The German philosopher Walter Benjamin had the curious notion that we could change the past. For most of us, the past is fixed while the future is open.

The role of the intellectual, so it is said, is to speak truth to power. Noam Chomsky has dismissed this pious tag on two grounds. For one thing, power knows the truth already; it is just busy trying to conceal it. For another, it is not those in power who need the truth, but those they oppress.

God chose what is weakest in the world to shame the strong.

Virtue is something you have to get good at, like playing the trombone or tolerating bores at parties. Being a virtuous human being takes practice; and those who are brilliant at being human (what Christians call the saints) are the virtuosi of the moral sphere - the Pavarottis and Maradonas of virtue.

I say that virtue is really all about enjoying yourself, living fully; but of course it is far from obvious what living fully actually means.

The New Testament is a brutal destroyer of human illusions. If you follow Jesus and don't end up dead, it appears you have some explaining to do. The stark signifier of the human condition is one who spoke up for love and justice and was done to death for his pains. The traumatic truth of human history is a mutilated body.

Deconstruction insists not that truth is illusory but that it is institutional.
