Philosophical quotes-Preposterous fancy

Greek philosophy seems to begin with a preposterous fancy, with the proposition (of Thales) that water is the origin and mother-womb of all things. Is it really necessary to stop there and become serious? Yes, and for three reasons: firstly, because the proposition does enunciate something about the origin of things; secondly, because it does so without figure and fable; thirdly and lastly, because it contained, although only in the chrysalis state, the idea :everything is one. ..That which drove him (Thales) to this generalization was a metaphysical dogma, which had its origin in a mystic intuition and which together with the ever renewed endeavors to express it better, we find in all philosophies- the proposition: everything is one!
-Friedrich Nietzsche, The Greeks 1890
