  The aim of D3 is to establish, for a variety of different properties F, that if the one is, then the others are both F and con-F. Within D3, there are seven Arguments with the following Conclusions: If the one is, then the others are not the one (D3A1C), the others have parts (D3A2C1), the others are a whole (D3A2C2 and D3A3C2), the others are one (D3A2C3 and D3A3C1), the whole and the part of the others are many (D3A4C), the whole and the part of the others are unlimited in multitude (D3A5C1), the whole and the part of the others are unlimited (D3A5C2), the whole and the part of the others are limited (D3A6C), each of the others is like itself (D3A7C1), each of the others is like each of the others other than itself (D3A7C2), each of the others is unlike itself (D3A7C3), and each of the others is unlike each of the others other than itself (D3A7C4). There is also the promise of a number of Arguments establishing results of the form: If the one is, then the others are both F and con-F.
