“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

“The most important tactic in an argument next to being right is to leave an escape hatch for your opponent so that he can gracefully swing over to your side without an embarrassing loss of face.”
― Stephen Jay Gould

“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
