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

Philosophy, for me, is a way of relearning to look at the world, a world that is familiar to us, that we know, that is shared by all human beings and also by nonhuman beings.

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.

I think governments are quietly terrified. There's massive unemployment, a recession they don't know how to deal with, and the measures they've taken are not working yet, and maybe they're not going to work. There's a prospect of significant social disorder.

I am opposing it with an idea of the history of philosophy as a history of philosophers, that is, a history of mortal, fragile and limited creatures like you and I. I am against the idea of clean, clearly distinct epochs in the history of philosophy or indeed in anything else. I think that history is always messy, contingent, plural and material. I am against the constant revenge of idealism in how we think about history.

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.

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.
