Famous quotes containing the word axiom:
“You are bothered, I suppose, by the idea that you cant possibly believe in miracles and mysteries, and therefore cant make a good wife for Hazard. You might just as well make yourself unhappy by doubting whether you would make a good wife to me because you cant believe the first axiom in Euclid. There is no science which does not begin by requiring you to believe the incredible.”
—Henry Brooks Adams (18381918)
