One of the modern Mutakallemim thought that he had found a very good argument, much better than any advanced hitherto, namely, the argument based on the triumph of existence over non-existence. He says that, according to the common belief, the existence of the Universe is merely possible; for if it were necessary, the Universe would be God—but he seems to forget that we are at issue with those who, whilst they believe in the existence of God, admit at the same time the eternity of the Universe.—The expression “A thing is possible” denotes that the thing may either be in existence or not in existence, and that there is not more reason why it should exist than why it should not exist. The fact that a thing, the existence of which is possible, actually does exist—although it bears the same relation to the state of existence as to that of non-existence—proves that there is a Being which gave the preference to existence over non-existence. This argument is very forcible; it is a modified form of the foregoing argument which is based on the theory of determination. He only chose the term “preference” instead of “determination,” and instead of applying it to the properties of the existing being he applies it to “the existence of the being itself.” He either had the intention to mislead, or he misunderstood the proposition, that the existence of the Universe is possible. Our opponent who assumes the eternity of the Universe, employs the term “possible,” and says, “the existence of the Universe is possible” in a sense different from that in which the Mutakallem applies it, as will be explained below. Moreover it may be doubted whether the conclusion, that the Universe owes its origin to a being which is able to give preference to existence over non-existence, is correct. For we may apply the terms “preference” and “determination” to anything capable of receiving either of two properties which are contrary or opposed to each other; and when we find that the thing actually possesses one property and not the other, we are convinced that there exists a determining agent. E.g., you say that a piece of copper could just as well be formed into a kettle as into a lamp; when we find that it is a lamp or a kettle, we have no doubt that a deciding and determining agent had advisedly chosen one of the two possible forms; for it is clear that the substance of copper existed, and that before the determination took place it had neither of the two possible forms which have just been mentioned. When, however, it is the question whether a certain existing object is eternal, or whether it has passed from non-existence into existence, this argument is inadmissible; for it cannot be asked who decided in favour of the existence of a thing, and rejected its non-existence, except when it has been admitted that it has passed from non-existence into existence; in the present case this is just the point under discussion. If we were to take the
