ld a sensorial madness
(illusions, hallucinations); but by reason of its feeble intellectual
development the delirium causes a disorder of movements rather than of
images; its insane imagination is above all a motor insanity.

To hold that the creative imagination belonging to animals consists of
new combinations of movements is certainly an hypothesis. Nevertheless,
I do not believe that it is merely a mental form without foundation, if
we take into account the foregoing facts. I consider it rather as a
point in favor of the motor theory of invention. It is a singular
instance in which the original form of creation is shown bare. If we
wanted to discover it, it would be necessary to seek it where it is
reduced to the greatest simplicity--in the animal world.

CHAPTER II

THE CREATIVE IMAGINATION IN THE CHILD

At what age, in what form, under what conditions does the creative
imagination make its appearance? It is impossible to answer this
question, which, moreover, has no justification. For the creative
imagination develops little by little out of pure reproduction by an
evolutionary process, not by sudden eruption. Nevertheless, its
evolution is very slow on account of causes both organic and
psychological.

We could not dwell long on the organic causes without falling into
tiresome repetitions. The new-born infant is a spinal being, with an
unformed diffluent brain, composed largely of water. Reflex life itself
is not complete in him, and the cortico-motor system only hinted at; the
sensory centers are undifferentiated, the associational systems remain
isolated for a long time after birth. We have given above Flechsig's
observation on this point.

The psychological causes reduce thems
