Seminar XXIV Final Sessions 1 - Lacan in Ireland

and to put that for you in black and white, I am going to show you what is atstake when one speaks about structure.It is a matter of something like that, namely, a holed torus – this I owe toPierre Soury – I mean that it is easy to complete this torus; you clearly seethat here there is, as one might say, the edge, if one can express oneself inthis way, so imprecisely, the edge of the hole which is in the torus and thatall of that is the body of the torus. [Fig IX-1, IX-2].It is not enough to draw this torus like that. For one sees that by holing thistorus at the same time one makes a hole in another torus. This is what isproper to the torus, for it is just as legitimate to draw the hole here and tomake the torus which is, as I might say, linked with that one. This indeed iswhy one can say that by holing a torus, one holes at the same time anothertorus which is the one which has with it a chain-like relationship.So then I am going to depict for you what one can draw here in terms of astructure which you see that by drawing it in two colours, I think it issufficiently evident that here, namely, the green in question, is inside the redtorus; but that on the contrary here you can see that the second torus isoutside. But that is not a second torus, since what is at stake is always thesame figure, but a figure which shows itself able to slide inside what I willcall the red torus, which slides while turning and which realises this toruslinked to the first one.106
