Herbert Spencer

Spencer, Herbert - 1820–1903, English philosopher, b. Derby. He projected a vast 10-volume work, Synthetic Philosophy, in which all phenomena are interpreted according to the principle of evolutionary progress. Together with Charles Darwin and Thomas Huxley he was responsible for the acceptance of the theory of evolution. In First Principles (1862), the first of the projected volumes, Spencer distinguished phenomena from what he called the unknowable—an incomprehensible power or force from which everything derives. He limited knowledge to phenomena, i.e., the manifestations of the unknowable. He maintained that these manifestations proceed from their source according to a process of evolution. In The Principles of Biology (2 vol., 1864–67) and The Principles of Psychology (1855; rev. ed., 2 vol., 1870–72) Spencer gave a mechanistic explanation of how life has progressed by the continual adaptation of inner relations to outer ones. In The Principles of Sociology (3 vol., 1876–96) he analyzed the process by which the individual becomes differentiated from the group and gains increasing freedom. In The Principles of Ethics (2 vol., 1879–93) he developed a utilitarian system in which morality and survival are linked. Spencer's synthetic system had more popular appeal than scientific influence, but it served to bring the doctrines of evolution within the grasp of the general reading public and to establish sociology as a discipline. His Autobiography was published in 1904.
