The Oxford Companion to Philosophy Part 103. The book is alphabetized by the whole headings of entries, as distinct from the first word of a heading.

At the end of the book there is also a useful appendix on Logical Symbols as well as the appendices A Chronological Table of Philosophy and Maps of Philosophy. | 1000 Chronological Table Ramsey 1903-30 Broad 1887-1971 publishes The Mind and its Place in Nature 1925 Five Types of Ethical Theory 1930 Heidegger 1889-1976 publishes Sein und Zeit 1927 Whitehead 1861-1947 publishes Process and Reality 1929 Carnap 1891-1970 publishes Der Logische Aufbau der Welt 1928 The Unity of Science 1932 Meaning and Necessity 1947 Logical Foundations of Probability 1950 Gödel 1906-78 publishes his incompleteness theorems 1931 Maritain 1882-1973 Jaspers 1883-1969 Bachelard 1884-1962 Marcel 1889-1973 Reichenbach 1891-1953 H.
