“We naturally like what we have been accustomed to, and are attracted towards it. [...] The same is the case with those opinions of man to which he has been accustomed from his youth; he likes them, defends them, and shuns the opposite views.”

“From early youth we are accustomed to hearing falsified reports, and our minds have been saturated with prejudice for centuries, to the extent that we guard the fantastic lies like a treasure – so that in the end the truth becomes unbelievable and the lie appears to be true.”

“[F]or grief is felt not so much for the want of what we have never known, as for the loss of that to which we have been long accustomed.”

“He who knows only his own side of the case knows little of that. His reasons may be good, and no one may have been able to refute them. But if he is equally unable to refute the reasons on the opposite side, if he does not so much as know what they are, he has no ground for preferring either opinion... Nor is it enough that he should hear the opinions of adversaries from his own teachers, presented as they state them, and accompanied by what they offer as refutations. He must be able to hear them from persons who actually believe them...he must know them in their most plausible and persuasive form.”

“What virtue is there in a man who demonstrates goodness because he has been bred to it? It is his habit from youth. But a man who has known unkindness and want, for him to be kind and charitable to those who have been the cause of his misfortunes, that is a virtuous man.”

“If we assume man has been corrupted by an artificial civilization, what is the natural state? the state of nature from which he has been removed? imagine, wandering up and down the forest without industry, without speech, and without home.”
