There are two forms of disappointment that interest me: religious and political disappointment. Religious disappointment flows from the realization that religious belief is not an option for us. Political disappointment flows from the fact that there is injustice - that we live in a world that is radically unjust and violent, where might seems to equal right, where the poor are exploited by the rich, etc.

Just to say "Well, God is dead" in one breath is to say, in another, that nothing means anything. This is the moment of nihilism. Nihilism is the affirmation of meaninglessness.

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.

When the animal becomes human, the effect is pleasingly benign and we laugh outloud, "Okay come clean now. This isn't really about hunting, is it?" But when the human becomes animal, the effect is disgusting, and if we laugh at all, then it is what Beckett calls the "mirthless laugh", which laughs at that which is unhappy.

There's a floating distraction in the contemporary world, life at a distance enabled by technology. I want people to commit at the level of their subjectivity. The idea of subjective commitment is at the core of ethics, something that divides the self from itself. I become an ethical self. I cannot meet that ideal, I cannot fulfill it, it divides me from myself and it makes me strive harder. This ideal subjective ethical drive is at the heart of an absolutely earnest, radical politics that insists that people will be able to engage with each other, and they're lifted from irony at that point.

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.

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.
