Famous quotes containing the words mental and/or deficiency:
“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)
“All rejection and negation indicates a deficiency in fertility: fundamentally, if only we were good plowland we would allow nothing to go unused, and in every thing, event, and person we would welcome manure, rain, or sunshine.”
—Friedrich Nietzsche (1844–1900)
