10. God is eternal: that is to say, he has had no beginning, and he will have no end. If he had had a commencement, he must have sprung from nothingness. Now, nothingness being nothing, can produce nothing; or, if he could have been created by another being anterior to himself, then this other being would be God. If one could suppose of him a commencement or an end, one would then be able to conceive a being having existed before him, or being able to exist after him, and thus one after the other even to infinitude.
