What gives life meaning is a form of rebellion, rebellion against reason, an insistence on believing passionately what we cannot believe rationally. The meaning of life is to be found in passion—romantic passion, religious passion, passion for work and for play, passionate commitments in the face of what reason knows to be meaningless.

[W]hat we also see in sex is a kind of submissiveness. But not a kind of submissiveness which is simply 'do what you like, I'm just here for you', but it...is, or can be, very manipulative. It is a way of getting the other person to exercise all his or her efforts towards pleasing you, and in that way controlling what they're thinking, and in particular what they're thinking of you.

We choose our friends on the basis of, among other things, our conception of ourselves. That's not to say that friendship is narcissistic, it doesn't follow that we choose people 'like ourselves'; in fact we might choose people very different than ourselves. For example, if I'm not very intelligent, and I'm concerned about my lack of intelligence, I might take up with an extremely intelligent woman, precisely in order to have her intelligence, in some sense, radiate onto me.The idea is that in friendship what we do is we pick people who are going to reinforce, in some sense, our own conception of ourselves. So if I think of myself as intelligent, or I want to think of myself as intelligent, whether or not I pick a partner who is also intelligent, what is going to be essential is that it's going to be a partner who somehow expands my notion of my own intelligence, either by telling me all the time, perhaps, how intelligent I am, or maybe by always contradicting me in such a way that I can prove my intelligence with her or him.

The thoroughly guilty man has an advantage over all of us; he cannot be found more guilty of anything, since he has already found himself guilty of everything. This may sound like an absurdity - causing oneself extreme pain in order not to feel any number of little pains of lesser guilts and shames, but it has its own logic. A man more easily adapts to what he inflicts upon himself; as to his own judgement, he is already committed to it and willing to live with it.
