Once again, it seems that the nature of every principle of things is the Creator's secret. How does the air carry sound? how are animals formed? how do some of our limbs constantly obey our wills? what hand puts ideas in our memory, keeps them there as in a register, and pulls them out sometimes when we want them and sometimes in spite of ourselves? Our nature, the nature of the universe, the nature of the least plant, everything for us is sunk in a shadowy pit.
Man is an acting, feeling, thinking being: that is all we know of him: it is not given to us to know what makes us feel and think, or what makes us act, or what makes us exist. The acting faculty is as incomprehensible for us as the thinking faculty. The difficulty is less to conceive how a body of mud has feelings and ideas, than to conceive how a being, whatever it be, has ideas and feelings.
Here on one side the soul of Archimedes, on the other the soul of an idiot; are they of the same nature? If their essence is to think, they think always, and independently of the body which cannot act without them. If they think by their own nature, can the species of a soul which cannot do a sum in arithmetic be the same as that which measured the heavens? If it is the organs of the body which made Archimedes think, why is it that my idiot, who has a stronger constitution than Archimedes, who is more vigorous, digests better and performs all his functions better, does not think at all? It is, you say, because his brain is not so good. But you are making a supposition; you do not know at all. No difference has ever been found between healthy brains that have been dissected. It is even very probable that a fool's cerebellum will be in better condition than Archimedes', which has worked prodigiously, and which might be worn out and shrivelled.
Let us conclude therefore what we have already concluded, that we are ignoramuses about all first principles. As regards ignoramuses who pride themselves on their knowledge, they are far inferior to monkeys.
Now dispute, choleric arguers: present your petitions against each other; proffer your insults, pronounce your sentences, you who do not know one word about the matter.
