“That man is best who sees the truth himself. Good too is he who listens to wise counsel. But who is neither wise himself nor willing to ponder wisdom is not worth a straw.”
“Civilisation is the distance that man has placed between himself and his own excreta.”
“Q: When is the perfect time? A: Who can say, but probably somewhere between haste and delay - and it's usually most wise to start today.”
“No man is wise enough by himself.”
