lack of the most elementary sense of biological continuity to assert that
in man so fundamental and involuntary a process can suddenly be
revolutionized. That the sexual impulse is very often associated with a
strong desire for offspring there can be no doubt, and in women the
longing for a child--that is to say, the longing to fulfill those
functions for which their bodies are constituted--may become so urgent and
imperative that we may regard it as scarcely less imperative than the
sexual impulse. But it is not the sexual impulse, though intimately
associated with it, and though it explains it. A reproductive instinct
might be found in parthenogenetic animals, but would be meaningless,
because useless, in organisms propagating by sexual union. A woman may not
want a lover, but may yet want a child. This merely means that her
maternal instincts have been aroused, while her sexual instincts are still
latent. A desire for reproduction, as soon as that desire becomes
instinctive, necessarily takes on the form of the sexual impulse, for
there is no other instinctive mechanism by which it can possibly express
itself. A "reproductive instinct," apart from the sexual instinct and
apart from the maternal instinct, cannot be admitted; it would be an
absurdity. Even in women in whom the maternal instincts are strong, it may
generally be observed that, although before a woman is in love, and also
during the later stages of her love, the conscious desire for a child may
be strong, during the time when sexual passion is at its highest the
thought of offspring, under normally happy conditions, tends to recede
into the background. Reproduction is the natural end and object of the
sexual instinct, but the statement that it is part of the contents of the
sexual impulse, or can in any way be used to define that impulse, must be
dismissed as altogether inacceptable. Indeed, although the term
"reproductive instinct" is frequently used, it is seldom used in a sense
that we need take seriously; it is vaguely employed as a euphemism by
those who wish to veil the facts of the sexual life; it is more precisely
