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.

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.

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.

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.

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 yearning for the common good comes from the refusal to accept that perhaps Americans have very little in common apart from the elements of a sometimes successful civil religion based around a sentimental, indeed sometimes teary-eyed, attachment to the constitution and a belief in the quasi-divine wisdom of the founding fathers.
