“They dispute not in order to find or even to seek Truth, but for victory, and to appear the more learned and strenuous upholders of a contrary opinion. Such persons should be avoided by all who have not a good breastplate of patience.”
― Giordano Bruno

“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

“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

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