Famous quotes containing the word nature:
“Put shortly, these are the two views, then. One, that man is intrinsically good, spoilt by circumstance; and the other that he is intrinsically limited, but disciplined by order and tradition to something fairly decent. To the one party man’s nature is like a well, to the other like a bucket. 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 (1883–1917)
“And then, Sir, there is this consideration, that if the abuse be enormous, Nature will rise up, and claiming her original rights, overturn a corrupt political system.”
—Samuel Johnson (1709–1784)
