He who cannot put his thoughts on ice should not enter into the heat of dispute.
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.
When two wise men are blaming one another, then time has come for you to be the third one.
No sensible man ever engages, unprepared, in a fencing match of words with a woman.
Any woman who is sure of her own wits, is a match, at any time, for a man who is not sure of his own temper.
