Marg,
In historiography, ad hocs are “suppositions about the past which are not already implied to some extent by existing beliefs” (McCullagh
http://en.wikipedia.org/wiki/Historical_method). That is, suppositions that have no evidentiary basis. They are quite rational, although they are unfalsifiable. Historical interpretations with fewer ad hocs are given preference.
To start off, where Dan does McCullagh ever say that one should choose as best explanation , “Historical interpretations with fewer ad hocs are given preference.”? He doesn't.
From the link to Wiki that I provided, Christopher Behan McCullagh’s discussion is summarized under “seven conditions for a successful argument to the best explanation”. Point five reads:
5.The hypothesis must be less ad hoc than any other incompatible hypothesis about the same subject; that is, it must include fewer new suppositions about the past which are not already implied to some extent by existing beliefs.
These same points are given on p. 19 of his book. In the quote you give, McCullagh recognizes some exceptions to the rule when it comes to theories that have great scope and explanatory power, which doesn’t apply to the Spalding theory (or to your use of ad hocs to save it from adverse evidence). Smith alone theory has far more scope and explanatory power than the Spalding theory—which originally had the appeal of explaining how an ignorant farm boy could produce the Book of Mormon. This explanation has become unnecessary in light of what we now know about Joseph Smith and the Book of Mormon. The Spalding theory has no scope and explains nothing. This deals with McCullagh’s second point:
2.The hypothesis must be of greater explanatory scope than any other incompatible hypothesis about the same subject; that is, it must imply a greater variety of observation statements.
However, are you quoting this to show that your ad hocs do not mean the Spalding theory is false or just to say I don’t know what I’m talking about? If the former, I would be happy that you recognize that you have been inventing ad hoc defenses against adverse evidence. Nothing could be clearer. If the latter, I think you do not understand McCullagh’s discussion. But I think our concern is less with exceptions and what ad hocs prove or don’t prove and more with acknowledging that you have been using ad hocs as a major crutch in your debating style—which leads to a huge waste of time and band width trying to keep the discussion on more meaningful and fruitful paths.
Couple of things to note. Your say so, and opinion that many of the explanations of the S/R theory are ad hoc is simply that ..your opinion..they are not ad hoc. For example, the evidence indicates another manuscript existed besides the Manuscript Story Conneaut Creek. Your accusation that the hypothesis of another existing is "ad hoc" fallacious ..is nonsense. You have been using your own distorted fallacious reasoning throughout this entire thread.
This is no different than what you have already fallaciously asserted in the past. Here you pick what you think is the weakest example of what has been labeled ad hoc, when there have been several—some of your own invention.
Trick hat--to escape eyewitness testimony
Conspiracy of witnesses to lie-- to escape eyewitness testimony
Book of Mormon was originally about ten tribes—to escape implication that Spalding witnesses’ memories are unreliable
Passages in Book of Mormon about ten tribes in north added by Joseph Smith or SR—to escape implication that Spalding witnesses’ memories are unreliable
“lost tribes” can mean one tribe—to escape implication that Spalding witnesses’ memories are unreliable
Long scenario about Spalding having Lehi come from lost tribes and rejecting contemporary theory of lost tribes and Indian origins—to escape implication that Spalding witnesses’ memories are unreliable
Hurlbut sold the second MS to the Mormons—to save the thesis of a second MS from an obvious problem
Sidney Rigdon pretended to be converted to Mormonism in November 1830—to explain away SR’s denials
Parley P. Pratt only pretended to bring the Mormon gospel to Joseph Smith—to explain away corroboration of SR’s denial
Ad hoc is when counter evidence against a hypothesis, not mere opinion (such as your say so) refutes a hypothesis and then to rescue that hypothesis from the counter evidence an explanation (ad hoc)is thought up but is unjustified other than its purpose is to rescue the hypothesis.
