The ideas of C. D. Broad have affected the work of moral philosophers throughout the twentieth century to the present day. First published in 1971, this edited volume contains Broad’s best essays on the philosophical problems of Ethics, mostly written and published between 1914 and 1964. Among the essays are Broad’s important critiques of G. E. Moore’s ethical theory, his lecture entitled ‘Determinism, Indeterminism and Libertarianism’, and other pieces discussing topics as broad as Conscience, Egoism and Free Will. This reissue serves as an important companion to Broad’s other works, a number of which have also been reissued within the Routledge Library Editions series, and will be invaluable to students interested in Broad’s theories and twentieth-century philosophical thought.
