Mill’s System of Logic is one of the foundational texts of nineteenth-century philosophy and scientific method, setting out his theory of induction and codifying the principles that became known as “Mill’s Methods”. It exerted enormous influence on Victorian thought, particularly in the development of empiricism, the philosophy of science, and the emerging social sciences. A first edition set of an important philosophical work.