Again, this is nothing new. You said this before, and you’re still wrong. As you can see in my quick summary, your ad hocs were invented to respond to adverse evidence—not simply my say so. Besides, in history ad hocs are also missing pieces of the story—“ suppositions about the past which are not already implied to some extent by existing beliefs”—not necessarily responses to adverse evidence. However, as you can see from my list, it’s quite clear that you tried to invent and speculate your way out of adverse evidence. We tried to tell you that you could not do that, but you would have nothing to do with it. I hope now you understand that you can’t do that without being called on it. Here is the part of McCullagh’s discussion you left out:
It can be seen that these three ways of neutralizing the effect of apparently disconfirming evidence have much in common. Each involves creating an explanation of the evidence which is compatible with the hypothesis being defended. It looks as though, with sufficient ingenuity, almost any hypothesis could be rendered immune from disconfirmation this way. … When are such saving hypotheses, as we might call them, acceptable? And at what point is it reasonable for an historian to abandon a hypothesis in the face of apparently disconfirming evidence, rather than continue to protect it? … [p. 31]
The ability of historians to defend their hypotheses by creating ad hoc explanations of evidence which appears to disconfirm them, is limited by the need to make those ad hoc hypotheses more acceptable, according to the recognized criteria, than the other interpretations given to the evidence. If this cannot be done, then historians are forced to admit that what had seemed to be a true hypothesis must be false. … [p. 32]
As I pointed out months ago, ad hocs don’t automatically disprove a theory, but the more a theory relies on them the less likely it is to be true and it become increasingly irrational to hold onto such a theory. Remember, I quoted Theodore Schick, Jr., and Lewis Vaughn,
How to Think About Weird Things: Critical Thinking for a New Age (Mountain View, CA: Mayfield Pub. Co., 1999), 156-58, in this regard—“ When a scientific theory starts relying on ad hoc hypotheses to be saved from adverse data, it becomes unreasonable to maintain belief in that theory. …” However, none of the ad hocs you offered are more plausible or probable than what you were trying to overcome. Needless to say, none of them have greater scope and explanatory power either. This is why the Spalding theory has been abandoned—it explains nothing and creates a mess that needs continual ad hoc support. But, for now, I’ll settle for the recognition that you have been creating ad hoc responses to adverse evidence—which you seem to want to still resist.
Your say so that another manuscript didn’t exist…is not counter evidence. Your Book of Mormon witnesses are not reliable witnesses despite your reliance on apologist Anderson's say so. So let’s get that straight …
The burden is on you to prove another MS existed—one of the major problems with that theory is what Hurlbut did with it. Eyewitness testimony to the translation doesn’t rely on Anderson’s say so, but you’ll have to read the book to find out his evidence. I quoted an affidavit signed by many people who knew David Whitmer to counter your unsupported assertion that he was a liar—to which you gave no intelligible response. Your use of conspiracy theory to explain away eyewitness testimony is ad hoc because it has no evidence supporting it. You draw on it because you need to neutralize counter evidence. At the time, it seemed the only alternative to your hat trick theory.
you don’t even know what “ad hoc” is...or you do but deliberately are misusing it.
It’s use who doesn’t know what one is, which leads you into this error over and over.
You also didn’t know what Occam’s Razor was in past discussions because you didn’t appreciate that it was between hypotheses with equal explanatory power. This is a key concept you fail to acknowledge. You seem to not appreciate how explanatory power fits in and is necessary both for Occam’s Razor and for arguments to best explanation by McCullagh.
From the start, I told you I wasn’t using Occam’s Razor in the narrow sense, but in the way it is generally used. You keep bringing this up like you made some important point. I also told you I didn’t need to use the term since the concept of preferring theories that are less ad hoc is quite clear in historiography. MCCullagh doesn’t use the term, but is quite clear that ad hocness is an issue that historians are concerned about—“ The hypothesis must be less ad hoc than any other incompatible hypothesis about the same subject.”
Although I have criticism of McCullagh explanations, I’ll leave that because it’s not essential for our discussion.
Funny, I don’t find it necessary to criticize McCullagh. I can’t tell you how arrogant your statement sounds.
I find your analogy between McCullagh’s examples and the Book of Mormon/Spalding debate uninteresting and distracting from the main subject here—and that is your use of ad hoc escapes. However, the most important thing to note is how the scholar favoring the conspiracy theory didn’t believe he could make a convincing argument because of the ad hoc nature of his theory.
Explains
- Rigdon’s extraordinary immediate conversion and and quick rise to power
- just as the church explains how unlikely it was that Smith could or even would have written the Book of Mormon …a better explanation it that it involved input from different people, more knowledgable, more interested in writing such a book and more capable at the time than Smith
- the many and varied witnesses who recall a spalding manuscript which matches closely to historical parts in the Book of Mormon..credible witnesses with no motivation or benefit to lie
-why only small knit group essentially family were involved as witnesses during the writing process
-why a blanket was used to conceal smith from public view
(I could go on, but Roger or Dale would be much better in all describing all the things from evidence the S/R theory explains. It is the theory which has greatest explanatory power and therefore argument with best explanation.)
The Spalding theory explains nothing. Rigdon’s conversion was no more sudden than anyone else’s. His conversion (as also many others’) was due to their preparation in restoration doctrine. This was dealt with in my book
Religious Seekers and the Advent of Mormonism Mikwut also discussed this in detail. This information has greater explanatory power than the Spalding theory, which only attempts to explain Rigdon’s conversion.
The Spalding theory only has the potential to explain the production of the Book of Mormon, but it can’t explain Joseph Smith’s dictation of the Book of Moses, Book of Abraham, his many revelations, and his many sermons, given impromptu and captured by scribes. Joseph Smith liked to play up his lack of learning as evidence for his inspiration—but evidence supports the conclusion that he wasn’t as ignorant as he pretended and the Book of Mormon isn’t as literary as apologists claim. In fact, there are many aspects about the Book of Mormon that neither Spalding nor Rigdon could be responsible for.
