William Butler Yeats:

"I had three interests; interest in a form of literature, in a form of philosophy, and a belief in nationality. None of these seemed to have anything to do with the other, but gradually my love of literature and my belief in nationality came together. Then for years I said to myself that these two had nothing to do with my form of philosophy....Now all three are, I think, one, or rather all three are a discrete expression of a single conviction."
