If I had not existed, someone else would have written me, Hemingway, Dostoyevsky, all of us. Proof of that is that there are about three candidates for the authorship of Shakespeare’s plays. But what is important is Hamlet and A Midsummer Night’s Dream, not who wrote them, but that somebody did.
The artist is of no importance. Only what he creates is important, since there is nothing new to be said. Shakespeare, Balzac, Homer have all written about the same things, and if they had lived one thousand or two thousand years longer, the publishers wouldn’t have needed anyone since.
