Genuinely great humour recognises the world it's describing and yet we are also called into question by it. That's what great art should do. That's what great philosophy should do. The one thing about humour is that this is an everyday practice that does this.

Being anthropologically respectful of all faiths means being committed to none, and being left to drift without an anchor for one's most deeply held beliefs. To have such an anchor means being committed to a specific community. The only way Obama can overcome his sense of detachment and resolve his mother's dilemma is through a commitment to Christianity.

Philosophy is the art of dying.Philosophy is an activity that has always been concerned with how one seizes hold of one's mortality, and I see myself continuing a very ancient tradition that goes back to Socrates and Epicurus, which is that to be a philosopher is to try and learn how to die. In learning how to die, one learns how to live.

For me, philosophy is an activity of thought that is common to human beings. Human beings at their best.

I think that when people are at their best, when they are thinking, reflecting, cogitating, then they are doing philosophy. So I don't see philosophy as an academic enterprise.

The other side of my work is political disappointment - the realization that we are living in an unjust world. "Blood is being spilled in the merriest way, as if it was champagne," Dostoevsky says. That raises the problem of justice, what it might mean in an unjust world and whether there can be an ethics and a political practice that would be able to face and face down the injustice of the present. How might we begin to think about that?

Poetry is difficult, I mean interesting poetry, not confessional babble or emotive propaganda. Reading a new poet is discovering an entire world, what Stevens called a 'mundo' and it takes a lot of time to orientate oneself in such a world. What we have to learn to do then, as teachers and militants of a poetic insurgency, is to encourage people to learn to love the difficulty of poetry. I simply do not understand much of the poetry that I love.
