Thus, I think it's reasonable to ask, what evidence for theism would you take as being sufficient. Put another way, what evidence would cause you to move from atheism to theism?
This is a fairly common question in this forum; I've seen many possible answers that all boil down to the observable universe would have to be vastly different from the way it is. For instance, if everyone who professed belief in God gave closely similar descriptions of what God wanted of humanity, and if there was one commonly accepted set of scriptures, and if there was clear and consistent advantage accruing to those who professed belief, that would be a good start. (There would still be problems, mind you, but those problems would concern the *nature* of God and not his existence.) In the world we actually live in, the concept of a god- in particular, a benevolent, omniscient, omnipotent one- is violently self-contradictory. |

Similarly, the assertion that God is omniscient may seem disarmingly simple at first blush, until we stop to reflect on what it would mean for a being to be omniscient. It would mean that He has an infinite “database” of information – in fact, its size would have to exceed any cardinality (which is vast indeed). And then there must be some sort of mechanism (not physical presumably, but I don’t know of any adequate word) to “search” this database (at infinite speed of course) to retrieve any desired information. There must be a “central processor” of some kind capable of correlating infinite amounts of information instantaneously (or at least in a finite amount of time – and when one is dealing with infinities the difference is essentially nonexistent). And so on. The “omniscience and “omnibenevolence” properties similarly imply vast, incredibly complicated capabilities which must be realized somehow. This is what I mean by saying that the God hypothesis is infinitely complex. These “simple” words cover a heck of a lot of ground. Quote:

At any rate, since reliance on divine revelation is clearly not part of the basic “rational strategy”, it would have to be justified via this strategy before it could be considered rational. Quote:

Am I to understand then...
(Hi Kuyper)...that Platinga, and you, are launching an argument that the foundational attributes of ones ontology needn't be rational or supported with "sufficient evidence" to justify ones beliefs?
I ask this in response to what you said here: My argument is, yes. In this respect, I agree with Plantinga's project in his "Warrented Christian Belief". But even he points out that his argument isn't intended to prove God exists. Rather, it is intended to say that belief in God doesn't require evidence to be rational. Plantinga's challenge is to the evidentialist's claim that only those beliefs that have "sufficient evidence" can be rational. In a nutshell, the response is that the belief that that requirement is necessary is itself lacking sufficient evidence, so is self-refuting. It took Plantinga 500+ pages to get there, but that is, I think, the essence of his argument. But on its own, it isn't meant as an argument to demonstrate that God exists. Why should one accept irrational claims as evidences sufficient to justify a radical departure from ones ontological perspectives? Metaphysical naturalism is derived from scientifically established evidences that are rational. Why should one step off such a solid foundation into the ethereal goo of theism whose assertions subsist on claims that neither evidence nor rationality can be found among its ingredients? |

Of course, Kenny’s argument that it’s more reasonable to postulate an infinite “ultimate ground of being” than a finite one seems plausible. But this is quite a different thing from inferring God’s existence from evidence. What would evidence of an “ultimate ground of being” even look like? How could we know that any evidence whatever didn’t have a finite cause? Quote:

