“An argument in apologetics, when actually used in dialogue, is an extension of the arguer. The arguer's tone, sincerity, care, concern, listening, and respect matter as much as his or her logic - probably more. The world was won for Christ not by arguments but by sanctity: "What you are speaks so loud, I can hardly hear what you say.”
― Peter Kreeft, Pocket Handbook of Christian Apologetics

“Those who plead their cause in the absence of an opponent can invent to their heart's content, can pontificate without taking into account the opposite point of view and keep the best arguments for themselves, for aggressors are always quick to attack those who have no means of defence.”
― Christine de Pizan, Der Sendbrief vom Liebesgott / The Letter of the God of Love

“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

“There can be no progress without head-on confrontation.”
― Christopher Hitchens, Love, Poverty, and War: Journeys and Essays
