“It is particularly incumbent on those who never change their opinion, to be secure of judging properly at first.”

“Those who judge others; first, need to know; how to judge self.”

“Don't concern yourself with the opinions of those who judge you. That is placing on them an importance they do not have.”

“Judgment is given to men that they may use it. Because it may be used erroneously, are men to be told that they ought not to use it at all? To prohibit what they think pernicious is not claiming exemption from error, but fulfilling the duty incumbent on them, although fallible, of acting on their conscientious conviction. If we were never to act on our opinions, because those opinions ‘lay be wrong, we should leave all our interests uncared for, and all our duties unperformed. An objection which applies to all conduct can be no valid objection to any conduct in particular.”

“To give a person an opinion one must first judge well whether that person is of the disposition to receive it or not.”

“Those who never retract their opinions love themselves more than they love truth.”
