The context to this discussion is in setting up an abductive argument for God such as the abductiver version of the Transcendental signifier argument. But it can work for any abductive approach to God argument.
According
to Lipton not all induction is probability. He draws the line between
deductive and inductive at the point where it is no longer impossible
for the premises to be true and the conclusions false; when that's
the case its deductive. Inductive is weighing probability not proof.[1] Inductive considerations arise out of indeterminism. It is because
outcomes are not necessitated t1hat we can have probability. In
assessing the nature of the best explanation, Lipton finds
that justification supports explanatory power because with
indeterminism we can only go by likelihood. If likelihood were the
only guide abduction reduces to induction, or a form of it. Rather he
finds that we can't construe best as likeliest alone, but we should
view abduction as a guide to inference, not as proof. He urges us to
see explanatory factors as guides to illuminating likelihood rather
than the other way around. [2] To use my own examples: suppose someone argues that its not likely
that the former friends are jogging together because they made up;
the former friends could be jogging together so that they can insult
each other. That doesn't seem believable because one hates conflict,
the other is too mature. Thus that is a less likely explanation than
the theory that they made up. How would likelihood work with the
question of God? How to establish probability of an issue such as the
reality of God, where there is an inability to produce empirical
proof? Such a discussion could not help but be dominated by prior
convictions. Yet if we value explanation and we have reasonable
parameters for what needs explaining the explanatory power might give
a clue to likelihood. This means we are still left with how to
establish “best.”
Gabby
and Woods offer a rule to determine explanatory power. The rule sets
up a criterion of comparison between hypothesis. At least one element
must be more plausible in given hypothesis than its counter parts in
competing hypotheses.
[3] They develop much more complex statistical theorems. The problem is,
even though setting up criteria of comparison is a god idea, we still
can't just assert the likelihood of God, or even the unlikelihhod.
The individual must decide the values by which to set parameters for
comparison. For example if we value explanations that assume a “why”
to the universe then God as explanation seems more likely. If we
assume flat out there can be no why then we have already eliminated
God from consideration. The problem in making a God argument is that
God is not given in sense data. Thus God can't be the subject of
empirical investigation. What we can do is to specify parameters and
criteria that prepare us to make educated decisions about belief. In
other words, we can't draw a picture of the hole in a doughnut, but
we can draw the doughnut around the hole. In the case of God that
means rational warrant justifies belief. Rational warrant means that
a given belief is possible and plausible, thus not irrational.
We
might be able to say that the best explanation would account for all
the data or account for the most crucial data than other
explanations. We could also stipulate that the explanation be the
most simple as long as we don't confuse conceptual simplicity with
absence of data, or simplicity of structure. For example when Dawkins
argues that God would have to be more complex than the universe he
creates, he's assuming the laws of physics apply to God.[4]
He's ignoring conceptual simplicity. Most of the great apologists
such as Aquinas saw God as conceptually simple.[5]
In other words God is not made up of physical parts. This raises the
issue of Occam's razor and parsimony. Parsimony is a principle akin
to abductive reasoning used in science where direct empirical data is
lacking. It was based upon Occam's razor but the two are not
identical. Atheists have, on occasion, taken Occam's razor as a means
of ruling God out of the equation. They either assert that God is not
necessary, thus Occam's dictum about not multiplying beyond necessity
applies to God, or they think Occam said take the simplest of two
hypotheses.[6]
They
are also confusing Occam's razor with Parsimony. Occam was a priest
and he believed in God he didn't think the razor got rid of God.
Moreover, what the razor really says is that we should not multiply
entities beyond necessity. [7] Atheists
assume that since they don't believe in God then God is not
necessary. This is begging the question. They are asserting the lack
of a God and using that position to deny the God argument.
To
understand what Occam was really talking about we must understand his
nominalism.
three senses of nominalism:
(1) Denial of metaphysical universals: applies to Occam.
(2) reduce one's ontology to bare minimum, streamline categories: applies to Occam.
