For in fact what is man in nature? A Nothing in comparison with the Infinite, an All in comparison with the Nothing, a mean between nothing and everything. Since he is infinitely removed from comprehending the extremes, the end of things and their beginning are hopelessly hidden from him in an impenetrable secret, he is equally incapable of seeing the Nothing from which he was made, and the Infinite in which he is swallowed up.
What will he do then, but perceive the appearance of the middle of things, in an eternal despair of knowing either their beginning or their end. All things proceed from the Nothing, and are borne towards the Infinite. Who will follow these marvellous processes? The Author of these wonders understands them. None other can do so.
Through failure to contemplate these Infinites, men have rashly rushed into the examination of nature, as though they bore some proportion to her. It is strange that they have wished to understand the beginnings of things, and thence to arrive at the knowledge of the whole, with a presumption as infinite as their object. For surely this design cannot be formed without presumption or without a capacity infinite like nature.
If we are well informed, we understand that, as nature has graven her image and that of her Author on all things, they almost all partake of her double infinity. Thus we see that all the sciences are infinite in the extent of their researches. For who doubts that geometry, for instance, has an infinite infinity of problems to solve? They are also infinite in the multitude and fineness of their premises; for it is clear that those which are put forward as ultimate are not self-supporting, but are based on others which, again having others for their support, do not permit of finality. But we represent some as ultimate for reason, in the same way as in regard to material objects we call that an indivisible point beyond which our senses can no longer perceive anything, although by its nature it is infinitely divisible.
