There is no way in which we can retrospectively erase the Treaty of Vienna or the Great Irish Famine. It is a peculiar feature of human actions that, once performed, they can never be recuperated. What is true of the past will always be true of it.

In the end, it is because the media are driven by the power and wealth of private individuals that they turn private lives into public spectacles. If every private life is now potentially public property, it is because private property has undermined public responsibility.

Because subjects like literature and art history have no obvious material pay-off, they tend to attract those who look askance at capitalist notions of utility. The idea of doing something purely for the delight of it has always rattled the grey-bearded guardians of the state. Sheer pointlessness has always been a deeply subversive affair.

We face a conflict between civilisation and culture, which used to be on the same side. Civilisation means rational reflection, material wellbeing, individual autonomy and ironic self-doubt; culture means a form of life that is customary, collective, passionate, spontaneous, unreflective and arational.

Imagine someone holding forth on biology whose only knowledge of the subject is 'The Book of British Birds,' and you have a rough idea of what it feels like to read Richard Dawkins on theology.

I enjoy popularisation and I think I'm reasonably good at it. I also think it's a duty. It's just so pedagogically stupid to forget how difficult one found these ideas oneself to begin with.

Evil may be 'unscientific' but so is a song or a smile.
