The second division of Mr. Gillespie's argument is also open to grave objection. Having demonstrated to his own satisfaction an infinite substance, and also having assumed in addition a finite substance, and having called the first an infinite "being"--perhaps from a devout objection to speak of God as substance--Mr. Gillespie seeks to prove that the infinite being is intelligent. He says: "Intelligence either began to be, or it never began to be. That is never began to be is evident in this, that if it began to be, it must have had a cause; for whatever begins to be must have a cause. And the cause of intelligence must be of intelligence; for what is not of intelligence can not make intelligence begin to be. Now intelligence being before intelligence began to be is a contradiction. And this absurdity following from the supposition that intelligence began to be, it is proved that intelligence never began to be: to wit, is of infinity of duration." Mr. Gillespie does not condescend to tell us why "what is not of intelligence cannot make intelligence begin to be;" but it is not unfair to suppose that he means that of things which have nothing in common one can not be the cause of the other. Let us apply Mr. Gillespie's argument to the material universe, the existence of which is to him so certain that he has treated it as a self-evident proposition. The material universe--that is, matter--either began to be, or it never began to be. That it never began to be is evident in this, that if it began to be, it must have had a cause; for whatever begins to be must have a cause. And the cause of matter must be of matter; for what is not of matter can not make matter begin to be. Now matter being before matter began to be is contradiction. And this absurdity following from the supposition that matter--i. e., the material universe--began to be, it is proved that the material universe never began to be--to wit, is of indefinite duration. The argument as to the eternity of matter is at least as logical as the argument for the eternity of intelligence. Mr. Gillespie may reply that he affirms the material universe to be finite in duration, and that by the argument for his proposition, part 2, he proves that the one infinite being (God) is the creator of matter. His words are:
