It is not an intelligent being such as I am, who directed the formation of this world, for I cannot form a mite; therefore this world is the work of a prodigiously superior intelligence.

Does this being, who possesses intelligence and power in so high a degree, exist necessarily? It must be so, for either the being received existence from another, or from its own nature. If the being received existence from another, which is very difficult to imagine, I must have recourse to this other, and this other will be the prime author. To whichever side I turn I have to admit a prime author, potent and intelligent, who is such necessarily by his own nature.

Did this prime author produce things out of nothing? that is not imaginable; to create out of nothing is to change nothing into something. I must not admit such a production unless I find invincible reasons which force me to admit what my intelligence can never comprehend.

All that exists appears to exist necessarily, since it exists. For if to-day there is a reason for the existence of things, there was one yesterday, there was one in all time; and this cause must always have had its effect, without which it would have been during eternity a useless cause.

But how shall things have always existed, being visibly under the hand of the prime author? This power therefore must always have acted; in the same way, nearly, that there is no sun without light, so there is no movement without a being that passes from one point of space to another point.

There is therefore a potent and intelligent being who has always acted; and if this being had never acted, of what use would his existence have been to him?

All things are therefore eternal emanations of this prime author.

But how imagine that stone and mud are emanations of the eternal Being, potent and intelligent?

Of two things one, either the matter of this stone and this mud exist necessarily by themselves, or they exist necessarily through this prime author; there is no middle course.

Thus, therefore, there are only two choices to make, admit either matter eternal by itself, or matter issuing eternally from the potent, intelligent eternal Being.

But, either subsisting by its own nature, or emanated from the producing Being, it exists from all eternity, because it exists, and there is no reason why it should not have existed before.

If matter is eternally necessary, it is therefore impossible, it is therefore contradictory that it does not exist; but what man can affirm that it is impossible, that it is contradictory that this pebble and this fly have not existence? One is, nevertheless, forced to suppress this difficulty which astonishes the imagination more than it contradicts the principles of reasoning.
