A given circle cannot be so true that a truer one cannot be found; and the movement of a sphere at one moment is never precisely equal to its movement at another, nor does it ever describe two circles similar and equal, even if from appearances the opposite may seem true.

The rational is apprehended through the intellect, however, the intellect is not found in the region of the rational; the intellect is as the eye and the rational as the colors.

Those, however, who saw that one cannot attain wisdom and perennial intellectual life, unless it be given through the gift of grace, and that the goodness of the Almighty God is so great that He hears those who invoke His name, and they gain salvation, became humble, acknowledging that they are ignorant, and directed their life as the life of one desiring eternal wisdom. And that is the life of the virtuous, who proceed in the desire for the other life, which is commended by the saints.
