This book analyses Kant’s assumptions about happiness and the implications they have for his moral, political, and legal thought. It provides a “map” of the different areas in which the concept of happiness appears in his practical philosophy and examines how it relates to the main themes of his practical philosophy.

Kant is often portrayed as the author of a rigid system of ethics in which adherence to a formal and universal principle of morality - the famous categorical imperative - is an end itself, and any concern for human goals and happiness a strictly secondary and subordinate matter. Such a theory seems to suit perfectly rational beings but not human beings. The twelve essays in this collection by one of the world's preeminent Kant scholars argue for a radically different account of Kant's ethics. They explore an interpretation of the moral philosophy according to which freedom is the fundamental end of human action, but an end that can only be preserved and promoted by adherence to moral law. By radically revising the traditional interpretation of Kant's moral and political philosophy and by showing how Kant's coherent liberalism can guide us in current debates, Paul Guyer will find an audience across moral and political philosophy, intellectual history, and political science.

This 1788 work, based on belief in the immortality of the soul, established Kant as a vindicator of the truth of Christianity. It offers the most complete statement of his theory of free will.

This volume of new essays provides a comprehensive and structured examination of Kant's justification of norms, a crucial but neglected theme in Kantian practical philosophy. The essays engage with the view that a successful account of justification of normative claims has to be non-metaphysical and go on to pursue further implications in ethics, legal and political philosophy, and philosophy of religion.

This book deals with good, evil, happiness and morally enhanced post-humans. It offers a succinct historical elaboration of philosophical stances towards morality and happiness, focusing on Kant's ideas in particular. Human augmented ethical maturity in a futuristic version of Kant’s Ethical Commonwealth implies, among else, voluntary moral bio-enhancement (VMBE); consequently, more happiness – as morality and happiness are in a circularly supportive relationship; ultimate morality (UM). UM is in its own way a universal morality. In line with the contention that Kant’s vision of the (not immediate but more distant) future of humanity is one of a cosmopolitan moral order in which humans act virtuously in the broadest possible community, that is, humanity, it is justified to conclude that successful VMBE is conducive to Kant’s vision. In this context the book is of great interest to a broad audience, such as those interested in VMBE and novel conceptions of morality, and those with an interest in the historical development of morality and happiness, in philosophy (specifically, ethics) and in post-humanity.

This book offers a comprehensive account of Kant's practical philosophy that highlights the unity across its disparate themes.

This book joins the contemporary recovery of Kant’s empirical works to highlight the relevance of his concept of culture for understanding the sources of various characteristic modern dilemmas, such as the tension between culture and happiness, the morally ambivalent nature of cultural progress, or the existing conflicts between a factual plurality of cultures and the historical forces pressing toward a universal civilization. The book will be of special interest for Kantian scholars, moral and political philosophers, as well as philosophers of culture.
