Henry Sidgwick (1838-1900), English philosopher and educator is today most famous for his Methods of Ethics first published in 1874 and considered by C. D. Broad among others to be the greatest single work on ethics in English.

Besides philosophy, Sidgwick wrote on education, literature, political theory, the history of political institutions, and psychical research. He was also active in University politics, economics and administration, playing a large part in the founding of the first College for women - Newnham College, Cambridge. Although Methods of Ethics is considered the most valuable of his writings - reprinted here in its first and last editions - his intellect is displayed in the full extent of his writings. Professor Marshall said in reference to his discussions of the proper functions of government in Principles of Political Economy that it was 'by far the best thing of the kind in any language'. In all his writings, Sidgwick is rigorous and cautious, reluctant to advance ideas without making sure of his ground. In common with Mill he was opposed to mystical and transcendental methods.

This comprehensive collection brings together the most definitive editions of all his books and includes the standard biography written by his wife, as well as two volumes of previously uncollected essays and reviews.
