When I was a college student I was always impressed how a discussion of Hegel, Kant, Hobbes, or Schopenhauer would get women to eagerly peel their panties off.

To be slightly more serious, I usually found DH Lawrence, Sylvia Plath, WB Yeats, or Erica Jong more effective.

John Stuart Mill would certainly say so...
And when you're not wading through all the tripe like anti-realism, it certainly is a very satisfying thing to study.

All of the great thinkers down through time were exploring the great questions of life and existance for the greater purpose of scoring with chicks, existentially of course.

At its best it is.

Philosophy was created by men who had nothing else better to do but sit around and speculate and most of there speculation was down right wrong because the reasoning behind it was error ridden. Philosophy blasshhhhhh

Don't underestimate the enlightening aftereffects of theological, ideological and scientific postulation. Though I wouldn't advise mixing the two, accidentally invalidating your own existence can really dampen one's libido.
