Natural Experiments

Famous quotes containing the words natural and/or experiments:

“If we have come to think that the nursery and the kitchen are the natural sphere of a woman, we have done so exactly as English children come to think that a cage is the natural sphere of a parrot: because they have never seen one anywhere else.”
—George Bernard Shaw (1856–1950)

“The true thrift is always to spend on the higher plane; to invest and invest, with keener avarice, that he may spend in spiritual creation, and not in augmenting animal existence. Nor is the man enriched, in repeating the old experiments of animal sensation; nor unless through new powers and ascending pleasures he knows himself by the actual experience of higher good to be already on the way to the highest.”
—Ralph Waldo Emerson (1803–1882)
