ABSTRACT
This chapter provides considerable attention to the continuing importance and relevance of John Stuart Mill ideas on the logic of the social sciences and, particularly, psychology and ethology. The idea of seeing Mill and Bain as a "double helix" may seem preposterous to many philosophers and intellectual historians today who prefer a more individual approach to their subjects. Alternatively, they prefer various collective schools, from utilitarianism to idealism or to Marxism. Bentham was notorious for sharing the writing and publication of his work with a number of important figures from Etienne Dumont to both James and John Stuart Mill. But Bentham remained the source of the ideas and inspiration for their development, even though others may have done a good deal of the work in producing the actual texts. The relationship between Mill and Bain as a double helix proceeded almost from the outset, and from this double helix the development of modern social science was considerably enhanced.
