Famous quotes containing the words natural and/or science:
“There is an universal tendency among mankind to conceive all beings like themselves, and to transfer to every object, those qualities, with which they are familiarly acquainted, and of which they are intimately conscious. We find human faces in the moon, armies in the clouds; and by a natural propensity, if not corrected by experience and reflection, ascribe malice or good-will to every thing, that hurts or pleases us.”
—David Hume (1711–1776)
“Consider the China pride and stagnant self-complacency of mankind. This generation inclines a little to congratulate itself on being the last of an illustrious line; and in Boston and London and Paris and Rome, thinking of its long descent, it speaks of its progress in art and science and literature with satisfaction.... It is the good Adam contemplating his own virtue.”
—Henry David Thoreau (1817–1862)
