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.

In relation to the question of hope, I think the only hope we have is hope against hope. We hope for a better world. But of course we can do better than just hope.

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.

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.

There is something desperately lonely about Barack Obama's universe. One gets the overwhelming sense of someone yearning for connection, for something that binds human beings together, for community and commonality, for what he repeatedly calls "the common good". This is hardly news.

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.

Melancholia for Freud is the relationship that the subject takes up with respect to itself from the position of what he calls conscience or what he later calls the super-ego. And that can be lacerated - if you think of the anorexic who sees themselves from the perspective of the image they have, of the image they have of themselves in the mirror which is false - that would be the super-ego. Super-ego is what generates depression and it is what has to be dealt with in psychoanalysis.