Kenny:
For technical reasons I’ve chosen to reply to your Jan. 31 posts in reverse order. Thus this post is a reply to the second one. 1. Rational justification and warrant. It’s easy to confuse the notions of rational justification and warrant. What Gettier showed was that it’s possible to have a true, rationally justified belief yet not have knowledge. And an analysis of his examples seems to show that our conception of “knowledge” seems to involve some kind of relationship between the reasons for the belief and the state of affairs that make that belief true; it’s the fact that such a relationship is absent that makes us say that the people in his examples don’t really “know” even though they have justified true beliefs (JTB’s). As you said some time ago, the concept of “warrant” is intended to bridge the gap between JTB and knowledge: Quote:
The difference between the two, of course, is supposed to lie in the additional requirement that (in the case of true beliefs at least) the reasons for the belief must have the “right” relationship to the reasons why it is true (i.e., the state of affairs that makes it true). But we have no way to tell (in general at any rate) whether this “right relationship” exists. It seems to me that having a justified true belief inherently involves having a justified belief that such a relationship exists, but that doesn’t insure that it does. (Any of the Gettier examples will illustrate this.) Thus, while it is of some philosophical interest to analyze exactly what relationship must hold between the reasons for a belief and the reason it is true in order for the belief to qualify as “knowledge”, it’s really of no practical interest, nor does it really have anything to do with rationality per se. At any rate, I had no intention of trying to solve the knotty problem of coming up with an adequate conception of “warrant”, or in other words of solving the Gettier problem. (Lots of better philosophers than I have tried to do this and failed.) In fact, I didn’t really try to define a concept of “warrant” at all. So it’s hardly surprising that my analysis is not “sufficient for a characterization of warrant”; I was never under the delusion that it was. In fact, I’d have no real quarrel with Plantinga’s criterion if the only problem with it were that it is an “insufficient characterization of warrant”. It’s true that I thought it worthwhile to point out that it fails utterly to identify anything that could be considered a plausible candidate for the “right relationship” needed to resolve the Gettier problem. But the main problem I have with it (in the context of a discussion of the rationality of theistic beliefs) is that it fails to meet even the minimal test of being a stronger concept than rational justification; that is, it’s possible for a belief to be “warranted” in Plantinga’s sense without being rationally justified. This is important, because Plantinga essentially argues that theistic belief is warranted (by showing that it meets his criterion of warrant) and then clearly wants us to draw the seemingly obvious conclusion that it is rationally justified. 2. My interpretation of “rationality” But before looking again at Plantinga’s criterion, I want to consider your critique of my concept of “rational justification” (which, unlike the concept of “warrant”, I really did try to characterize, at least in broad outline). You say that the justification I offer for being rational – i.e., for following the “rational strategy” - is essentially pragmatic. It’s not at all clear that this term is properly applicable here. For example, according to the Stanford Encyclopedia of Philosophy, “Pragmatism demands that philosophy grow out of and test its merits in the ‘soil’ of lived experience.” That’s certainly not true here: the strategy of rationality is world-independent – that is, its justification is that it is the best way to interpret or conceptualize our experiences (and predict future ones), and as such must be logically prior to all experience. In fact, strictly speaking, rationality doesn’t require belief in the principle of induction, etc.; it only requires that one act on certain principles. That is, it demands that one act on the premise that regularities observed in the past will extend into the future, that one’s memory is reliable, etc. But it is humanly impossible to act routinely on such premises without believing them to be true. So in the final analysis the only “pragmatic” part of the rational strategy is that we should not try vainly to resist our minds’ insistence on believing premises that we act on regularly, but should just go ahead and believe them. I think that this is what Gale was getting at in his interesting paper The Overall Argument of Alston's Perceiving God when he said (in a closely related context): Quote:
In other words, unlike all of your examples, accepting the reliability of one’s memory, applying the principle of induction, etc., are not optional. In fact, this sort of thing is the essence of rationality itself. A person who actually rejected the principle of induction, or refused to accept the reliability of his memory, or routinely failed to apply Ockham’s Razor, would not be a skeptic, but a madman; he would quickly be locked up in a loony bin. So, just what kind of justification can be given for following the “rational strategy”? A rational justification? That would be absurd: transparently circular. No, the only possible justification for being rational – indeed, the only possible justification for any recommendation or decision about “what to do” - is a “pragmatic” one, in the sense that it has to refer to the results it can reasonably be expected to have. So this criticism is no criticism at all. Accepting (e.g.) the principle of induction isn’t a bit like deciding to believe that you can jump a ravine to escape from a bear in order to increase the likelihood of escaping from the bear. In this case you’re adopting a particular belief for the express purpose of achieving a particular desired result, whereas the point of adopting the rational strategy is to be able to achieve any results at all; it’s not aimed at any specific result. You say that, while I’ve justified believing in such things, we still don’t know whether they’re true. Gale comments of this as well in the article I quoted from earlier: Quote:
This can be seen most clearly by considering the most fundamental question of all: “Am I sane?” (Or if you prefer, “Am I rational?”) Of course I think I am; in fact it seems self-evident to me that I am. But I can imagine being completely insane while being perfectly certain that I’m sane. How can I be sure that I’m not in such a state? The answer, of course, is that I can’t. The absurdity of a madman appealing to his fundamental intuitions is too obvious to need explaining. And if (following in Descartes' footsteps) I try to fashion an argument showing that I must necessarily be sane, how can I have any confidence in the validity of the argument without knowing in advance that I can distinguish a valid argument from an invalid one? But while my approach (like any other) leaves room for “philosophical doubt”, that doesn’t mean that it precludes the possibility of knowledge. Take the example of seeing someone that I take to be Susan in the mall. Am I rationally justified in believing that Susan is in the mall? Yes, obviously. There’s no point in objecting that I’m assuming that my memory is reliable (and that some complex cognitive functions are in good working order for that matter), and that I have no evidence for these things and no “reason” at all in the usual sense to believe them. These assumptions are part of rationality itself. Thus in saying that my belief is rationally justified, I’m saying that I am using these presuppositions (and no other ones) to arrive at my conclusion. That’s what it means to say that a conclusion is rationally justified. Moreover, if (unlike the original example) I really am seeing Susan, my belief is true. Finally, on any reasonable interpretation of “warrant”, my belief is warranted, since my reasons for believing it obviously have the right kind of relationship to the state of affairs that makes it true (namely Susan’s being in the mall). This is the type of paradigm case that serves as a test of a concept of “warrant” to see whether it’s reasonable. In other words, this is precisely the kind of case where we want to say that the belief has “warrant”, and therefore constitutes “knowledge”. Any concept of warrant that says that this belief is not warranted is immediately out of court on that account alone. Finally, you argue that my account of rationality is flawed because lots of beings who don’t follow the “rational strategy” clearly have rationally justified beliefs: Quote:
Quote:
Thus, although it’s true that, as you point out, my account is “neither necessary nor sufficient for an analysis of knowledge” (an analysis that I did not attempt) I see nothing in your comments that even tends to show that it is not a good account of “rational justification” – which is, after all, what we’re talking about in this thread. 3. Plantinga, warrant, and rational justification Now let’s turn to you discussion of my critique of Plantinga’s conception of “warrant” and its relationship to rational justification. First off, let’s look at what you have to say about the rationality of the beliefs of RN beings. Recall that I stipulated that they were Quote:
Quote:
Quote:
This brings us to my counterexample of the beings C(n), each of whom is designed to believe a certain proposition P(n) for reasons that have nothing to do with its truth. In the case of C(10,001) this proposition happens to be true. But it will also be true, by definition, in the “type of environment” in which P(10,001) is true. Moreover, it is a simple matter to stipulate that the method by which he is “programmed” carry out his intended function would only work if P(10,001) is true. That is, we can stipulate that his designers hit upon a plan that would work only if P(10,001) is true – which is to say, only in the “type of environment” in which it is true. (They didn’t care about this restriction because they knew that, as a matter of fact, it is true). Thus C(10,001)’s belief forming mechanisms are indeed part of a well designed plan aimed at the production of true beliefs in the type of environment in which he is designed to function. Quote:
Quote:
Quote:
Besides, this question is irrelevant if the worlds in which “the sort of beliefs the cognitive faculties in question were designed to produce” are largely false are worlds in which the being in question cannot function properly. Quote:
But more importantly, the term “external rationality” just doesn’t make sense; it’s an oxymoron. A person is rational if he responds to his experiences in a rational way. If he forms reasonable hypotheses about the external world; if he comes to reasonable conclusions to account for his experiences, he is being rational. That’s what it means to be “rational”. If he happens to be wrong through no fault of his own; if his experiences systematically mislead him about the nature of the external world (for example, because he’s in the Matrix), this doesn’t make him irrational in any meaningful sense. That’s the point of the concept of “warrant”. A belief is warranted only if the reasons for it have the right relationship to the state of affairs that makes it true. This is an external relationship. Rationality is an internal state. To say that someone is “rationally justified” is to say that he has acted appropriately in some sense; that he has a “right” to believe what he does based on what he knows. If two beings are presented with exactly the same experiences and arrive at the exact same beliefs in the same way, either both of them have rationally justified beliefs or neither of them do; if the cognitive processes of the one can be described as “rational”, the cognitive processes of the other can also be described as “rational”. Otherwise we are forced to say that whether a belief is rationally justified can depend not only on why the person has the belief but on whether it’s true. But the whole point of the concept of rational justification is to separate these questions; even if we don’t know whether a belief is true we can (often at least) determine whether it is rationally justified. But if rationality is inherently an internal or intrinsic property of a being, it cannot depend on what world the being happens to find himself in. In other words, it must be “world-independent”. Thus the problem with defining a belief as warranted “if and only if it is formed through the proper functioning of one’s cognitive faculties which are part of a well designed plan aimed at the production of true beliefs in the type of environment in which those cognitive faculties were designed to function...” is that this is not sufficient even to make a belief rationally justified, much less warranted. (And as I pointed out a while back, “warrant” is supposed to be a stronger condition than rational justification; “Belief X is warranted” must entail “Belief X is rationally justified”. If not the whole discussion of warrant is irrelevant to the current discussion anyway.). To be rationally justified, a belief must be the product of a belief forming mechanism “aimed” at the production of true beliefs, period. It may not succeed in all worlds, but it cannot be tailored to the particular world (or type of world) that the agent happens to be in. Otherwise we end up being forced to say of two beings who are presented with exactly the same experiences and arrive at the exact same beliefs in the same way, that one of them has rationally justified beliefs and the other doesn’t. I’d like to say more, especially about why beliefs that result from a “designed-in” predisposition to them can never be rationally justified, but I’m out of time for now, and this post is already long enough. Whew. This is taking a long time, and it’s making my head hurt. |