The Spalding witnesses have nothing to do with the power and scope of the theory. In fact, their claims rely on a rather spectacular feat of memory. The lack of motivation is an assumption; they were voluntarily supplying information to Hurlbut in an attempt to destroy Mormonism. Regardless, this is not evidence of explanatory power.
The Spalding theory doesn’t explain why only a small group witnessed Joseph Smith dictating the Book of Mormon—it only claims similarity between two books. The rest is one ad hoc theory after another to explain how it happened.
The Spalding theory doesn’t explain why Joseph Smith used a blanket so that people coming to the Whitmer door couldn’t disturb his dictation.
Note, the 3rd theory, the conspiracy that King William was murdered has the most suppositions and according to your reasoning Dan it should be rejected and the simplest theory that the King was accidentally killed should be accepted as the best explanation. Fortunately though both Brooke and McCullagh are better critical thinkers than yourself. Thank goodness for that.
You are missing the point, Marg. McCullagh examines the three using the seven criteria, not just one, and he is using ad hoc for both supposition and explanation of counter evidence—meaning it has the least evidence but the greatest explanatory power. So under
ad hocness, he states
(5) Ad hocness As none of the hypotheses is clearly rendered probable by the total available evidence, all must be regarded as ad hoc, specially created to account for reports of King William’s death. It is tempting to say that the second hypothesis is more ad hoc than the others because it is so implausible, and the third hypothesis is less ad hoc than the others because of its much greater explanatory scope. But that would be to confuse ad hocness with other characteristics of the hypothesis.
The first theory was also disconfirmed by Tirel’s denial of accidentally shooting the King, which Brooke explains as evidence for conspiracy in assassination. Not strong, but a defender of the first theory might claim Tirel denied it out of embarrassment. After all, who would want to go hunting with him for fear of being accidentally shot? Or the two histories were reporting rumor and Tirel didn’t shoot the kind, but it was some other unidentified person, who did it by accident. In this way, ad hocs would be multiplied in order to hold onto the theory and we would have a situation like the Spalding theory.
Theory 3, the conspiracy theory that the King was murdered, the one with the most suppositions is the one preferred by Oxford historian Brooke and although it is acknowledged as not being proven it is the one which best explains the evidence. McCullagh does not call those explanations for # 3 ad hoc, nor does he say it should be rejected on that basis. The simplist theory # 1 that the King was accidentally killed and the most straightforward most widely believed and accepted ..si not the one chosen as the theory to best explanation. # 1, doesn’t explain the evidence as well as # 3. McCullagh while acknowledging # 3 is not proven, argues it is the best explanation.
McCullagh is giving an example of how ad hoc in the form of filling gaps is less important than explanatory power. The same can’t be said for ad hoc defenses against adverse evidence. Note that Brooke took what looked like adverse evidence—Tirel’s denial—and made it supportive of his position. He actually increased the explanatory power of his thesis, which ad hoc escapes don’t do. They only exist to keep the main theory alive.
On this basis Dan, the reasoning in McCullagh’s book (he’s a philosopher of history not a historian) favors the S/R theory not the Smith Alone.
You are making only a superficial comparison by linking one conspiracy theory to another. First, we have a lot more evidence to consider than Brooke had with his subject. Second, the conspiracy McCullagh describes has explanatory power and some evidence supporting it, but the Spalding conspiracy theory has no evidence and explains nothing--but creates more problems than it attempts to answer. Moreover, the Spalding theory relies on twenty-year-old memories of non-independent witnesses about the contents of a MS, which is contradicted by more reliable independent testimony as well as many other known facts, which can only be overcome by ad hoc speculations. Look at McCullagh’s other criteria:
2.The hypothesis must be of greater explanatory scope than any other incompatible hypothesis about the same subject; that is, it must imply a greater variety of observation statements.
Smith alone is superior.
3.The hypothesis must be of greater explanatory power than any other incompatible hypothesis about the same subject; that is, it must make the observation statements it implies more probable than any other.
Smith alone is superior.
4.The hypothesis must be more plausible than any other incompatible hypothesis about the same subject; that is, it must be implied to some degree by a greater variety of accepted truths than any other, and be implied more strongly than any other; and its probable negation must be implied by fewer beliefs, and implied less strongly than any other.
Smith alone is superior.
5.The hypothesis must be less ad hoc than any other incompatible hypothesis about the same subject; that is, it must include fewer new suppositions about the past which are not already implied to some extent by existing beliefs.
Smith alone is superior.
6.It must be disconfirmed by fewer accepted beliefs than any other incompatible hypothesis about the same subject; that is, when conjoined with accepted truths it must imply fewer observation statements and other statements which are believed to be false.
Smith alone is superior.
7.It must exceed other incompatible hypotheses about the same subject by so much, in characteristics 2 to 6, that there is little chance of an incompatible hypothesis, after further investigation, soon exceeding it in these respects.
