The Principles of Psychology, Part IV, Chapter ix, par. 219. Rudolf Steiner consulted the German edition, translated by Dr. B. Vetter and published at Stuttgart, 1882. Spencer, born 1820, an engineer by training, sought to explain "the phenomena of life, mind and society in terms of matter, motion and force." At first strongly influenced by Coleridge, Spencer placed evolution as the first and most universal principle, influencing all the sciences. To him, evolution was synonymous with progress. In his later development, Spencer championed rugged individualism, and became an outspoken opponent of socialism, upholding what he considered the absolute rights of private enterprise against any form of governmental control. Before his death in 1903, Spencer's optimistic view of human progress collapsed, and he fell prey to marked pessimism regarding the future of mankind.
