Famous quotes containing the words flight and/or times:
“In all her products, Nature only develops her simplest germs. One would say that it was no great stretch of invention to create birds. The hawk which now takes his flight over the top of the wood was at first, perchance, only a leaf which fluttered in its aisles. From rustling leaves she came in the course of ages to the loftier flight and clear carol of the bird.”
—Henry David Thoreau (1817–1862)
“Why is it that we have enough memory to recollect the most minute circumstances of something that has happened to us, but not enough to remember how many times we have recounted them to the same person?”
—François, Duc De La Rochefoucauld (1613–1680)
