if it were rather a continuation than the complement, many would be pleased,
for the exposition already made practically guarantees a rich application,
were it undertaken, to matters still further "away" in the realm of thought.
The present volume lacks the multitude of scientific data and references
which make "Mind in Evolution" so important for the study of psychology (as
behavior or not as behavior, as the reader pleases), but it contains in
their space many timely discussions, in some cases seemingly prophetic, of
teleology in its relation to evolution.

The seventeen chapters of the book (there is also an extremely thoughtful
Introduction and a full Index), are divided into two parts, one entitled
"Lines of Development" and the other "The Conditions of Development." The
reviewer's lazy cortex, and possibly those of other and more leisurely

view regards Mind as an organ evolved to adapt behavior to the environment,
(2) and tends to reduce its action to a mechanical process. (3) Parallelism

these depends the final interpretation of the recorded movement.

"II. The Structure of Mind. (1) Mental operations are known in the first
instance as objects of consciousness. (2) Mind is the permanent unity
