I have often said that just as the French revolution, for instance, understood itself through antiquity, I think our time can be understood through the French revolution. It is quite a natural process to use other times to understand your own time.
Even if I couldn't get my early novels published, I could still write. I went into newspapers, where I got paid to write every day. If there's a better school for would-be novelists, I don't know what it is.
