r of Imagination.

It is on this power that our attention should first be arrested; the
more so because it is usually spoken of in vague rhapsodical language,
with intimations of its being something peculiarly mysterious. There
are few words more abused. The artist is called a creator, which in one
sense he is; and his creations are said to be produced by processes
wholly unallied to the creations of Philosophy, which they are not.
Hence it is a paradox to speak of the "Principia," as a creation
demanding severe and continuous exercise of the imagination; but it is
only a paradox to those who have never analysed the processes of
artistic and philosophic creation.

I am far from desiring to innovate in language, or to raise
interminable discussions respecting the terms in general use.
Nevertheless we have here to deal with questions that lie deeper than
mere names. We have to examine processes, and trace, if possible, the
methods of intellectual activity pursued in all branches of Literature;
and we must not suffer our course to be obstructed by any confusion in
terms that can be cleared up. We may respect the demarcations
established by usage, but we must ascertain, if possible, the
fundamental affinities. There is, for instance, a broad distinction
between Science and Art, which, so far from requiring to be effaced,
requires to be emphasised: it is that in Science the paramount appeal
is to the Intellect---its purpose being instruction; in Art, the
paramount appeal is to the Emotions--its purpose being pleasure. A work
of Art must of course indirectly appeal to the Intellect, and a work of
Science will also indirectly appeal to the Feelings; nevertheless a
poem on the stars and a treatise on astronomy have distinct aims and
distinct methods. But having recognised the broadly-marked differences,
we are called upon to ascertain the underlying resemblances. Logic and
Imagination belong equally to both. It is only because men have been
attracted by the differences that they have overlooked the not less
important affinities. Imagination is an intellectual process common to
Philosophy and Art; but in each it is allied with different processes,
and directed to different ends; and hence, although the "Principia"
demanded an imagination of not less vivid and sustained power than was
demanded by "Othello," it would be very false psychology to infer that
the mind of Newton was competent to the creation of "Othello," or the
mind
