It follows, then, that the world has life, sense, reason, and understanding, and is consequently a Deity. But this shall soon be made more manifest by the operation of these very things which the world causes.

XVIII. In the mean while, Velleius, let me entreat you not to be always saying that we are utterly destitute of every sort of learning. The cone, you say, the cylinder, and the pyramid, are more beautiful to you than the sphere. This is to have different eyes from other men.
