For, since the image the sun imprints in the brain does not resemble the idea we have of it (as we have proved elsewhere), and as the soul does not perceive the motion the sun produces in the brain and in the fundus of the eyes, it is inconceivable that it should be able to determine precisely which among the infinite number of its ideas it would have to represent to itself in order to imagine or see the sun and to see it as having a given size.
