@Olivier5,
Oh, and there's more to my change of mind than I wish to add, for brevity's sake. I will, however, list the philosophers that have impacted me along the way:
Robert Nozick
Ayn Rand (yes, I consider her a philosopher)
Quentin Meillassoux
Martin Heidegger (through all of his empty profoundness, there are a few gems in his philosophical thought)
Arthur Schopenhauer
Jean-Paul Sartre
Ludwig Witttgenstein (However pernicious his philosophy may be, he does make you think)
Richard Rorty (same as Wittgenstein)
Saul Kripke (total badass)
Alvin Plantinga
Quentin Smith (the dude who got me into modal logic. He's a platonist, but not too bad in my book)
Merleau-Ponty (eh, he's okay)
Edmund Husserl (another badass)
G.W.F. Hegel (a charlatan to the nth degree, but still worth reading)
Friedrich Nietzsche (love his prose and parts of his philosophy, provided that you can get past the "mask" he puts up)
Aristotle and Plato (gotta give credit to the giants of philosophy, Aristotle in particular)
There are others whose names I can't think of, but they're included too (at least in spirit).
