in Thoreau’s Journal:
He is the richest who has most use for nature as raw material of tropes and symbols with which to describe his life. If these gates of golden willows affect me, they correspond to the beauty and promise of some experience on which I am entering.
If I am overflowing with life, am rich in experience for which I lack expression, then nature will be my language full of poetry — all nature will fable, and every natural phenomenon be a myth. The man of science, who is not seeking for expression but for a fact to be expressed merely, studies nature as a dead language. I pray for such inward experience as will make nature significant.
