A sidenote, but I like Bernard Williams' version of this idea even better than the original. It's the first sentence of his survey article "The Legacy of Greek Philosophy":

The legacy of Greece to Western Philosophy is Western Philosophy.

Isn't philosophy the mother of science?

Yes, but you still dicked up the quote. Footnotes and mothers are not synonymous, much to the relief of both.

For the anal-retentive among you. It would be footnotes and children are not synonymous. Not footnotes and mothers. Philosophy generates science. Western philosophy is a footnote. Your transitives are mixed up.

You can generalize and say "philosophy and science are derived from Greek works, which are still relevant" and help this guy out, or we can play word games. I could give a shit what the actual quote was. My goal wasn't to impress the guy with my knowledge of quotes, it was to offer a recommendation.

Sorry, I really didn't need to be so rude. That said, I think getting quotes right is important if you're going to use them. Otherwise you're contributing to sum total of misinformation in the world.