(3) Nix abstract entities, depending upon what one means; here Occam may or may not have been a nominalist in this sense. he did not believe in mathematical entities but he did believe in abstraction such as whiteness, or humanity.
Ockham removes all need for entities in seven of the ten traditional Aristotelian categories; all that remain are entities in the categories of substance and quality, and a few entities in the category of relation, which Ockham thinks are required for theological reasons pertaining to the Trinity, the Incarnation and the Eucharist, even though our natural cognitive powers would see no reason for them at all. As is to be expected, the ultimate success of Ockham's program is a matter of considerable dispute. [8]He was not getting rid of God. Occam's razor never allows us to deny what Spade calls "putative entities" which would definitely include God. [9] It merely bids us refrain from positing them without good reason. Of course our atheist friends would tell us there is no good reason to assert God, but answering that is the point of making God arguments. In fact for Occam humans can't really know what is necessary. "For Ockham, the only truly necessary entity is God; everything else, the whole of creation, is radically contingent through and through. In short, Ockham does not accept the Principle of Sufficient Reason.[10]This is not a contradiction because all the razor says is refrain form multiplying entities without good reason, not “rub out of existence all concepts that can't be empirically verified.” Note that he includes God as the only truly necessary entity. Thus atheist are violating Occam's razor in trying to use it on God. Of course there is equivocation in the of the term “necessary.” Atheists making the argument applying the razor to God speak of causal necessity while believers rest their ontological arguments upon ontological necessity.
An example of how “best explanation” should be considered:
This example is based upon the multiverse argument. The idea of the multiverse is taken seriously in science, even though it is the stuff of comic books and science fiction. The notion is what it sounds like: reality is divided into an infinite array of parallel universes. The argument is used to answer the fine tuning argument for God. The fine tuning argument says that the attributes of the universe that make life possible are so unlikely the game must be fixed. That's a good reason to believe in a planing intelligence as a creator. Our atheist friends say “not so fast.” There are infinite universes, thus infinite chances for life bearing. With infinite chances the odds of hitting life bearing are not so remote so there is not such a good reason to assert the need of a God. There are good answers to this, the argument is defensible. I wont defend it here because its not relevant. I am not asserting fine tuning to save the TS. My purpose in raising it is to make a point about how to consider best explanation.
The multiverse argument illustrates how the assumptions we make change the kind of explanation we seek. Is the multiverse necessary? It's a matter of empirical investigation and there may be empirical evidence to support it. Claims have been made of hard data proving Multivese, but when investigated they evaporate. Here's a physicist who opposed string theory and multiverse. He argues that his evaluation of the papers finds irresolvable problems.
In recent years there have been many claims made for “evidence” of a multiverse, supposedly found in the CMB data... Such claims often came with the remark that the Planck CMB data would convincingly decide the matter. When the Planck data was released two months ago, I looked through the press coverage and through the Planck papers for any sign of news about what the new data said about these multiverse evidence claims. There was very little there; possibly the Planck scientists found these claims to be so outlandish that it wasn’t worth the time to look into what the new data had to say about them. One exception was this paper, where Planck looked for evidence of “dark flow.” [11]
If hard evidence turns up for it then we have to deal with that on it's own terms. Until that time Multiverse should be shaved with Occam's razor. We don't need it to explain reality, it's only advanced to keep from having to turn to God. It's naturalistic so it's an arbitrary necessity at best. Arbitrary necessitates are logical impossibilities, contingent things jumped up to the level of necessity to answer a God argument. It's not that we are going to disprove the unnecessary entity (multiverse) but we are going to refrain from advancing it's existence as an assumption until such a time that real evidence makes it empirically undeniable. We can make that kind of ruling about the multiverse because its an empirical matter, even though it may be undetectable; God is not an empirical matter because God is both transcendent and transcendental. Therefore, Multiverse should be taken out of the issues of God arguments, yet we can't make that ruling about God. That's an example of what I meant when I said we can fill in the doughnut around the hole. If we find empirical evidence of multiverse we may have to re-think a couple of God arguments, In the mean time God might be the best explanation for the uniqueness of our world.
