This two-volume work,first published in 1843,was John Stuart Mill's first major book.It reinvented the modern study of logic and laid the foundations for his later work in the areas of political economy,women's rights and representative government.In clear,systematic prose,Mill (1806 73) disentangles syllogistic logic from its origins in Aristotle and scholasticism and grounds it instead in processes of inductive reasoning.An important attempt at integrating empiricism within a more general theory of human knowledge,the work constitutes essential reading for anyone seeking a full understanding of Mill's thought.Volume 1 contains Mill's introduction,which elaborates upon his definition of logic as 'not the science of Belief,but the science of Proof,or Evidence'.It also discusses methods of logical reasoning propositions and syllogisms.Volume 2 contains 'On the Logic of the Moral Sciences',in which Mills applies empirical reasoning to human behaviour.
