each upheaval it settles down as peacefully as the vine-growers on
Vesuvius, accepting the last lava crust as permanent ground.

What we see immediately around us, what we are born into and grow up
with, be it mental furniture or physical, we assume to be the order of
nature.

If a given idea has been held in the human mind for many generations, as
almost all our common ideas have, it takes sincere and continued effort
to remove it; and if it is one of the oldest we have in stock, one of
the big, common, unquestioned world ideas, vast is the labor of those
who seek to change it.

Nevertheless, if the matter is one of importance, if the previous idea
was a palpable error, of large and evil effect, and if the new one is
true and widely important, the effort is worth making.

The task here undertaken is of this sort. It seeks to show that what we
have all this time called "human nature" and deprecated, was in great
part only male nature, and good enough in its place; that what we have
called "masculine" and admired as such, was in large part human, and
should be applied to both sexes: that what we have called "feminine" and
condemned, was also largely human and applicable to both. Our
androcentric culture is so shown to have been, and still to be, a
masculine culture in excess, and therefore undesirable.

In the preliminary work of approaching these facts it will be well to
explain how it can be that so wide and serious an error should have been
made by practically all men. The reason is simply that they were men.
They were males, avid saw women as females--and not otherwise.
