The relation between body and mind is one of the oldest riddles that has puzzled mankind. Physical and chemical processes may act upon the mind; and when we are writing a difficult letter, our mind acts upon our body and, through a chain of physical events, upon the mind of the recipient of the letter. The authors of this book stress that they cannot solve the body mind problem; but they hope that they have been able to shed new light on it. Inscribed on title page by author John C. Eccles.
