“Certain forms of sex which do not lead to children are at present punished by the criminal law: this is purely superstitious, since the matter is one which affects no one except the parties directly concerned… The peculiar importance attached, at present, to adultery is quite irrational… Moral rules ought not to be such as to make instinctive happiness impossible.”

“There are certain irregularities which are not the subject of criminal law. But when the criminal law happens to be auxiliary to the law of morality, I do not feel any inclination to explain it away.”

“[The church] is in its major part an opponent still of progress and improvement in all the ways that diminish suffering in the world, because it has chosen to label as morality a certain narrow set of rules of conduct which have nothing to do with human happiness; and when you say that this or that ought to be done because it would make for human happiness, they think that has nothing to do with the matter at all. "What has human happiness to do with morals? The object of morals is not to make people happy."”

“The moral elements are among the most important in war. They constitute the spirit that permeates war as a whole, and at an early stage they establish a close affinity with the will that moves and leads a whole mass of force, practically merging with it, since the will is itself a moral quantity. Unfortunately they will not yield to academic wisdom. They cannot be classified or counted. They have to be seen or felt. … It is paltry philosophy if in the old-fashioned way one lays down rules and principles in total disregard of moral values. As soon as these appear one regards them as exceptions, which gives them a certain scientific status, and thus makes them into rules. Or again one may appeal to genius, which is above all rules; which amounts to admitting that rules are not only made for idiots, but are idiotic in themselves.”

“The whole evil of commercial prostitution arises out of the domination of Man in matters of sex. Better indeed were a Saturnalia of free men and women than the spectacle which as it is our great cities present at night. Here in sex, the women's instincts are, as a rule, so clean, so direct, so well-rooted in the needs of the race, that except for man's domination they would scarcely have suffered this perversion.”

“What will be the influence of communist society on the family? It will transform the relations between the sexes into a purely private matter which concerns only the persons involved and into which society has no occasion to intervene. It can do this since it does away with private property and educates children on a communal basis, and in this way removes the two bases of traditional marriage – the dependence rooted in private property, of the women on the man, and of the children on the parents.”

“History has stopped. Nothing exists except an endless present in which the Party is always right.”

“Logical analysis applied to mental phenomenon shows that there is but one law of mind, namely that ideas tend to spread continuously and to affect certain others which stand to them in a peculiar relation of affectibility. In this spreading they lose intensity, and especially the power of affecting others, but gain generality and become welded with other ideas.”

“No matter how happy I had been in the past I do not long for it. The present is always the moment for which I love.”

“In a State or Assemblage of People that live together in a Community, where there are Laws, Liberty can only consist in doing that which every One ought to do, and not to be constrained to do that which One ought not to do.”
