"Immanuel Kant's moral philosophy is one of the most distinctive achievements of the European Enlightenment. At its heart lies what Kant called the "strange thing": the free rational human will. This introduction explores the basis of Kant's anti-naturalist, secular, moral vision of the human good. Moving from a sketch of the Kantian will, with all its component parts and attributes, to Kant's canonical arguments for this categorical imperative, it shows why Kant thought his moral law the best summary expression of both his own philosophical work on morality and his readers' deepest shared convictions about the good. Kant's central tenets, key arguments, and core values are presented in an accessible and engaging way, making this book ideal for anyone eager to explore the fundamentals of Kant's moral philosophy." -- Back Cover
