dor or strong sexual
power--which, render him or her irresistible to a member of the
opposite sex.

But homeliness, ugliness or deformity have their limits, and I
challenge anybody to bring forth an authenticated case in which a man
fell in love with a woman--or vice versa--who had an enormous tumor on
one side of the face, which made her look like a monstrosity, or whose
nose was sunk in as a result of lupus or syphilis, or whose cheek was
eaten away by cancer. Love under such circumstances is an absolute
impossibility, because there is physical aversion here, and physical
aversion is fatal to the _genesis_ of love. A man who loved a woman
may continue to love her after she has become disfigured by disease,
but he cannot fall in love with such a woman.

I will repeat, then, and I trust you will agree with me on this point:
sexual attraction is the foundation of all love between the opposite
sexes. Where sexual attraction is lacking you can give the feeling any
other name you choose: it will not be love.

=Other Requisites.= But a foundation is not a whole structure. To
insure the stability of a high intricate building we must give it a
good solid foundation; but the foundation does not make the building.
That still remains to be built. So sexual attraction is the foundation
of all love, but it does _not_ constitute love. Many more factors,
many more wonderful stones are needed before the wonderful structure
called love is brought into existence. This wonderful structure
sometimes goes up in the twinkling of an eye, as if by the touch of a
magic wand--who has not seen or heard of instances of "love at first
sight!"--but the rapidity of the growth of the structure called Love
does not militate against our assertion that many stones, much
variegated material, and a strong cement are needed for its
completion. Fairies sometimes work very quickly.

A little thought will show clearly that Love is not merely sexual
love, not merely a desire to gratify the sexual instinct. If love were
merely sexual desire, then one member of the opposite sex, or at least
one attractive member, would be as good as any other. And indeed in
animals and in the lower races, where love as we understand it does
not exist, this is the case. To a male dog any female dog is as good
as another, and vice versa. Cats are not particular in the choice of
their mates, nor are cows, horses, etc. And the same is true of the
primitive savage races, and eve
