### Famous quotes containing the word hour:

“That *hour* in the life of a man when first the help of humanity fails him, and he learns that in his obscurity and indigence humanity holds him a dog and no man: that *hour* is a hard one, but not the hardest. There is still another *hour* which follows, when he learns that in his infinite comparative minuteness and abjectness, the gods do likewise despise him, and own him not of their clan.”

—Herman Melville (1819–1891)
