If matter is eternally necessary, it is in consequence impossible--it is contradictory, that it should not exist; but what man can assure you that it is impossible, that it is contradictory, that this fly and this flint have not always existed? We are, however, obliged to swallow this difficulty, which more astonishes the imagination than contradicts the principles of reasoning. Indeed, as soon as we have conceived that all has emanated from the supreme and intelligent being; that nothing has emanated from him without reason; that this being, always existing, must always have acted; that, consequently, all things must have eternally proceeded from the bosom of his existence--we should no more be deterred from believing the matter of which this fly and flint are formed is eternal, than we are deterred from conceiving light to be an emanation of the all-powerful being. Since I am an extended and thinking being, my extent and thought are the necessary productions of this being. It is evident to me that I cannot give myself extent or thought. I have, therefore, received both from this necessary being. Can he have given me what he has not? I have intelligence; I am in space; therefore, he is intelligent and is in space. To say that the Eternal Being, the All-Powerful God, has from all time necessarily filled the universe with His productions, is not taking from Him His free-will; but on the contrary, for free-will is but the power of acting. God has always fully acted; therefore God has always used the plenitude of His liberty. The liberty which we call indifference is a word without an idea--an absurdity; for this would be to determine without reason; it would be an effect without a cause. Therefore God cannot have this pretended free-will, which is a contradiction in terms. He has, therefore, always acted by the same necessity which causes His existence. It is, therefore, impossible for the world to exist without God; it is impossible for God to exist without the world. This world is filled with beings who succeed each other; therefore, God has always produced beings in succession. These preliminary assertions are the basis of the ancient eastern philosophy, and of that of the Greeks. We must except Democritus and Epicurus, whose corpuscular philosophy has combated these dogmas. But let us remark that the Epicureans were founded on an entirely erroneous philosophy, and that the metaphysical system of all the other philosophy subsisted with all the physical systems. All nature, except the void, contradicts Epicurus, and no phenomenon contradicts the philosophy which I explain. Now, a philosophy which agrees with all which passes in nature, and which contents the most attentive mind, is it not superior to all other unrevealed systems?
