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.
