Written culture itself, up to its recently implemented universal literacy, has had sharply selective effects. It has riven its host societies and formed a divide between literate and illiterate human beings, whose unbridgeability almost attained the firmness of a species differentiation. If one wished, despite Heidegger's dissuasions, to speak anthropologically again, then the human beings of historical times could be defined as the animals of whom some can read and write while the others cannot. From here it is only a single step, if a demanding one, to the thesis that human beings are the animals of whom some breed those like them, while the others are bred--a thought that belongs to the pastoral folklore of Europeans since the time of Plato's reflections on education and the state. Something of this is still heard in Nietzsche's statement that few of the human beings in the small houses will, but most are willed. But to be only willed means to exist merely as an object, not as a subject, of selection.
