Context

“How is it that they fail to perceive that when they try to strengthen their authority they are really destroying it; that to gain a hearing one must put oneself in the place of our hearers, and that to speak to the human heart, one must be a man. All these perfect people neither touch nor persuade; people always say, "It is easy for them to fight against passions they do not feel." Show your pupil your own weaknesses if you want to cure his; let him see in you struggles like his own; let him learn by your example to master himself and let him not say like other young men, "These old people, who are vexed because they are no longer young, want to treat all young people as if they were old;” source
