Philosophy, or involuntary confession?

In Beyond Good and Evil, Nietzsche opens by accusing philosophy thus far of mistaking prejudice for truth - accusing philosophers of dressing up their innate prejudices, drives and desires as that most pure and selfless quest - the quest for eternal, universal truth. Nietzsche, reasonably, attributes this dogmatism to Plato (and, as Whitehead said, all of Western philosophy is but footnotes to Plato), whose tales of Socrates and his dialectic undressing of his interlocutors (the intellectual equivalent of tying together the shoelaces of your enemy before they start running after you) has given philosophers ever since much comfort and joy.
