"Know thyself," a saying by the renowned philosopher A. Nonymous, is inscribed on the temple of Apollo at Delphi. In Greek, it's "Gnothi SeAuton" - if you'll excuse my clumsy transliteration. Plato attributes the saying to the Seven Wise Men, one of whom was undoubtedly named A. Nonymous.
And that's about all I can remember from two years of Greek class. I hope that's enough to make Mom proud.

I was searching my feeble memory to recall the rest of the song Jon quoted above. Thank Greenhaus it's in the database - it's Life's Railway to Heaven.
