But there is no doubt that to attempt a novel of ideas is to give oneself a handicap: the parochialism of our culture is intense. For instance, decade after decade bright young men and women emerge from their universities able to say proudly: 'Of course I know nothing about German literature.' It is the mode. The Victorians knew everything about German literature, but were able with a clear conscience not to know much about the French.

The youth do not see the old. They are not programmed to see the old, who are cancelled, negated, wiped out.

When you're young you think that you're going to sail into a lovely lake of quietude and peace. This is profoundly untrue.

Does political correctness have a good side? Yes, it does, for it makes us re-examine attitudes, and that is always useful. The trouble is that, with all popular movements, the lunatic fringe so quickly ceases to be a fringe; the tail begins to wag the dog. For every woman or man who is quietly and sensibly using the idea to examine our assumptions, there are twenty rabble-rousers whose real motive is desire for power over others. The fact that they see themselves as antiracists or feminists or whatever does not make them any less rabble-rousers.

What of course I would like to be writing is the story of the Red and White Dwarves and their Remembering Mirror, their space rocket (powered by anti-gravity), their attendant entities Hadron, Gluon, Pion, Lepton, and Muon, and the Charmed Quarks and the Coloured Quarks. But we can't all be physicists.

I do not think writers or anybody would sit down and think they must write about some cause, or theme, or something. If they write about their own experiences, something true is going to emerge.

I find myself increasingly shocked at the unthinking and automatic rubbishing of men which is now so part of our culture that it is hardly even noticed.
