Famous quotes containing the words long and/or double:
“I have not yet learned to live, that I can see, and I fear that I shall not very soon. I find, however, that in the long run things correspond to my original idea,—that they correspond to nothing else so much; and thus a man may really be a true prophet without any great exertion. The day is never so dark, nor the night even, but that the laws at least of light still prevail, and so may make it light in our minds if they are open to the truth.”
—Henry David Thoreau (1817–1862)
“We are, I know not how, double within ourselves, with the result that we do not believe what we believe, and we cannot rid ourselves of what we condemn.”
—Michel de Montaigne (1533–1592)