This is interesting- in the legal world, "warrant" basically means:
b: to serve as or give adequate reason or authorization for Example: {h,2}warranted the awarding of attorney's fees Example: was not {h,2}warranted by the facts (And of course, there are the "warranties" that are given as assurances that some state of affairs actually exist- warranty of title, warranty of ability to contract, warranty of merchantibility, etc.) If a judge is issuing a warrant, a police officer must swear that the facts presented are true. The warrant, then is actually a document that says, the facts as presented, IF TRUE, create probable cause. So at least in this world, the fact comes before the circumstances. The facts are established first, and then the combination of facts is analyzed to see whether they "warrant" the conclusion. However, you don't have to have the facts proven first. It's basically- the facts if proven, warrant this conclusion. The facts can be hypothetical. A belief is warranted only if the facts, if true, or if believed, justify the conclusion. So is the theist saying that the belief in God's existence is warranted because if we said certain things about the state of the world, the conclusion that God exists would be true? |

Thanks bd-from-kg,
I await the rest of your response. In the mean time, I tried your Gale link and it didn't work. Perhaps the site is temporarily down, but if the link is broken, could you please fix it? God Bless, Kenny |

Kenny:
The link worked fine for me last night and still works this morning. Anyone else having problems with it? ReasonableDoubt: The meaning of "warrant" in the theory of knowledge has very little to do with its everyday or "ordinary language" meaning. |
