woman is to be regarded as biologically equal to man
depends on how one uses the word "equal." If it is meant that woman is
as well adapted to her own particular kind of work as is man to his, the
statement will readily be accepted. Unfortunately, feminists show a
tendency to go beyond this and to minimize differentiation in their
claims of equality. An attempt is made to show that women do not differ
materially from men in the nature of their capacity of mental or
physical achievement. Mrs. Charlotte Perkins Gilman makes the logical
application by demanding that little girls' hair be cut short and that
they be prevented from playing with dolls in order that differences
fostered in this way be reduced.

In forming a judgment on this proposition, it must be remembered that
civilization covers not more than 10,000 years out of man's history of
half a million or more. During 490,000 out of the 500,000 years, man was
the hunter and warrior; while woman stayed at home of necessity to bear
and rear the young, to skin the prey, to prepare the food and clothing.
He must have a small knowledge of biology who could suppose that this
long history would not lead to any differentiation of the two sexes;
and the biologist knows that man and woman in some respects differ in
every cell of their bodies: that, as Jacques Loeb says, "Man and woman
are, physiologically, different species."

But the biologist also knows that sex is a quantitative character. It is
impossible to draw a sharp line and say that those on one side are in
every respect men, and those on the other side in every respect women,
as one might draw a line between goats and sheep. Many women have a
considerable amount of "maleness"; numerous men have distinct feminine
characteristics, physical and mental. There is thus an ill-defined
"intermediate sex," as Edward Carpenter called it, whose size has been
kept down by sexual selection; or better stated there is so much
overlapping that it is a question of different averages with many
individuals of each sex beyond the average of the other sex.

A perusal of Havelock Ellis' book, _Man and Woman_, will leave little
doubt about the fact of sex differentiation, just as it will leave
little doubt that one sex is, in its way, quite as good as the other,
and that to talk of one sex as being inferior is absurd.

It is worth noting that the spread of feminism will reinforce the action
of sexual selection in keeping down the numb
