Within itself the soul sees all things more truly than as they exist in different things outside itself. And the more it goes out unto other things in order to know them, the more it enters into itself in order to know itself.

Nor is the darkness of colour a proof of the earth's baseness; for the brightness of the sun, which is visible to us, would not be perceived by anyone who might be in the sun.

Just as all motion is from an unmovable cause, so everything divisible is from an indivisible cause. However, this visible, corporeal world is, assuredly, of a divisible nature, since what is corporeal is divisible. Therefore, this world is from an earlier, indivisible Cause.

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.

In humility alone lies true greatness, and knowledge and wisdom are profitable only in so far as our lives are governed by them.

A line partakes of the simplicity of a point more than does a surface; and a surface [partakes thereof more] than does a material object-as was evident. From this consideration of a point and a material object elevate yourself unto a likeness of True Being and of the universe; and by means of [this] quite clear symbolism [of a point] make a conjecture about what has been said.

Number, in consequence, includes all things that are capable of comparison. It is not then in quantity only that number produces proportion; it produces it in all things that are capable of agreement and differences in any way at all, whether substantially or accidentally.
