“Those who can -- do. Those who can't -- teach.”

“There are two kinds of Europeans: The smart ones, and those who stayed behind.”

“The men the American people admire most extravagantly are the most daring liars; the men they detest most violently are those who try to tell them the truth.”

“The way to deal with superstition is not to be polite to it, but to tackle it with all arms, and so rout it, cripple it, and make it forever infamous and ridiculous. Is it, perchance, cherished by persons who should know better? Then their folly should be brought out into the light of day, and exhibited there in all its hideousness until they flee from it, hiding their heads in shame. True enough, even a superstitious man has certain inalienable rights. He has a right to harbor and indulge his imbecilities as long as he pleases, provided only he does not try to inflict them upon other men by force. He has a right to argue for them as eloquently as he can, in season and out of season. He has a right to teach them to his children. But certainly he has no right to be protected against the free criticism of those who do not hold them. He has no right to demand that they be treated as sacred. He has no right to preach them without challenge.”

“All government, in its essence, is a conspiracy against the superior man: its one permanent object is to oppress him and cripple him. If it be aristocratic in organization, then it seeks to protect the man who is superior only in law against the man who is superior in fact; if it be democratic, then it seeks to protect the man who is inferior in every way against both. One of its primary functions is to regiment men by force, to make them as much alike as possible and as dependent upon one another as possible, to search out and combat originality among them. All it can see in an original idea is potential change, and hence an invasion of its prerogatives. The most dangerous man to any government is the man who is able to think things out for himself, without regard to the prevailing superstitions and taboos. Almost inevitably he comes to the conclusion that the government he lives under is dishonest, insane and intolerable, and so, if he is romantic, he tries to change it. And even if he is not romantic personally he is very apt to spread discontent among those who are.”

“It is the dull man who is always sure, and the sure man who is always dull.”

“I am wholly devoid of public spirit or moral purpose. This is incomprehensible to many men, and they seek to remedy the defect by crediting me with purposes of their own. The only thing I respect is intellectual honesty, of which, of course, intellectual courage is a necessary part. A Socialist who goes to jail for his opinions seems to me a much finer man than the judge who sends him there, though I disagree with all the ideas of the Socialist and agree with some of those of the judge. But though he is fine, the Socialist is nevertheless foolish, for he suffers for what is untrue. If I knew what was true, I'd probably be willing to sweat and strive for it, and maybe even to die for it to the tune of bugle-blasts. But so far I have not found it.”
