Natural Experiments

Famous quotes containing the words natural and/or experiments:

“We are educated in the grossest ignorance, and no art omitted to stifle our natural reason; if some few get above their nurses’ instructions, our knowledge must rest concealed and be as useless to the world as gold in the mine.”
—Mary Wortley, Lady Montagu (1689–1762)

“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)
