A broadsheet obituarist once pointed out to me that veteran soldiers die by rank. First to go are the generals, admirals and air marshals, then the brigadiers, then a bit of a gap and the colonels and wing commanders and passed-over majors, then a steady trickle of captains and lieutenants. As they get older and rarer, so the soldiers are mythologised and grow ever more heroic, until finally drummer boys and under-age privates are venerated and laurelled with honours like ancient field marshals. There is something touching about that.

Get up now and go and find Robert Kilroy-Silk. Smile in a warm, friendly sort of way, then punch him on the nose. Now go and find Robert on television, despite my best endeavours, this is still relatively easy to do. Wait for a close-up, same smile, and punch him on the nose. If you followed the instructions carefully, you will have noticed a distinct difference. On the one hand, you were suffused with a sense of public-spirited righteousness; on the other, you're probably dribbling blood. That's the difference between reality in life and reality on television.

Once upon a time, a historian told me that the most important choice a new historian could make was of his or her specialist subject. Most of the good stuff was far too overcrowded, so you had to pick about in the exotic and extinct. His recommendations were the Picts or the Minoans, because hardly anything was known about them and you could spend a happy lifetime of speculation.

The interesting adults are always the school failures, the weird ones, the losers, the malcontents, this isn’t wishful thinking. It’s the rule.

Television gives us the gift to see ourselves as we'd like to be seen.

Sport is how poor kids from poor countries pass through the eye of the needle to riches and recognition.

Television is a constant stream of fact, opinions, lies, moral dilemmas, plots: an infinitely complex and sophisticated torrent of information. How could it not make you cleverer? The only people who ever thought television rotted the brain and made kids dumb were those with a vested interest in other ways of learning, or those who were intellectually insecure, usually about books.
