In one of the essays in Mythologies, Barthes acknowledges the "quick-change artistry of plastic" but then goes on to say that "plastic is, all told, a spectacle to be deciphered: the very spectacle of its end-products" (with spectacle being a somewhat technical term meaning "the interplay of action, representation and alienation in man and in society").
For Barthes, plastic becomes the ultimate sign of transmutation: "Plastic, sublimated as movement, hardly exists as substance." In fact:
"The hierarchy of substances is abolished: a single one replaces them all: the whole world can be plasticized, and even life itself since, we are told, they are beginning to make plastic aortas."
