Manhood of Humanity: The Science and Art of Human Engineering was written by the famous Polish-American philosopher and scientist, Alfred Korzybski. Best known for his work developing the theory of "general semantics," Korzybski dedicated his life to mapping out the operations performed by the human brain. In this book, Korzybski presents an engaging and thought provoking look at his philosophical views of humanity and the human condition.

Korzybski passed away before the publication of this edition of the book so the editor decided to dedicate the first chapter to him, and provides a biography of the author. The book then delves into Korzybski's philosophy, discussing the root of humanity and how it is fostered in children at a very young age. Korzybski explores how wealth, capitalism, elements of power, and the ideas of "survival of the fittest" affect humanity as we know it. The book also contains multiple appendices that include further information on the topics explored within the text for readers to enjoy at their leisure. Korzybski's primary goal with the text is to imbue readers with a passion for the topic, to enlighten them and provoke them to action—to bring back humanity as we knew it prior to greed and feelings of inherent superiority.

Alfred Korzybski's book Manhood of Humanity: The Science and Art of Human Engineering is a wonderful exploration of what it means to be human. This is an entertaining and enlightening book that represents that deepest thoughts and values of the author. Korzybski's plea to the reader who enjoys this text is to enact change in society when possible—to help their fellow man return to a kinder and gentler state.
