Atheism’s appeal to logic

After reading all the strained logic (on the order of proving that bumblebees can’t fly) used to prove that evolution is impossible, even though we observe it in nature (and therefore Goddidit), it’s a relief to read a fairly straightforward logical argument in the other direction. This one is from Inimicus Dei: “Is the Concept of a Necessary Being Logical?

…A necessary being, by virtue of it being necessary, must exist in all possible worlds. Because God is a necessary being, he must exist in all possible worlds, and since our world is a possible world, then God must exist in our world…

Ask yourself this: how many possible worlds are there? The answer: there’s an infinite number of them. Indeed, you can posit a world with only one atom, a world with two atoms, one with three atoms, etc. By merely counting atoms, you arrive at an infinite number of worlds. (It is important to note here that by “world” I do not necessarily mean “universe” as in the time-space/matter-energy kind of universe we live in. It could be a non material world or whatever else. The only condition is that the world must obey the laws of logic, thus the term “possible.”)

Now when faced with infinity, one can be certain of one thing: everything – and I do mean everythingwill happen at least once. That means that there will be a world with one atom, a world with two atoms… and – tadaaaaaa! – a world with no atoms at all! (You know where I’m going with this, don’t you?)

Similarly, if you have an infinite number of possible worlds, then at least one of them will be without a god! That is required by logic. It follows then that the concept of necessary being is flawed, as it is contradicted by logic. Just as a bachelor cannot be married, a being cannot be necessary.

Therefore, God’s existence has not been demonstrated.

    Actually, it depends on what “necesary being” means. Generally it comes down to the argument that you need God to support logic… yeah, it is a fun one.

    The problem is that he isn’t offering any justification for his statement and thus it is worthless.

  2. LauLuna Says:

    So, according to inimicus dei, literally everything must happen in some possible world. Even that two stones and two stones add up to five stones?

    If possible worlds are to be possible, they better don’t contradict necessary truths.

    Now, if God exists, its existence is necessary and ‘God exists’ is a necessary truth. We shouldn’t expect it to be contradicted by any world that could be called a possible world.

    The argument of inimicus dei boils down to absolutely nothing.

      I don’t think you read the argument very carefully. If God doesn’t exist in some world, then a deity is not necessary. Of course, I know that philosophy’s not reality. Many philosophical proofs of deity slip into their axioms the assumption that deities are needed, thus fixing the conclusion before they even make the argument. It’s much much more significant that there has never been a scrap of unequivocal evidence for any deity, just a lot of rationalization.

    Just from what was posted, the only variables listed were material. From that I suppose variations in energy could cause two “worlds” to be deemed different.

    But in most cases “God” is not conceived as a material entity. At best the conclusion of this essay should be that “necessary beings” can not be material (or at least not rooted in matter).

    And as God is a necessary being, he is not rooted in matter. And thus it is possible (and here my rudimentary philosophy knowledge breaks down) that God is unobservable in the material world. “Revelation,” of course, cannot yet be precluded.
