1.   "There are women who have no inner life wherever one looks for it, being nothing but masks. That man is to be pitied who lets himself in with such ghostly, necessarily unsatisfying creatures; but just these women are able to stimulate man's desire most intensely: he searches for their souls - and searches on and on."
   

These are Nietzsche’s remarks. Despite his misogynistic tone I think there is something valid in what he says. I've known women like he describes and understand their attraction. I also understand the dangers they pose. If there is a solution it is simply to limit such liaisons to sex.

One of the startling qualities of sex is that is has the capacity for bridging huge gaps. It can cross a divide where there is no other connection, no shared sense of value, common cause or compatibility. In these unions the absence of sex would render them non-starters. Sex fills the space. But any attempt to bond with someone in such a situation, sex aside, is liable to failure.

I think there is the nub of Nietzsche's problem. You have to love and leave these types, and sooner rather than later. Few men are able to do this but it is only those few who will safely negotiate the perils of women in masks. When sex quenches the appetite you can lose interest in such a woman. This might bring about the soulful response apparently deficient in her. It is invariably the very fact that you no longer want her that stimulates her illusive inner self. A curious irony typical of the daftness of life. And to defuse the explicit sexism here: the phenomenon is perfectly reversible, man to woman or woman to man.

So I would say to Nietzsche in his moment of nemesis: "Forget the soul, man. Go for the sex!"
