CHAPTER II.
WHAT OUR MINDS HAVE IN COMMON--INTROSPECTIVE PSYCHOLOGY.
Of all the sources now indicated from which the psychologist may draw, that of so-called Introspective Psychology--the actual reports of what we find going on in our minds from time to time--is the most important.

This is true for two great reasons, which make Psychology different from all the other sciences.

The first claim which the introspective method has upon us arises from the fact that it is only by it that we can examine the mind directly, and get its events in their purity.

Each of us knows himself better than he knows any one else.

So this department, in which we deal each with his own consciousness at first hand, is more reliable, if free from error, than any of those spheres in which we examine other persons, so long as we are dealing with the psychology of the individual.
