Famous quotes containing the words fuel and/or lead:
“I had an old axe which nobody claimed, with which by spells in winter days, on the sunny side of the house, I played about the stumps which I had got out of my bean-field. As my driver prophesied when I was plowing, they warmed me twice,—once while I was splitting them, and again when they were on the fire, so that no fuel could give out more heat. As for the axe,... if it was dull, it was at least hung true.”
—Henry David Thoreau (1817–1862)
“The only ways of enquiry that lead to knowledge ... the one way assuming that being is and that it is impossible for it not to be, is the trustworthy path, for truth attends it. The Other, that non-being is and that it necessarily is, I call a wholly incredible course, since thou canst not recognize not-being ... nor couldst thou speak of it, for though and being are the same things.”
—Parmenides (c. 515–480 B.C.)
