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.

Through itself the soul arrives at all harmony that is perceptible in otherness-just as through what is internal the soul arrives at what is external.

With the senses man measures perceptible things, with the intellect he measures intelligible things, and he attains unto supra-intelligible things transcendently.

It has been asserted that there is a separate species on the earth to correspond with each one of the stars. Now if the earth provides in each species a focus for the action of each star, why may not a similar provision be made among other heavenly bodies that are subject to the action of their fellows?

All we know of the truth is that the absolute truth, such as it is, is beyond our reach.

The world has no circumference. It would certainly have a circumference if it had a centre, in which case it would contain within itself its own beginning and end; and that would mean that there was some other thing which imposed a limit to the world - another being existing in space outside the world. All of these conclusions are false. Since, then, the world cannot be enclosed within a material circumference and centre, it is unintelligible without God as its centre and circumference.

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.
