Volume 1

A fellow of Trinity College, Cambridge, and of the Royal Society, William Clifford (1845-79) made his reputation in applied mathematics, but his interests ranged far more widely, encompassing ethics, evolution, metaphysics and philosophy of mind. This posthumously collected two-volume work, first published in 1879, bears witness to the dexterity and eclecticism of this Victorian thinker, whose commitment to the most abstract principles of mathematics and the most concrete details of human experience resulted in vivid and often unexpected arguments. Volume 1 includes a detailed biographical introduction by Clifford's colleague, Frederick Pollock, who situates his close friend's interests in Darwin and Spinoza within a larger, life-long devotion to the principles of scientific enquiry and experiment. This volume also features two important essays, 'On Some of the Conditions of Mental Development', his first public lecture delivered at the Royal Institute in London, and 'The Philosophy of the Pure Sciences'.

Volume 2

A fellow of Trinity College, Cambridge, and of the Royal Society, William Clifford (1845-79) made his reputation in applied mathematics, but his interests ranged far more widely, encompassing ethics, evolution, metaphysics and philosophy of mind. This posthumously collected two-volume work, first published in 1879, bears witness to the dexterity and eclecticism of this Victorian thinker, whose commitment to the most abstract principles of mathematics and the most concrete details of human experience resulted in vivid and often unexpected arguments. Volume 2 shows Clifford's thorough engagement with scientific thought as a method for illuminating ethical and moral questions. Essays such as 'Body and Mind', 'On the Scientific Basis of Morals' and 'The Ethics of Belief' all variously demonstrate Clifford's core tenet: that beliefs - whether they guide human action or scientific enquiry - 'can never suffer from investigation'.

This posthumously collected two-volume work, first published in 1879, bears witness to the dexterity and eclecticism of this Victorian thinker, whose commitment to the most abstract principles of mathematics and the most concrete details of human experience resulted in vivid and often unexpected arguments. Edited by Leslie Stephen and Frederick Pollock (a close friend and colleague), the essays show Clifford's thorough engagement with scientific thought as a method for illuminating ethical and moral questions. They include 'On Some of the Conditions of Mental Development', 'On the Scientific Basis of Morals' and 'The Ethics of Belief'. Pollock also supplied a biography which focuses on Clifford's devotion to the principles of scientific enquiry and experiment.
