For that reason Derrida supposes that if he shows an error regarding Descartes in my text, on the one hand he will have shown the law that unconsciously rules everything that I could say about police regulations in the seventeenth century, unemployment in the classical era, Pinel's reform and psychiatric asylums of the nineteenth century; and on the other hand, as it is a matter of sin as much as it is of a slip, he will not have to show the precise effect of this error in the field of my study (how it affects the analysis that I make of the institutions or of medical theories): one single sin is enough to compromise a whole life without one having to show all the major and minor faults that developed from it.
