Abstract

Famous quotes containing the word abstract:

    If we take in our hand any volume; of divinity or school metaphysics, for instance; let us ask, Does it contain any abstract reasoning concerning quantity or number? No. Does it contain any experimental reasoning, concerning matter of fact and existence? No. Commit it then to flames: for it can contain nothing but sophistry and illusion.
    David Hume (1711–1776)

    All abstract sciences are nothing but the study of relations between signs.
    Denis Diderot (1713–1784)

    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)
