Nothing about his life is more strange to [man] or more unaccountable in purely mundane terms than the stirrings he finds in himself, usually fitful but sometimes overwhelming, to look beyond his animal existence and not be fully satisfied with its immediate substance. He lacks the complacency of the other animals: he is obsessed by pride and guilt, pride at being something more than a mere animal, built at falling short of the high aims he sets for himself.
Lewis MumfordIt has not been for nothing that the word has remained man's principal toy and tool: without the meanings and values it sustains, all man's other tools would be worthless.
Lewis Mumford
