Of course, most don’t just stop and say this proves that there is a god, but that this proves in fact the Christian God; I haven’t heard the argument used by Muslim apologists, or any other religion for that matter, though they could probably be just as able to say the same things. To get to this position about the existence of the Christian concept of the divine requires more than just the existence of logic, but since they think they already have logic on their side because of their theism, the rest will follow for them, either by faith or further argumentation, such as the historicity of the Resurrection.
What we can see here is that in fact the notion of forcing the atheist to account for reason itself is simply a debating tactic, something to trip up the debater from showing the errors in the others belief system. The entire notion of pressupositionalist arguments is to say that since there is something wrong, anything wrong, with my world view, then one must default to some religious view and say goddidit with great frequency. The standard of perfection or theism is an amazingly high standard, one that cannot be met by anyone because there is not enough computing power in the universe to see if there are any possible contradictions between all the views a person may take. Besides consistency does not mean that it is necessarily true; if my belief that the world is spherical contradicts some political policy I have adhere to, it does not follow then that all is false, that the world is not necessarily round. Besides, the concept of goddidit for all answers can be consistent, but if there is no God, then the world view must be in error.
But perhaps we should take up the gauntlet of the arguers, take up the case that logic is supported in some fashion by a god, or any being for that matter. It seems that the statement that logic is “true” because god said so seems to beg some form of the old Euthyphro Dilemma:
or does god say something is logical because it is so?
But perhaps you don’t have a problem with logic, and morality for that matter, being arbitrary. Well, here is an interesting question: since god created the laws of logic, then can god break the law of non-contradiction? Suppose no–if that is the case, then that seems to say that logic makes the god subservient to the creation, which seems to be an unlikely situation. More interestingly, suppose yes–if god can break the law of non-contradiction, then god can exist and not exist at the same time. Therefore, that god does not exist is a true statement about god. Ergo, god does not exist. What this means that if god is in fact powerful enough to break the laws of logic, then god does not exist. With such a twist, it seems to be untenable to say that anything is the source of logic.
This is certainly fun to take the theists argument and make it mean that god does not exist, but one can still charge that logic is still not supported and so to use it cannot be meaningful to one that denies it. So, can logic be accounted for?
If it is false, it is true.
It would seem then that logic accounts for itself just fine; the denial of it is impossible and to declare its need for support from beyond itself will enter the paradox of its own nonexistence. So, if someone tries to badger on about this, just point out that it cannot be said to be otherwise, unlike gods. It is possible to say “there are no gods” without it being internally contradictory; this cannot be said about non-contradiction. Hence, there is nothing left to prove.
Isn’t it good to know smart people’s arguments?
