Famous quotes containing the words natural and/or nail:
“Knowledge has two extremes. The first is the pure natural ignorance in which all men find themselves at birth. The other extreme is that reached by great minds, who, having run through all that men can know, find they know nothing, and come back again to that same natural ignorance from which they set out; this is a learned ignorance which is conscious of itself.”
—Blaise Pascal (1623–1662)
“Every nail driven should be as another rivet in the machine of the universe, you carrying on the work.”
—Henry David Thoreau (1817–1862)
