Famous quotes containing the words controlled and/or experiments:

“Babies control and bring up their families as much as they are controlled by them; in fact ... the family brings up baby by being brought up by him.”

“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)
