Is this crossed connection-making the result of mere artifice or play? There is certainly play * in such a movement, and this chiasmus is authorized, even prescribed, by the ambivalence of the pharmakon. Not only by the polarity good/evil, but by the double participation in the distinct regions of the soul and the body, the invisible and the visible. This double participation *, once again, does not mix together two previously separate elements; it refers back to a same that is not the identical, to the common element or medium of any possible dissociation ( 127).
