Genius is a fascinating topic. Everyone has an opinion on it, but not a lot of clarity. Much has been written on the subject - biographies, autobiographies, technical books, popular science books, and practical manuals - but genius in all of its dimensions has yet to be addressed. This book seeks to remedy that. What follows is a work of significant breadth that hopes to facilitate a nuanced popular understanding of the definition of genius, examining all of the main theories and approaches regarding the nature and origin of brilliance, the cognitive path that geniuses follow, and the difference that exists between geniuses on one side and normal people on the other. Pragmatic indications surrounding this issue are also examined, regarding such questions as: is it possible to become a genius or is genius innate? If it is possible, what is the path - no doubt long and difficult - that one must take? Is there a method for becoming a genius that can be taught and learned? This book will appeal to anyone who has ever contemplated great ideas and works and wondered how they came into being.
