ffected her imagination, and recorded the answers; and absolutely not
one case came right, though, when the child was anything remarkable,
they afterwards made the cap to fit."
Any doctor who has handled many maternity cases can call to mind
instances where every condition was present to perfection, for the
production of maternal impression, on the time-honored lines. None
occurred. Most mothers can, if they give the matter careful
consideration, duplicate this experience from their own. Why is it that
results are so rare?
That Darwin gave the true explanation of a great many of the alleged
cases is perfectly clear to us. When the child is born with any peculiar
characteristic, the mother hunts for some experience in the preceding
months that might explain it. If she succeeds in finding any experience
of her own at all resembling in its effects the effect which the infant
shows, she considers she has proved causation, has established a good
case of prenatal influence.
It is not causation; it is coincidence.
If the prospective mother plays or sings a great deal, with the idea of
giving her child a musical endowment, and the child actually turns out
to have musical talent, the mother at once recalls her yearning that
such might be the case; her assiduous practice which she hoped would be
of benefit to her child. She immediately decides that it did benefit
him, and she becomes a convinced witness to the belief in prenatal
culture. Has she not herself demonstrated it?
She has not. But if she would examine the child's heredity, she would
probably find a taste for music running in the germ-plasm. Her study and
practice had not the slightest effect on this hereditary disposition; it
is equally certain that the child would have been born with a taste for
music if its mother had devoted eight hours a day for nine months to
cultivating thoughts of hatred for the musical profession and repugnance
for everything that possesses rhythm or harmony.
It necessarily follows, then, that attempts to influence the inherent
nature of the child, physically or mentally, through "prenatal culture,"
are doomed to disappointment. The child develops along the lines of the
potentialities which existed in the two germ-cells that united to become
its origin. The course of its development can not be changed in any
specific way by any corresponding act or attitude of its mother, good
hygiene alone need be her concern.
It must necessarily
