Famous quotes containing the words thought and/or experiments:
“It must not be thought that the cowardly feeling of caution and uneasy self-preservation is innate in the English character. It is the consequence of a corpulence derived from wealth and of the training of all thoughts and passions for acquisitiveness.”
—Alexander Herzen (1812–1870)
“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)
