Famous quotes containing the word substance:
“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.”
—Rudolf Arnheim (b. 1904)
