Just as essential memory, essential intelligence and essential will produce their likenesses in B.C.D., they likewise produce their likenesses in the virtues. And this is because the virtues were created and differentiated in plurality, and joined together in substantial unity. And as they produce their likenesses in the virtues that agree with being, so they also produce their unlikenesses in the vices that agree with nothing. Thus there are two parts to the propositions of figure V. in this book, one for the virtues and one for the vices. There are seven virtues with three propositions each, which gives twenty-one propositions in the first part; and as there are seven vices with three propositions each, the second part has as many propositions as the first, which makes twice twenty-one, or forty-two propositions in all. So there are forty-two propositions in V., and the first part is dealt with first, to show how the soul's being acquires its likeness in the virtues, and the second part comes afterward. So let us begin first with the propositions on faith, and follow with the other virtues and vices in sequence.
