Sorry on the delay. I guess I'm using 'apology' equivocally. I recently taught on Plato's Apology, here are some gems from there:
"human wisdom is worth little or nothing."
"to fear death, gentlemen, is no other than to think oneself wise when one is not."
"wealth does not bring about excellence, but excellence makes wealth and everything else good for men, both individually and collectively."
"death is something I couldn't care less about, but that my whole concern is not to do anything unjust or impious."
"the unexamined life is not worth living for men."
"it is not difficult to avoid death, gentlemen; it is much more difficult to avoid wickedness, for it runs faster than death."
