“To argue with a man who has renounced the use and authority of reason, and whose philosophy consists in holding humanity in contempt, is like administering medicine to the dead, or endeavoring to convert an atheist by scripture.”
― Thomas Paine, The American Crisis

“It does take great maturity to understand that the opinion we are arguing for is merely the hypothesis we favor, necessarily imperfect, probably transitory, which only very limited minds can declare to be a certainty or a truth.”
― Milan Kundera, Encounter
