The heart of Chatton’s account involves clarifying the idea of ‘composition’. To the obvious question of how something continuous could be composed of finitely many indivisibles and not be gappy, Chatton responds that continua are only potentially divisible into indivisibles, not actually so divisible, so there are no actually existing indivisibles in this sense. He rejects the model discussed above, in which beads compose a necklace; in that example the beads have a separate existence in act, and each has a length which it lends to the necklace when strung onto it. But Chattonian indivisibles do not exist independently and then, when added together, yield continuous lengths. Existing only potentially, they compose the line in only in the reduced sense of being a part. Chatton’s point is that any potential division of the line is in fact finite, and can yield at most finitely many parts. His conviction is not that there exist indivisible discrete building-blocks of material things, but that there is some level of division that is basic or lowest, a theoretical maximum. The indivisible elements at the theoretical maximum can, in the reduced sense explained above, be said to compose the continuous whole they are in because, as indivisibles, they do not have part touching parts, but instead they have nothing between them; they are immediate to each other and distinct in place.
