 A critical underlying difference between the succession and addition theorists is the question over whether forms are indivisible or can be perpetually broken down into smaller parts. The succession theorist thinks forms are indivisible and do not contain parts (Sylla 1973, 231). But Adam Wodeham, in harmony with his general anti-atomists position, argues that forms can be infinitely divided. In this way, there is no trouble in saying that, through addition, a new form is created, which contains the old form as one of its parts.
