanation (Hempel-Oppenheim, which Carnap had developed with Hempel in the 1940s), the philosophical interpretation of probability; (Part II) Measurement and Quantitative Language — the foundations of measurement theory; (Part III) The Structure of Space — the philosophical foundations of geometry, Einstein's general relativity, the conventionalist-realist debate (Poincaré, Reichenbach, Grünbaum) about whether geometry is conventional or empirical; (Part IV) Causality and Determinism — the deterministic-probabilistic distinction, Hume's critique of necessary connection, the place of statistical-thermodynamic and quantum-mechanical reasoning; (Part V) Theoretical Laws and Theoretical Concepts — the observational-theoretical distinction (which Carnap had famously developed in the 1930s-50s), the Ramsey-Carnap programme for the elimination of theoretical terms, the empirical interpretation of physical theory; (Part VI) Beyond Determinism — Carnap's mature treatment of the philosophical implications of quantum mechanics. The book is one of the most accessible Carnap publications and remains a standard introduction to mid-twentieth-century logical-empiricist philosophy of science.

Internal Tensions
Standard accessible mid-twentieth-century logical-empiricist philosophy of physics. Continuously used in graduate-level philosophy-of-science teaching; the most accessible Carnap text; the synthesis of his lifelong positions in a readable single volume.
I. Time
1966 publication. Carnap was 75, four years before his 1970 death.
Attributes
II. Space
UCLA — Carnap's institutional base since 1954 (he had moved from Chicago).
Attributes
III. Matter
Lecture-derived book (~300 pages). Form is accessible philosophical-pedagogical: each chapter develops one topic in the philosophy of physics with attention to the empirical-scientific examples.
Attributes
IV. Observer
Late Carnap. The observer-philosopher is the senior surviving member of the Vienna Circle and the leading living logical-empiricist philosopher of science.
Attributes
V. Energy
Late-pedagogical philosophy-of-science energies. The book consolidates and presents Carnap's mature philosophical-scientific positions accessibly.
Attributes
VI. Information
Single book across six parts. The treatment of space (Part III) and of theoretical concepts (Part V) is the most philosophically dense material.
