A woman may very well form a friendship with a man, but for this to endure, it must be assisted by a little physical antipathy.
Admiration for a quality or an art can be so strong that it deters us from striving to possess it.
Although I'm specifically looking for Nietzsche's statements about scientific method, I was interested in his prioritizing of science as the brawn for the philosopher's brain in the attribution of a hierarchy of values (quote not included here).
The quotes posted here show a serendipitous call and response regarding gender relations, I think. So, rather than having better spectacles (as quoted as his cure for love) to induce the necessary physical antipathy, it would seem that to appreciate a woman's friendship, it is only necessary to have BETTER BLOODY RESPECT & ADMIRATION!
