Famous quotes containing the words large and/or systems:
“Roughly speaking, any man with energy and enthusiasm ought to be able to bring at least a dozen others round to his opinion in the course of a year no matter how absurd that opinion might be. We see every day in politics, in business, in social life, large masses of people brought to embrace the most revolutionary ideas, sometimes within a few days. It is all a question of getting hold of them in the right way and working on their weak points.”
—Aleister Crowley (1875–1947)
“Not out of those, on whom systems of education have exhausted their culture, comes the helpful giant to destroy the old or to build the new, but out of unhandselled savage nature, out of terrible Druids and Berserkirs, come at last Alfred and Shakespeare.”
—Ralph Waldo Emerson (1803–1882)
