This book is intended as a brief introduction to the study of the human mind. In writing it, I have tried to anticipate and to remove some of the difficulties which are usually felt by students on taking up the subject for the first time. The illustrations are largely drawn from everyday experiences and familiar books. The use of technical terms has been avoided as far as possible. Where they occur, they are explained in the text, and referred to in the index by a different type. The index thus, to some extent, serves the purpose of a glossary. Those readers who do not know any logic, may find it advisable to begin the book at the second chapter, and to leave the first until they have read the account of logical processes given in the chapter on Reasoning.
I am indebted to Prof. Symes for some useful hints, and to Mr. J. W. Carr, M.A. for revising the proofs from page 65 to the end.
