This book, sure to become a standard reference work, is a comprehensive, lucid, and systematic commentary on Kant's practical (or moral) philosophy. Kant is arguably the most important moral philosopher of the modern period. Using as nontechnical a language as possible, Professor Sullivan offers a detailed, authoritative account of Kant's moral philosophy - including his ethical theory, his philosophy of history, his political philosophy, his philosophy of religion, and his philosophy of education - and demonstrates the historical, Kantian origins of such important notions as 'autonomy', 'respect for persons', 'rights', and 'duties'. An invaluable resource, this book will be extremely useful to advanced undergraduates, graduates, and professional philosophers alike.
