I had still the ambition, formed in Sligo in my teens, of living in imitation of Thoreau on Innisfree, a little island in Lough Gill, and when walking through Fleet Street very homesick I heard a little tinkle of water and saw a fountain in a shop window which balanced a little ball upon its jet, and began to remember lake water. From the sudden remembrance came my poem Innisfree.
I cannot accept the doctrine that in poetry there is a "suspension of belief." A poet must never make a statement simply because it is sounds poetically exciting; he must also believe it to be true.
