“Pleasure limits the scope of human possiblity-the pleasure principle is a principle of homeostasis. Desire, on the other hand, finds its boundary, its strict relation, its limit, and it is in the relation to this limit that it is sustained as such, crossing the threshold imposed by the pleasure principle.”

“Stirner … holds to a joy-principle rather than to a pleasure-principle.”

“All law relations are determined by this principle: each one must restrict his freedom by the possibility of the freedom of the other. … My freedom is limited by the freedom of the other only on condition that he limits his freedom by the conception of mine. Otherwise he is lawless. Hence, if a law-relation is to result from my cognition of the other, the cognition and the consequent limitation of freedom must have been mutual. All law-relation between persons is, therefore, conditioned by their mutual cognition of each other, and is, at the same time, completely determined thereby.”

“As we grow older and realize more clearly the limitations of human happiness, we come to see that the only real and abiding pleasure in life is to give pleasure to other people.”

“If two bodies merely join together, that is not sex, it is merely pleasure. Sex goes far beyond pleasure. In sex, relaxation and tension go hand in hand, as do pain and pleasure, shyness and the courage to go beyond one’s limits.”

“There are limits on liberty, as there are limits on authority. The broad principle of those limits is generally recognized and accepted; no liberties may be exercised so as to injure others or injure the community.”

“Philosophy is an everlasting fire, sometimes damped down by setting itself limits, then flaring into new life as it consumes them. Every field of inquiry is limited, but philosophy has an essential relation to the question of limits, to its own limits.”

“The range of socially permissible and desirable satisfaction is greatly enlarged, but through this satisfaction, the Pleasure Principle is reduced—deprived of the claims which are irreconcilable with the established society. Pleasure, thus adjusted, generates submission.”

“Pain itself is merely a consequence of the desire for pleasure, the desire t destroy, to annihilate; in its supreme form, pain is a variety of pleasure.”

“Frugality is founded on the principle that all riches have limits.”
