Famous quotes containing the words surface and/or porous:
“All beauties contain, like all possible phenomena, something eternal and something transitory,—something absolute and something particular. Absolute and eternal beauty does not exist, or rather it is only an abstraction skimmed from the common surface of different sorts of beauty. The particular element of each beauty comes from the emotions, and as we each have our own particular emotions, so we have our beauty.”
—Charles Baudelaire (1821–1867)
“Does art reflect life? In movies, yes. Because more than any other art form, films have been a mirror held up to society’s porous face.”
—Marjorie Rosen (b. 1942)
