Lloyd Morgan's theory of instinct: from Darwinism to neo-Darwinism.
Darwin's proposal of two sources of instinct--natural selection and inherited habit--fostered among late nineteenth century evolutionists a variety of conflicting notions concerning the mechanisms of evolution. The British comparative psychologist C. Lloyd Morgan was a cardinal figure in restructuring the orthodox Darwinian conception to relieve the confusion besetting it and to meet the demands of the new biology of Weismann. This paper traces the development of Morgan's ideas about instinct against the background of his philosophic assumptions and the views of instinct theorists from Darwin and Romanes to McDougall and Lorenz.
