Famous quotes containing the word nature:
“It was his nature to suppose,
To receive what others had supposed, without
Accepting. He received what he denied.
But as truth to be accepted, he supposed
A truth beyond all truths.”
—Wallace Stevens (1879–1955)
“Our treasure lies in the beehive of our knowledge. We are perpetually on the way thither, being by nature winged insects and honey gatherers of the mind.”
