Famous quotes containing the word science:
“The great pagan world of which Egypt and Greece were the last living terms ... once had a vast and perhaps perfect science of its own, a science in terms of life. In our era this science crumbled into magic and charlatanry. But even wisdom crumbles.”
—D.H. (David Herbert)
“Art is the beautiful way of doing things. Science is the effective way of doing things. Business is the economic way of doing things.”
—Elbert Hubbard (1856–1915)