In any case parsimony is perhaps the best point of inference for abduction.
Most philosophers believe that, other things being equal, simpler theories are better. But what exactly does theoretical simplicity amount to? Syntactic simplicity, or elegance, measures the number and conciseness of the theory's basic principles. Ontological simplicity, or parsimony, measures the number of kinds of entities postulated by the theory. One issue concerns how these two forms of simplicity relate to one another. There is also an issue concerning the justification of principles, such as Occam's Razor, which favor simple theories. The history of philosophy has seen many approaches to defending Occam's Razor, from the theological justifications of the Early Modern period, to contemporary justifications employing results from probability theory and statistic[12]
Again
we have to distinguish between conceptual simplicity as opposed to
mere ignorance of the case, or simple structure. In other words
Dawkins treats God as a big man who must have more parts than the
universe he creates (see above). That is simplicity in terms of
structure, the physical structure of God. That is a case we just
don't know about. We can't judge that. We can think of God as the
simpler concept in terms of the economy of relations. First we can
think of God as mind, not brain. We do not know that minds are
complex. Brains are complex but we know nothing about mind. On the
other hand we might posit that mind is simpler than brain because
it's not a set of biological parts, but at least theoretically might
be akin to the spirit. In any case God's relation to the whole is
simple: one mind which thinks the universe. One mind that in the act
of perceiving sets all meaning, creates all that is, and judges all
moral value. That is more simple in terms of economical relations
between all parts than a multiverse. A multiverse would multiply the
problems of fine tuning and something from nothing by every universe.
To
spell out the criteria by which we might judge a “best”
explanation, not just simplicity alone but conceptual simplicity, we
must be able to make comparisons between hypotheses. We can't compare
hypotheses if they don't compete for the same results. Belief in God
is not a scientific hypothesis, thus it does not compete with
science. Thus belief cannot be reduced to the simplicity of “the
best science.” For this reason we can call the kind of parsimony of
the abductive version as parsimony of elegance. In other words
not just take the simplest idea, but take the truly elegant
hypothesis. By “elegant” is included conceptually simple in terms
of relation to the whole theory, as well as consistant, competitive,
and complete (accounts for most data, and most crucial data). To make
a list of qualities of an elegant hypothesis. Above I quote Baker as
saying elegance is number and conciseness of the theories basic
principles. Ontological simplicity is the number of kinds of
entities. By that measure God would be both eligant and ontologically
simple: one kind and its concise. To that I add the notion of bang
for the buck; not just fewer kinds and more concise but accomplishes
more for less.

What is known as Occam's razor was a common principle in medieval philosophy and was not originated by William, but because of his frequent usage of the principle, his name has become indelibly attached to it. It is unlikely that William would appreciate what some of us have done in his name. For example, atheists often apply Occam's razor in arguing against the existence of a god on the grounds that any god is an unnecessary hypothesis. We can explain everything without assuming the extra metaphysical baggage of a divine being.

here's the criteria:
ReplyDeleteCriteria for choosing the best explanation:
I. Simple (elegant and ontologically simple).
Focus is on God's relationship to all aspects of the universe and reality. It's not about issues like what is God made of or does he have parts. The relation itself of the God concept to the universe is what is at issue. One concept that props up every thing is simpler than trying to account for everything through loose ends. That's why they want a grand unified theory. More concise and bang for the buck.
II. Competitive:
Does the explanation compete with other explanations? In a sense no, the other explanations are not scientific. Science and religion have different domains they are meant to do different things. God and science don't compete. Yet the question is not one of science vs. God but of world views. While science makes up a large part of the world view of scientists and skeptics (and believers too at times) if we think of atheism as a world view there's more to it than just science. Atheism consists of actively cutting out the kinds of existential and phenomenological explanations that are part of the believer's world view. So belief in God answers the questions abou8t life at a more philosophical level, to my way of thinking a more profound level. Science tells us how the physical world works. God tells us why there is a physical world. Of course there are limits to how much we are told. That's the job of Theological to figure out what God tells us and what God does not tell us. Belief in God competes with other philosophical level questions.
