Fig. 3 adds the new quality \(\mathrm{d}q\) to detail what changes from Fig. 1 to Fig. 2.

The quality \(\mathrm{d}q\) is a #DifferentialQuality. Its absence or presence qualifies the absence or presence of change in another quality. Like any quality it is marked in the diagram by a “circle”, here distinguishing the parts of \(X\) inside and outside the region \(\mathrm{d}Q.\)

The quality \(\mathrm{d}q\) is a #DifferentialQuality. Its absence or presence qualifies the absence or presence of change in another quality. Like any quality it is marked in the diagram by a “circle”, here distinguishing the parts of \(X\) inside & outside the region \(\mathrm{d}Q.\)

Figure 3 augments Figure 1 with a new quality \(\mathrm{d}q\) to account for the transition from Figure 1 to Figure 2.

The quality \(\mathrm{d}q\) is a #DifferentialQuality — its absence or presence qualifies the absence or presence of change occurring in another quality. Like any quality it is marked in the diagram by a “circle”, in this case distinguishing the portions of \(X\) inside and outside the region \(\mathrm{d}Q.\)
