A disquisition on traffic-flow soon gives way to descriptions of the behaviour of light under observation (see Physics) and these and many other explanations of everything-at-once to an analysis of the relationship of Money to Economics and of “rational self-interest” to the Metaphysics of everyday life: “Everything we eat has been stolen from the mouths of others,” says the character known only as “The Doctor” (Ruffalo): “If we rob them of too much, we are responsible for their deaths… in a way, we are all murderers.” Saramago takes care to distinguish the sudden irruption of his “White Signus” from known varieties of blindness (see Medicine) and thereby to identify it as a “blindness of rationality” on the scale of a Disaster: this is, in other words, the catastrophe of the twentieth century writ large and described in chatty, free-ranging and precise style at the scale of the human, sometimes from the point of view of a particular human being, usually that of “The Doctor’s Wife” (Moore), sometimes at the level of the pack of blind humans for whom she is responsible and sometimes, boldly, directly and with no loss of dramatic focus, at the level of humanity’s shared past, as “you”, the reader, or “we” who are reading this, the world-changing Memes of a variety of thinkers, such as Friedrich Wilhelm Nietzsche (1844-1900) – “What is right and what is wrong are simply different ways of understanding our relationships with the others…” – or the critique by Sigmund Freud (1856-1939) of the relationship between Identity and self-presence, or, indeed, the assault by Martin Heidegger (1889-1976) on the ontology of Western discourse, part of which informed Derrida’s interrogation of “rationalist” thinkers and the French philosopher’s insistence on Linguistics as the best means of analysis of those cultures that define themselves by contrast with those they consider less “developed”, as in: “There’s no difference between inside and outside, between here and there, between the many and the few, between inside and outside, between what we’re living through and what we shall have to live through.” Every aspect of human behaviour is illuminated by the onset of “white” blindness, from the necessary delusions of human relationships to the deep-seated affiliation between fascism and the imposition of Sex on the unwilling: the breakdown of the social contract here reveals what the social contract was obscuring, a form of impaired vision from which we all, to greater or lesser extent, suffer. “It is beginning to emerge that this distinction between nature and society (‘nature’ and ‘culture’ seem preferable to us today), while of no historical significance, does contain a logic, fully justifying its use by modern sociology as a methodological tool,” Anthropologist Claude Lévi-Strauss wrote in Les Structures élémentaires de la parenté (1949 trans James Bell, John von Sturmer and Rodney Needham as The Elementary Structures of Kinship 1969), but Saramago, like Derrida, goes beyond the convenience of this distinction to reveal how deeply human instincts are embedded in culture and now intrinsic cultural definitions are to descriptions of apparently natural behaviours:-
