This book presents a cognitive reading of man from a scientific point of view, not a philosophical one. Dr. Alexis Marel is not a philosopher, but rather a man of science. He spent the greater part of his life in the laboratory studying living organisms, and the remaining part in the vast world observing human beings and trying to understand them. The importance of his experience lies in it being a summary of the observations and experiments that he saw with his own eyes or as a result of direct knowledge from those with whom he came into contact.
