In short, if we wish to compare our ideas to the objects we see, we will be able to judge: that the sun is the center of the vortex; that the corporeal light it dispenses in all directions is nothing but the continual effort of the tiny balls, which tend to recede from the center of the vortex; and that this light must be transmitted instantaneously through immense spaces because, since all space is full of these balls, one cannot be pressed without all the others next to it being pressed.
