  Central to the unfolding argument in the Dialoghi is the concept of ocular power (forza oculare). In the first dialogue, Judah describes two modes of apprehending spiritual matters. The first is through the faculty of sight and the second through the  intellect.[34]   For the eye, like the intellect, is illumined by means of light, thereby establishing a relationship between the eye, the object seen, and the space that separates  them.[35]   Just as the sun supplies light to the eye, the divine intellect illumines the human intellect during the act of intellection. It is light, then, that enables us to “comprehend all the beautiful shining objects of the corporeal  world.”[36]  Sight becomes the model by which we engage the universe: it is what makes knowledge possible since it is only through vision of tangible particulars that we acquire knowledge of intelligibles.
