“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.”

“Moral certainty is always a sign of cultural inferiority. The more uncivilized the man, the surer he is that he knows precisely what is right and what is wrong. All human progress, even in morals, has been the work of men who have doubted the current moral values, not of men who have whooped them up and tried to enforce them. The truly civilized man is always skeptical and tolerant, in this field as in all others. His culture is based on "I am not too sure.”

“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.”

“The more uncivilized the man, the surer he is that he knows precisely what is right and what is wrong. All human progress, even in morals, has been the work of men who have doubted the current moral values, not of men who have whooped them up and tried to enforce them. The truly civilized man is always skeptical and tolerant, in this field as in all others. His culture is based on - I am not too sure.”

“The central belief of every moron is that he is the victim of a mysterious conspiracy against his common rights and true deserts.”

“I do not pretend, of course, that I have never done it; mere politeness forces one to it; there are women who sulk and grow bellicose unless one at least makes the motions of kissing them. But what I mean is that I have never found the act a tenth part as agreeable as poets, the authors of musical comedy librettos, and (on the contrary side) chaperones and the gendarmerie make it out. The physical sensation, far from being pleasant, is intensely uncomfortable—the suspension of respiration, indeed, quickly resolves itself into a feeling of suffocation—and the posture necessitated by the approximation of lips and lips is unfailingly a constrained and ungraceful one. Theoretically, a man kisses a woman perpendicularly, with their eyes, those "windows of the soul," synchronizing exactly. But actually, on account of the incompressibility of the nasal cartilages, he has to incline either his or her head to an angle of at least 60 degrees, and the result is that his right eye gazes insanely at the space between her eyebrows, while his left eye is fixed upon some vague spot behind her. An instantaneous photograph of such a maneuvre, taken at the moment of incidence, would probably turn the stomach of even the most romantic man, and force him, in sheer self-respect, to renounce kissing as he has renounced leap-frog and walking on stilts.”

“Nevertheless, it is even harder for the average ape to believe that he has descended from man.”
