“The bud of the apple is desire, the down-falling gold,
The catbirds gobble in the morning half-awake
These are real only if I make them so. Whistle

Little flowerbut if I could understand
What you are, root and all, and all in all,

The view which regards him like a well, a reservoir full of possibilities, I call the romantic; the one which regards him as a very finite and fixed creature, I call the classical.”
—Thomas Ernest Hulme (18831917)
