CHAPTER XXVII

IMAGINATION

=Nature of.=--In our study of the various modes of acquiring individual
notions, attention was called to the fact that knowledge of a particular
object may be gained through a process of imagination. Like memory,
imagination is a process of re-presentation, though differing from it in
certain important regards.

1. Although imagination depends on past experiences for its images,
these images are used to build up ideal representations of objects
without any reference to past time.

2. In imagination the associated elements of past experience may be
completely dissociated. Thus a bird may be imagined without wings, or a
stone column without weight.

3. The dissociated elements may be re-combined in various ways to
represent objects never actually experienced, as a man with wings, or a
horse with a man's head.

Imagination is thus an apperceptive process by which we construct a
mental representation of an object without any necessary reference to
its actual existence in time.

=Product of Imagination, Particular.=--It is to be noted that in a
process of imagination the mind always constructs in idea a
representation of a _particular_ object or individual. For instance, the
ideal picture of the house I imagine situated on the hill before me is
that of a particular house, possessing definite qualities as to height,
size, colour, etc. In like manner, the future visit to Toronto, as it
is being run over ideally, is constructed of particular persons, places,
and events. So also when reading such a stanza as:

The milk-white blossoms of the thorn
Are waving o'er the pool,
Moved by the wind that breathes along,
So sweetly and so cool;

if the mind is able to combine into a definite outline of a particular
situation the various elements depicted, then the mental process of the
reader is one of imagination. It is not true, of course, that the
particular elements which enter into such an ideal representation are
always equally vivid. Yet one test of a person's power of imagination is
the definiteness with which the mind makes an ideal representation stand
out in consciousness as a distinct individual.
