Humour is human. Why? Well, because the Philosopher, Aristotle, says so.

Philosophy is the art of dying.Philosophy is an activity that has always been concerned with how one seizes hold of one's mortality, and I see myself continuing a very ancient tradition that goes back to Socrates and Epicurus, which is that to be a philosopher is to try and learn how to die. In learning how to die, one learns how to live.

Any philosophical and theoretical assurance that laughter is unique to the human being becomes somewhat unsure when one turns to the anthropological literature.

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.

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.

Being anthropologically respectful of all faiths means being committed to none, and being left to drift without an anchor for one's most deeply held beliefs. To have such an anchor means being committed to a specific community. The only way Obama can overcome his sense of detachment and resolve his mother's dilemma is through a commitment to Christianity.

It's complicated. On the one hand we're killer apes, and on the other hand we have this metaphysical longing.
