Famous quotes containing the words test and/or substance:
“It is the test of a novel writer’s art that he conceal his snake-in-the-grass; but the reader may be sure that it is always there.”

“Just as a chemist “isolates” a substance from contaminations that distort his view of its nature and effects, so the work of art purifies significant appearance. It presents abstract themes in their generality, but not reduced to diagrams.”
