is apt to be
isolated--this is due to the very form of the enquiry; whereas, in
truth, it is indistinguishable from circumstances, the very language
which it uses being the result of the instincts of long-forgotten
generations, and every word which a man utters being the answer to some
other word spoken or suggested by somebody else.

III. The tendency of the preceding remarks has been to show that
Psychology is necessarily a fragment, and is not and cannot be a
connected system. We cannot define or limit the mind, but we can
describe it. We can collect information about it; we can enumerate the
principal subjects which are included in the study of it. Thus we are
able to rehabilitate Psychology to some extent, not as a branch of
science, but as a collection of facts bearing on human life, as a
part of the history of philosophy, as an aspect of Metaphysic. It is a
fragment of a science only, which in all probability can never make any
great progress or attain to much clearness or exactness. It is however
a kind of knowledge which has a great interest for us and is always
present to us, and of which we carry about the materials in our own
bosoms. We can observe our minds and we can experiment upon them, and
the knowledge thus acquired is not easily forgotten, and is a help to us
in study as well as in conduct.

The principal subjects of Psychology may be summed up as follows:--

a. The relation of man to the world around him,--in what sense and
within what limits can he withdraw from its laws or assert himself
against them (Freedom and Necessity), and what is that which we suppose
to be thus independent and which we call ourselves? How does the inward
differ from the outward and what is the relation between them, and where
do we draw the line by which we separate mind from matter, the soul
from the body? Is the mind active or passive, or partly both? Are its
movements identical with those of the body, or only preconcerted and
coincident with them, or is one simply an aspect of the other?

b. What are we to think of time and space? Time seems to have a nearer
connexion with the mind, space with the body; yet time, as well as
space, is necessary to our idea of either. We see also that they have
an analogy with one another, and that in Mathematics they often
interpenetrate. Space or place has been said by Kant to be the form of
the outward, time of the inward sense. He regards them as parts or
forms of the mind. But th
