"If I have no vanity, I take no delight in praise; if I be void of ambition, power gives me no enjoyment; if I be not angry, the punishment of an adversary is totally indifferent to me." from "Of Self-Love: Appendix II" An Inquiry Concerning The Principles Of Morals
"Truth which are pernicious to society, if any such there be, will yield to errors which are salutary and advantageous."
