O argumento geral da intuição (ou de intuição, do inglês "General Argument from Intuition."[1]) é um argumento para a existência de Deus. Sobre ele, o filósofo cristão Alvin Plantinga diz:

We have many kinds of intuitions: (1) logical (narrow sense and broad sense):. the intuitions codified in propositional modal logic--if it could be the case that the moon is made of green cheese, then it is necessary that that could be so; moral, (2) arithmetical, set theoretical and mathematical generally, (3) moral, (4) philosophical (Leib's Law; there aren't any things that do not exist; sets don't have the property of representing things as being a certain way; neither trees nor numbers are neither true nor false; there are a great number of things that are either true or false; there is such a thing as positive epistemic status; there is such a property as being unpunctual; and so on.) You may be inclined to think that all or some of these ought to be taken with real seriousness, and give us real and important truth. It is much easier to see how this could be so on a theistic than on a nontheistic account of the nature of human beings.

At the Mississippi Philoso Association Meeting in Nov., l986, Robert Holyer read a paper nicely developing this argument, and referring to John Beversluis' book, who attacks the argument, but in a mean spirited way and not with much success. This argument along with Augustine's "Our hearts are restless til they rest in thee, O God."

A couple of more arguments: (1) the argument from the causal theory of knowledge: many philosophers think there is a problem with our alleged knowledge of abstract objects in that they think we can't know truths about an object with which we are not in the appropriate causal relation. They then point out that we are not in much of any causal relation with abstract objects, and conclude, some of them, that there is a real problem with our knowing anything about abstract objects. (e.g., Paul enacerraf.) But if we think of abstract objects as God's thoughts, then he is in causal relation with them, and also with us, so that there should be no problem as to how it is that we could know something about them. (On the causal theory of knowledge, if you think of abstract objects as just there, and as not standing in causal relations, then the problem should really be that it is hard to see how even God could have any knowledge of them.)

There is another realism anti-realism argument lurking here somewhere, indicated or suggested byWolterstorff's piece in the Tomberlin metaphysics volume. It has to do with whether there are really any joints in reality, or whether it might not be instead that reality doesn't have any joints, and there are no essential properties of objects. Instead, there is only de dicto reality (this could be the argument from de re modality) with all classifications somehow being done by us. Interesting. Also another topic for Christian philosophy.

Another argument, brought to my attention by Nick Wolterstorff: the Chomsky argument from language learning. look this us. Where does C say any such thing? And where exactly does it go? Does it go with the KW plus quus argument?

Another argument… Thomas Nagel, the view from nowhere 78ff. Thinks it amazing that there should be any such thing as the sort of objective thinking or objective point of view that we do in fact have. Perhaps it is really amazing only from a naturalist point of view. He says he has no explanation. Maybe you find it amazing, maybe you don't. (I'm not sure I see why it is amazing yet.) He argues cogently that there is no good evolutionary explanation of this: first, what needs to b explained is the very possibility of this, and second, supposed that is explained, he goes on to argue that evolution gives us no good explanation of our higher mental abilities. The question is whether the mental powers necessary for the making of stone axes, and hunter-gatherer success are sufficient for the construction of theories about sub atomic particles, proofs of Gödel's theorem, the invention of the compact disc, and so on. He thinks not. So he is really on to something else: not so much 'objective thinking' as higher mental powers involved in these striking intellectual accomplishments.

The evolutionary explanation would be that intellectual powers got started by going along for the ride, so to speak, and then turned out to be useful, and were such that improvements in them got selected when we came down from the trees. (At that point a bigger brain became useful (Don't whales have an even bigger one?). A sort of two part affair, the first part being accidental. So then the second part would be selected for survival value or advantage. But of course the question is whether this gives the slightest reason to think these theories have any truth to them at all. And he fails to mention the fact that all that really gets selected is behavior; there are various combinations of desire and belief that can lead to adaptive actions even if the belief is completely mistaken.[1]
