The term A[rt] resembles a chemist's graduated glass. Each age contributes its own quantity: for example, 5 grams of the perfume 'Coty' to tickle the nostrils of the fine gentry. Or another example, 10 cc of sulfuric acid to be thrown into the face of the ruling classes. Or, 15 cc: of some kind of metallic solution that later changes into a new source of light.. ..[as Lissitzky goes on to say] This A[rt] is an invention of the mind, i.e. a complex, where rationality is fused with imagination.
