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.

The influence of being in New York, made me realize a lot of the ethical and political ideas I want to push or promote are best articulated within an anarchist program.

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.

We live in a world that is dominated by science. And that's not a bad thing - not at all. But one of the problems with the scientific worldview is that it leads human beings to have an overwhelmingly theoretical relationship to the world. For example, I no longer accept my being in the world practically and then try to describe that or elucidate that; rather, I see the world theoretically as colors and objects and representations which are fed through my retina into the brain.

Shore up the mean with reverence and terror. But never banish terror from the gates of the state. The stronger the fear, the stronger the reverence for the just, the stronger your country's wall and the city's safety.

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 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.
