The Social History of Art, Volume I. From Prehistoric Times to the Middle Ages, 1999, Chapter IV. The Middle Ages
“In the writings of such "pagan" philosophers as Plutarch and Porphyry we find a humanitarian ethic of the most exalted kind, which, after undergoing a long repression during medieval churchdom, reappeared, albeit but weakly and fitfully at first, in the literature of the Renaissance, to be traced more definitely in the eighteenth century school of "sensibility." But it was not until after the age of Rousseau, from which must be dated the great humanitarian movement of the past century, that Vegetarianism began to assert itself as a system, a reasoned plea for the disuse of flesh-food.”

The importance of Street Art comes from the fact that this art is available to everyone anywhere, is made from any media using any technique. Street Art lets you do whatever you want in the way you want and do it without asking anybody. This freedom is what makes Street Art unique.
