Famous quotes containing the word human:
“America does to me what I knew it would do: it just bumps me.... The people charge at you like trucks coming down on you—no awareness. But one tries to dodge aside in time. Bump! bump! go the trucks. And that is human contact.”
—D.H. (David Herbert)
“But nothing is better than a truth which appears not to have the semblance of truth. There is always something incomprehensible about the great heroic deeds performed by humanity because they rise so far beyond the mediocre measure of mere mortals; but it is always only because of the incredible feats that human beings have accomplished that humanity recovers its faith in itself.”
—Stefan Zweig (18811942)
