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.

The only answer to the question of the meaning of life has to begin from the fact of our human finitude, of our vulnerability and our fallibility.

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.

The thing about humour is that the super-ego is also at play, so what interested me, particularly in the last chapter which is key to the book -and no one seems to have picked this up in writings on Freud - is that, in the later Freud, the essence of humour is the ability to look at myself and find myself ridiculous. That makes me laugh.

If I had a religious experience, what I know for sure is that I would stop doing philosophy and would start doing religion, teaching classes in religion, preaching in a local church. That is fine and noble activity. But I do not feel entitled to engage in it. So for me philosophy is my fate.

The current situation with regard to theory is odd and maybe defined by a paradox.

For me philosophy begins with these experiences of disappointment: a disappointment at the level of what I would think of as "meaning," namely that, given that there is no God, what is the meaning of life? And, given that we live in an unjust world, how are we to bring about justice?
