Famous quotes containing the word current:
“Absolutely speaking, Do unto others as you would that they should do unto you is by no means a golden rule, but the best of current silver. An honest man would have but little occasion for it. It is golden not to have any rule at all in such a case.”
—Henry David Thoreau (1817–1862)
