How might a modern defender of womens rights respond to Defoe's "An Academy for Women?"

A modern defender of women's rights would be offended by
this essay.  Such a person would condemn it for having a condescending and sexist
attitude towards women.

In modern times, most people (and
certainly those who would be called "defenders of women's rights") believe that women
have essentially the same sorts of mental abilities that men do.  Defoe clearly does not
believe this.  Defoe's vision for women's education is one in which women are educated
for the purpose of making them better companions and wives.  In other words, he wants
women to be better suited to please men.  A modern view of women's education holds that
the point of education is to allow women to pursue whatever sort of career they want. 
It is meant to enrich the lives of the women themselves, not to make them better
wives.

For this reason, a modern defender of women's rights
(at least in the Western world) would be appalled by Defoe's
attitudes.
