“Poetry, at all times, exercises two distinct functions: it may reveal, it may unveil to every eye, the ideal aspects of common things ... or it may actually add to the number of motives poetic and uncommon in themselves, by the imaginative creation of things that are ideal from their very birth.”
—Walter Pater (1839–1894)
“I have no designs on society, or nature, or God. I am simply what I am, or I begin to be that. I live in the present. I only remember the past, and anticipate the future. I love to live.”
