Don't keep rewriting and polishing something if it isn't setting the world on fire: start something new instead and consider the earlier story a learning experience.

I watched 'Who' with a mixture of affection and exasperation through the eighties, always ready to cheer on the Doctor but seldom feeling that the series was playing to its strengths. Some of the adventures, revisited on DVD, turn out to be better than I remembered - others just as infuriating.

I've always loved far future SF, so it was more or less a given that I would one day want to write in that form.

I don't know why, but American sci-fi writers seem to focus on the near-future, which has given us Brits a clear run at the most fascinating.

I think computer science, by and large, is still stuck in the Modern age.

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.

Do you not see what damage has been done to science through this: i.e. pedants wishing to be philosophers; to treat of natural things, and mix themselves with and decide about things Divine?

The science of politics is the one science that is deposited by the streams of history, like the grains of gold in the sand of a river; and the knowledge of the past, the record of truths revealed by experience, is eminently practical, as an instrument of action and a power that goes to making the future.
