ssibly purely thyroid in its determination). With
the advent of the gonads upon the scene, judgments become the centre
of the play's plot undoubtedly. The intelligence of eunuchs and
eunuchoids is in general low. The skull and brain of castrates, animal
and human, is smaller than the average. Gall, the physiologist who
popularized ideas concerning the meaning of the protuberances and
depressions of the head in relation to faculty and character, early in
the nineteenth century, was the first to prove this. Among historic
castrates, eunuchs, not a single example of great intellect, of the
creative type, is known. On the contrary, the native gifts of the mind
were destroyed. Thus Abelard, who was punished with castration by his
uncle for his love affair with Heloeise, never composed a verse of
poetry thereafter.

IMAGINATION AS AN ENDOCRINE GIFT

That brings us to the consideration of imagination as influenced by
the endocrines. The physical conditions of exercise of the imaginative
faculty have not been sufficiently investigated. Alcohol has long been
known to act as an evocant of strange images. The hallucinations of
delirium tremens are the results obtained in extreme intoxication. A
strangely imaged flow of consciousness, the imaginative state, may
also be evoked by morphine and cannabis indica. There is no doubt
that the brain cells may be made to combine in the fresh, novel, and
unfamiliar associations that are recognized as unreal.

Francis Galton, pioneer student of the conditionings of human faculty,
left an interesting study of the visualising capacity, so far as it
could be attacked by the statistical method. Two of his conclusions
are worth repeating for our purposes. One is that the power to imagine
is poor in philosophers and men of science. The other that it is
higher in the female sex than in the male. We have seen that the
philosophic, scientific, intellectual mind, the capacity to abstract,
and think in terms of abstractions, is definitely dependent upon
proper secretion by the ante-pituitary. In woman, the post-pituitary
is generally predominant over the ante-pituitary. Though we are in
need of a series of studies of the endocrine traits and composition of
men endowed with high imaginative qualities, and so are at a loss, we
have indications of an endocrine control of the state of consciousness
we speak of as the imaginative.
