Famous quotes containing the word human:
“Doubtless, we are as slow to conceive of Paradise as of Heaven, of a perfect natural as of a perfect spiritual world. We see how past ages have loitered and erred. “Is perhaps our generation free from irrationality and error? Have we perhaps reached now the summit of human wisdom, and need no more to look out for mental or physical improvement?” Undoubtedly, we are never so visionary as to be prepared for what the next hour may bring forth.”
—Henry David Thoreau (1817–1862)
“In my short experience of human life, the outward obstacles, if there were any such, have not been living men, but the institutions of the dead.”
—Henry David Thoreau (1817–1862)
“We are as great as our belief in human liberty—no greater. And our belief in human liberty is only ours when it is larger than ourselves.”
—Archibald MacLeish (1892–1982)
