this is what he intends to imply by an enigmatical expression when he says that the man who was endowed by nature with a good disposition had two sons, twins: for every man has at the beginning simultaneously with his birth, a soul which is pregnant with twins, namely, good and evil, bearing the impression of both of them: but when it receives the blessed and happy part, then by the force of one single attraction it inclines to the good, never once leaning towards the other side, and never even wavering so as to appear to be balancing between the two.

But that soul which besides having a good natural disposition has also received a good education, and has been trained by the third mentioned person in the meditations of virtue, so that none of them float at random on the surface, but that they are all firmly glued and fixed in their places, as if united by some compact sinews, acquires health and acquires power, which are followed by a good complexion, owing to modesty, and also good health and beauty.
