Famous quotes containing the words guided and/or shells:
“Sometimes, when I compare myself with other men, it seems as if I were more favored by the gods than they, beyond any deserts that I am conscious of; as if I had a warrant and surety at their hands which my fellows have not, and were especially guided and guarded. I do not flatter myself, but if it be possible they flatter me.”
—Henry David Thoreau (18171862)
“It is not easy to make our lives respectable by any course of activity. We must repeatedly withdraw into our shells of thought, like the tortoise, somewhat helplessly; yet there is more than philosophy in that.”
—Henry David Thoreau (18171862)
