“Pleasure's fun. It's great, but you can't keep it going forever; just accept the fact that it's here and it's gone, and maybe then again, it will come back, and you'll get to do it again. Joy lasts forever. Pleasure is purely self-centered. It's all about your pleasure: it's about you. It's a selfish, self-centered emotion, that is created by a self-centered motive of greed. Joy is compassion. Joy is giving yourself to somebody else, or something else. And it's a kind of thing that is, in its subtlety and lowness, much more powerful than pleasure. You get hung up on pleasure; you're doomed. If you pursue joy; you will find everlasting happiness.”

Outline of a Morality Without Obligation or Sanction https://www.marxists.org/archive/guyau/1885/morality.htm (1885).
Context: A third equivalent of duty is borrowed from sensibility and not, like the preceding, from intelligence and activity. It’s the growing fusion of sensibilities, and the ever increasing sociable character of elevated pleasures, from which results a kind of duty or superior necessity which pushes us naturally and rationally towards others. By virtue of evolution, our pleasures grow and become increasingly impersonal; we cannot experience enjoyment within our selves as if on a deserted isle. Our milieu, to which we better adapt ourselves every day, is human society, and we can no more be happy outside of this milieu than we can breathe outside the air. The purely selfish happiness of certain Epicureans is a chimera, an abstraction, an impossibility; the true human pleasures are all more or less social. Pure egoism, rather than being an affirmation of the self, is a mutilation of the self.

Context: The point is not merely that human relationships are fulfilling; the Confucian claim runs deeper than that. It is rather that apart from human relationships there is no self. The self is a center of relationships. It is constructed through its interactions with others and is defined by the sum of its social roles.
