THE COMPARATIVE PSYCHOLOGY OF MAN.

[_Originally read before the Anthropological Institute, and
afterwards published in _Mind, _for January,_ 1876.]

While discussing with two members of the Anthropological Institute the
work to be undertaken by its psychological section, I made certain
suggestions which they requested me to put in writing. When reminded,
some months after, of the promise I had made to do this, I failed to
recall the particular suggestions referred to; but in the endeavour to
remember them, I was led to glance over the whole subject of comparative
human psychology. Hence resulted the following paper.

That making a general survey is useful as a preliminary to deliberate
study, either of a whole or of any part, scarcely needs showing.
Vagueness of thought accompanies the wandering about in a region without
known bounds or landmarks. Attention devoted to some portion of a
subject in ignorance of its connexion with the rest, leads to untrue
conceptions. The whole cannot be rightly conceived without some
knowledge of the parts; and no part can be rightly conceived out of
relation to the whole.

To map out the Comparative Psychology of Man must also conduce to the
more methodic carrying on of inquiries. In this, as in other things,
division of labour will facilitate progress; and that there may be
division of labour, the work itself must be systematically divided.

We may conveniently separate the entire subject into three main
divisions, and may arrange them in the order of increasing speciality.

The first division will treat of the degrees of mental evolution of
different human types, generally considered: taking account of both the
mass of mental manifestation and the complexity of mental manifestation.
This division will include the relations of these characters to physical
characters--the bodily mass and structure, and the cerebral mass and
structure. It will also include inquiries concerning the time taken in
completing mental evolution, and the time during which adult mental
power lasts; as well as certain most general traits of mental action,
such as the greater or less persisten
