 In this group we can also include thesis 8, though with much less confidence, as it is the most obscure of the ten. We will tentatively suppose—following Harbsmeier (1998: 296) and Graham (1989: 79)—that this thesis too is based on infinitesimals. The paradox might then be explained in one of two ways. First, if the linked rings are thought of as circles, formed by points on a plane, then they have no thickness. They appear linked when viewed from above, but on the surface of the plane nothing blocks them from being pulled apart. The second explanation extends the same idea to three dimensions. If, as thesis 2 suggests, two three-dimensional rings are constituted by dimensionless points, then they can be pulled apart: since each point takes up no space, there is nothing preventing the rings from passing through each other. These interpretations are highly speculative, however. Without further contextual information, even if this sort of explanation makes sense of the paradox, we have no particular reason to believe it is correct.
