We live in a world that is dominated by science. And that's not a bad thing - not at all. But one of the problems with the scientific worldview is that it leads human beings to have an overwhelmingly theoretical relationship to the world. For example, I no longer accept my being in the world practically and then try to describe that or elucidate that; rather, I see the world theoretically as colors and objects and representations which are fed through my retina into the brain.

Obama dreams of a society without power relations, without the agonism that constitutes political life. Against such a position one might assert that justice is always an agon, a conflict, and to refuse this assertion is to consign human beings to wallow in some emotional, fusional balm.

Now, if laughter is proper to the human being, then the human being who does not laugh invites the charge of inhumanity, or at least makes us somewhat suspicious.

Philosophy teaches us to look at the world again. It brings out at a theoretical level what all plain, common, ordinary people, in a sense, know already.

There are lots of stories about how philosophy begins. Some people claim it begins in wonder; some people claim it begins in worry. I claim it begins in disappointment.

I've always been very keen on Pascal, and what I'm most keen on in Pascal is his emphasis upon human wretchedness. He has a phrase which goes something like 'Anxiety, boredom and inconstancy, that is the human condition' and I've always been very partial to that.

The culture of irony is the culture of postmodernism, which I would furiously want to denounce. We have to act ethically and politically. Irony is a defensive position, against reality. It always knows what to think about reality. The idea of commitment and engagement is central to me, which is not ironic.
