And, as to my part, quoth I, O Philippus! I am not only much moved, but also ashamed, considering my youth, in the presence of so many wise and grave personages, to appear as if I endeavored by sophistry to impose upon them, and to destroy and evacuate what sage and holy men have determined concerning the divine nature and power. But though I am young, yet Plato was old and wise as you are, and he shall be my example and advocate in this case. He reprehended Anaxagoras for applying himself too much to natural causes, always following and pursuing the necessary and material cause of the passions and affections incident to bodies, and omitting the final and efficient, which are much better and more considerable principles than the other. But Plato either first, or most of all the philosophers, hath joined both of these principles together, attributing to God the causality of all things that are according to reason, and yet not depriving matter of a necessary or passive concurrence; but acknowledging that the adorning and disposing of all this sensible world does not depend on one single and simple cause, but took its being from the conjunction and fellowship of matter with reason. This may be illustrated by the works of art; as, for example, without going any further, the foot of the famous cup which is amongst the treasure of this temple, which Herodotus calls a Hypocrateridion, that has for the material causes fire and iron, and pliableness by means of fire, and the tincture in water, without which such a piece of work could not be wrought. But the principal cause, and that which is most properly so called, which wrought by all these, was art and reason. And we see the name of the artist set on all such pieces, according to that, ’Twas Thasian Polygnotus, Aglaophon’s son, That drew this draught of conquer’d Ilium. But yet, without colors mixed and confounded with one another, it had been impossible to have done a piece so pleasing to the eye. Should one come then and enquire into the material cause, searching into and discoursing concerning the alterations and mutations which the vermilion receives mixed with ochre, or the ceruse with black, would he thereby lessen the credit of the painter Polygnotus? And so he that shall discourse how iron is both hardened and mollified, and how, being softened in the fire, it becomes obedient to them who by beating it drive it out in length and breadth; and afterwards, being plunged into fresh water, by the coldness of it becomes hardened and condensed after it was softened and rarefied by the fire, and acquires a firmness and temper which Homer calls the strength of the iron,—does he, because of this, e’er the less attribute the cause of the work to the workman? I do not think he does; for those who examine the virtues and properties of medicinal drugs do not thereby condemn the art of physic. Just as when Plato says that we see because the light of the eye is mixed with the clearness of the sun, and that we hear by the percussion of the air, yet this does not hinder but that we have the faculty of seeing and hearing from Divine Providence.
