There are only three quotes in this section, so I put them all in tonight.
“We must not contradict, but instruct him that contradicts us; for a madman is not cured by another running mad also.” – Antisthenes
“We take contradiction more easily than is supposed, if not violently given, even though it is well founded.-Hearts are like flowers; they remain open to the softly falling dew, but shut up in the violent downpour of rain.” – Richter
“Assertion is not an argument; to contradict the statement of an opponent is not proof that you are correct.” – Johnson
