tion and treatment of the materials of experience.

There is another term very current in psychology by which this same
process is sometimes indicated: the phrase Association of Ideas. This
designates the fact that when two things have been perceived or
thought of together, they tend to come up together in the mind in the
future; and when a thing has been perceived which resembles another,
or is contrasted with it, they tend to recall each other in the same
way. It is plain, however, that this phrase is applied to the single
thoughts, sensations, or other mental materials, in their relations or
connections among themselves. They are said to be "associated" with
one another. This way of speaking of the mental materials, instead of
speaking of the mind's activity, is convenient; and it is quite right
to do so, since it is no contradiction to say that the thoughts, etc.,
which the mind "apperceives" remain "associated" together. From this
explanation it is evident that the Association of Ideas also comes
under the mental process of Apperception of which we have been
speaking.

There is, however, another tendency of the mind in the treatment of
its material, a tendency which shows us in actual operation the
activity with which we have now become familiar. When we come to look
at any particular case of apperception or association we find that the
process must go on from the platform which the mind's attainments have
already reached. The passing of the mental states has been likened to
a stream which flows on from moment to moment with no breaks. It is so
continuous that we can never say: "I will start afresh, forget the
past, and be uninfluenced by my history." However we may wish this, we
can never do it; for the oncoming current of the stream is just what
we speak of as ourselves, and we can not avoid bringing the memories,
imaginations, expectations, disappointments, etc., up to the present.
So the effect which any new event or experience, happening for the
first time, is to have upon us depends upon the way it fits into the
current of these onflowing influences. The man I see for the first
time may be so neutral to me that I pass him unregarded. But let him
return after I have once remarked him, or let him resemble a man whom
I know, or let him give me some reason to observe, fear, revere, think
of him in any way, then he is a positive factor in my stream. He has
been taken up into the flow of my mental life, and he hen
