If history, philosophy and so on vanish from academic life, what they leave in their wake may be a technical training facility or corporate research institute. But it will not be a university in the classical sense of the term, and it would be deceptive to call it one.

In the end, the humanities can only be defended by stressing how indispensable they are; and this means insisting on their vital role in the whole business of academic learning, rather than protesting that, like some poor relation, they don't cost much to be housed.

The study of history and philosophy, accompanied by some acquaintance with art and literature, should be for lawyers and engineers as well as for those who study in arts faculties.

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 irrational.

The most profound change that genetics brings about might not be scientific at all. It might be mental and even spiritual enrichment: a more expansive sense of who we humans are, existentially, and where we came from, and how we fit with other life on earth.

I would love to be remembered for ridding the world of disease, but my knowledge of science comes from episodes of 'Nova' and shows on the Discovery Channel. I don't think a superficial understanding of shark behavior and black holes can help cure diseases.

Science will explain how but not why. It talks about what is, not what ought to be. Science is descriptive, not prescriptive; it can tell us about causes but it cannot tell us about purposes. Indeed, science disavows purposes.

I've always loved science fiction. I think the smartest writers are science fiction writers dealing with major things.
