Superstructuralism has its roots in the human sciences. Ultimately it derives from the way in which linguistics and social anthropology were first set up, in France, around the beginning of the twentieth century. At that time, a new kind of fact – the human fact – swam into scientific ken, requiring the development of a new perspective. And this new perspective was no mere extension of the perspective of the natural sciences – though it took fifty years for the true magnitude of the divergence to emerge. Under this new perspective, the human sciences constituted themselves as unnatural sciences.
