I'm starting from the assumption that the traditional ideal of university education is rarely suitable for women. Given this premise, what should a woman do who comes to tradition after receiving such an education? Should she try to hide it? Should she try to use it in God's service in some way? Is there something she ought to do to counteract its bad influence? What do you all think?
Eh, I think that the problem with secondary education is not the education itself, but rather the secular environment in which it's delivered today. All Catholics should, wherever possible, avoid the collegiate route or limit one's exposure to those classes which are absolutely necessary to get one's degree. One can ask around campus, find out which professors have a reputation for being overtly liberal or antagonistic to Christianity, and avoid taking classes. That said, if a woman is planning to fulfill the traditional role of her gender as homemaker, I don't feel that a higher education is strictly necessary, or even helpful. On the other hand though, there's absolutely nothing wrong with educating oneself in whatever discipline one finds interesting. The cultivation of one's God-given intellect is a wonderful thing.
If a woman has a secondary education (I do not count such things as business or post-Regency English literature degrees), she need not hide it. Many men, myself included, find an intelligent woman to be very attractive. The only caution I would have is that many educated women, especially in scientific circles, often suffer crippling insecurity. Even in this overly feminized society, the sciences are dominated by males and women often feel the need to debate to prove that they're just as intelligent or good at their profession as men. If such a woman comes to the traditional Catholic faith, she must learn to embrace the meekness that is exemplified by our Immaculate Queen and submit to her husband's judgement where it does not place her in danger of sin.