Religions are often thought of as competing with each other for believers, even though they all point to the TSED as a generic object of faith. This is not to say they are all the same or that it doesn't matter,
but for the sake of the TS argument I'm going to bracket that for now. Atheism and belief in God Compete directly because the farmer seeks to explain the world by removing the explanation of the latter. While most atheists turn to science for explanatory power they often embrace an ideological version of science that is tuned to screen out religious explanations.i God transcends our understanding and our observations. Thus God belief can't compete with science's answers of how the universe works; nor does it need to. It does answer the why, the best atheism can do is to assert that there is no why. To the extent that both world views seek to account foe ultimate origins.
So the issue is not one of science vs. belief in God, but belief vs. atheism. In other words given equal embrace of science which world view best explains the world? Some will claim that science rules out God because there's no necessary place for God in a world of modern science. That just depends upon what kind of explanation we seek. The believer must not allow the skeptic to pull a bait-and-switch whereby the workings of the physical world are put over as the best explanation just because they are the most certain.
III. Logically consistent with self and world:
ReplyDeleteNo internal contradictions in theory, and if it does contradict what we think we know it has to re-explain it in a way so as to account for the apparent contradiction.
IV. Complete:
Explains more of the data than other hypotheses, and coordinates the answer to all other areas or more other areas than do other hypotheses. Example. God not only explains something from nothing but also accounts for ethics and meaning. The totality of data is all aspects of existence. It can't be limited to just empirical data but all aspects of human being and the nature of existing.
In order to cover all data the answer must include the philosophical in that it considers the phenomena on a higher level than just the physical workings of the universe. We have to be careful, however, not to set up the criteria in such a way that God is the only valid answer because nothing else applies. God must be the best explanation because other alternatives are eliminated. To demonstrate that I have not just set things up to favor my argument, I will, when the time comes to eliminate other alternatives, show alternatives that also fit the criteria.
Why a philosophical answer? Why not just content ourselves with the physical universe and how it works? That approach would rule God out before one got started thinking about that question. By Metaphysical I mean in the sense Wiltshire uses it, talk about talk about the world (glossery). Or to put it another way, thinking about how to think about the world. That answer must proceed from a transcendental perspective, analyzing the system of thought itself. The answer must be on a transcendental or metaphysical level but need not involve God. Must we manufacture a reason for things? No but there is a fine line. The answer can't content itself with pure physics and no more, but it can't demand a purposive reason as the only option. The explanation (sans God) on the metaphysical level might involve just dealing with the consequences of a purposeless world. We have to face the possibility that there is no purpose, but by the same token the skeptic must respect a subjective sense as the justification for seeking purpose. It's true that this criterion asks one to acept positions that perhaps can't be proven, but we don't have to prove the actual reality of God to produce a rational warrant for belief. Even a subjective sense can be analyzed and subjected to forms of verification see my first book, The Trace of God: A Rational Warrant for Belief, available on Amazon).
These five qualities taken together are what I call “the best explanation.” The conclusion of the argument posits a TSED which can logically be understood as a generic God Concept. That conclusion has to meet the criteria. I will defend the premises as true statement based upon best educated judgement then show how the proposed conclusion meets the criteria as best explanation for the phenomena sited.
I think additional desiderata of a good explanation are prediction and integration with other (especially related) models. What does the model predict, especially for novel situations? What does the model allow you to do? Do the components of the model overlap with those of other models, or does the model contain elements found only within it and relevant only to a domain-specific explanandum?
ReplyDeletegood points. I'm not quite sure what belief in god would predict other than God's existence. Or other things the vrificatio0n of which would not require death.
