Alright Honor,
I’ll try to be clearer this time around. I’d like to thank mfbukowski for re-posting his views again, it’s made writing this a much easier process. I’ll start from the beginning and try to give people some context to the discussion as I’ve seen it. A comment was made by mfbukowski early on this thread and I want to reproduce it:
mfbukowski wrote:My view can be called "Pragmatism". If you want to criticize my view- THAT is what to criticize! Look it up if you want- check out the counter arguments and when you are ready, let's talk.
The final court of appeals when it comes to mfbukowski is mfbukowski himself, so if his views are inaccurately represented, I’ll bear the sole responsibility for those errors. In an effort to reduce error, I’m going to quote heavily from mfbukowski. All statements attributed to him have been made in this thread and this thread alone.
I’ll start first by explaining induction and the two relevant issues that stem from inductive inferences, then I’ll reconstruct mfbukowski’s beliefs from his own words, and finally I will explain my criticism.
PART 1
At the heart of the matter lies the method of “Induction”. Induction is a method of inference that is used by modern science, to draw conclusions from observations about the unobserved (typically, the future). Unlike deduction (think math and logic), induction leads us to conclusions which are not entailed by the premises: conclusions which might be false, when the premises are true. There are two important questions about induction that separate mfbukowski and myself.
First, inductive inference does not merely pass from the observed to the unobserved: it does so, as a rule, by postulating a law. From a general law, I can then deduce conclusions from that law. The general law does have a bad short coming, it has to cover indefinitely many instances, so evidence from induction will always fall far short. What kind of validity could such reasoning aspire to?
Second is a question about the quality of evidence and this will lead us into “confirmation theory”. Trying to articulate general principles about determining the quality of evidence is actually a tricky business. It seems here that mfbukowski grasps this issue as well:
mfbukowski wrote:Is that at the present state of scientific knowledge? What qualifies as "evidence"? There is a thread right now on MADB offering reams of "evidence" for Book of Mormon- does that qualify as evidence for you?
PART 2
We need to focus on induction because mfbukowski comes from a school of Philosophy called “Pragmatism” that depends almost entirely on empirical evidence (or data gained from human senses) as the source of human knowledge. According to this school, we should study induction in terms of it’s utility. He expresses the idea well here:
mfbukowski wrote:What science does, in a very detailed way, chronicle human experience about the world so that anyone anywhere can do the same thing and get the same results. And the fact that it is so reliable means that anyone anywhere can USE that information- "knowledge"- to DO THINGS. In other words- science "works" to allow us to build buildings and make medicine and fly to the moon and make the atom bomb.
Ultimately what makes any proposition in science "true" is that it always "works". Combining Na to Cl will give you NaCl every time you want to make some NaCl. Doing this and this and this will give you an atom bomb every time. If you want to harden steel, you do this and this.
Science gives us knowledge which I would call "objective" because once we have the recipe, anyone anywhere can make the cake.
This is often called “verification” in other jargon terms. The more something “works” the more it verified, and at some point, it works so often that it becomes “Truth.” A lot of this is unobjectionable, but mfbukowski doesn’t stop there. Consider this comment:
mfbukowski wrote:So you take a proposition like "Nephites existed" and see what value- what importance- what a difference that proposition makes in the world.
One would look at how such a statement would be verified.
To most archaeologists in the world- frankly if probably has little if any significance as of today.
Yet millions of people believe that, and it has great significance in their lives, and for them it is "true" because that belief has made a difference in their lives. Believing that has practical consequences in their lives.
It’s important to understand that mfbukowski draws a sharp distinction that we must observe if we are going to examine his Pragmatism. While above, he mentions the utility of religious beliefs having positive impact on people’s lives, we should also keep this comment in mind:
mfbukowski wrote:But notice there is a BIG DIFFERENCE between an alleged "scientific truth" as presented by FC and a religious belief, and how one views the "truth" of either claim. Religious "truths" are verifiable only through subjective experience, while scientific "truths" are objectively verifiable through experiments which can be replicated.
We shouldn’t hold “religious truths” to the same verification standards as we do the natural sciences. One is objective and the other is subjective.
The boldest claim that mfbukowski makes has to do with the sovereignty that empiricism holds in his worldview:
mfbukowski wrote:I would say that something "real" is something for which I have experiential evidence.
That which is "real" is verifiable by experience, either subjectively or objectively. I would say that I have had (subjective) experiences which have verified (for me) the expression "God is real", but I have had no experiences verifying that Santa is real.
And
mfbukowski wrote:Independent of my experience and language usage, we have nothing.
What this means is that experience is king when it comes to obtaining knowledge, and the only way we can reason from this body of knowledge is to make use of induction. So let’s recap:
1: Almost all knowledge comes from experience.
2: Our collective and personal experiences are what we use to judge the utility of an idea.
3: A scientific or religious idea gains more utility every time “it works” to a person(s) benefit
4: The only effective way to reason from all this knowledge is by the method of induction.
PART 3
Induction works off this main principle:
P1: A generalization is confirmed by any of it’s instances.
And since mfbukowski has acknowledged a priori in language use, we can also affirm this:
P2: If two hypotheses can be known a priori to be equivalent, then any data that confirms one confirms the other.
What I contend is that P1 and P2 force induction into something that is counterintuitive and useless. Let’s take this statement for example:
R1: All ravens are black.
Now R1 is logically a equivalent to this:
R2: Everything non-black is non-raven.
As P2 states, anything that supports R1 a priori supports R2, and anything that supports R2 also supports R1. What this does is set us up for some absurd conclusions. Let’s suppose that mfbukowski and I are rival scientists and mfbukowski asserts R1, and I assert this:
M1: All ravens are magenta
M2: Everything non-magenta is non-raven.
Lets say that mfbukowski and I happen to be pragmatists as well, so we decide to head to the local park and put our assertions to the test, to find out “What works for us.” We spend all day at the park cataloguing every thing we see, but unfortunately, we found no ravens. At the end of the day, I declare that my assertion (M1) gathered far more evidence than mfbukowski’s (R1) and that my idea clearly works better.
Of course, that conclusion is absurd and would be rejected by everybody, but if you accept P1 and P2, you are forced to accept that conclusion. Every non-black thing that is a non-raven (R2) is affirmed for every tree we see, blade of grass, etc, etc. If R2 is affirmed, so must R1. Same thing goes for M1, and given that the color black occurs in nature and in human artifacts far more often than the color magenta, it’s safe to assume that we found more non-magenta non-ravens in the park than non-black non-ravens. Even though we didn’t see raven number one, we logically found more evidence for M1 over R1. The problems don’t stop there, and begin to compound.
Let’s say mfbukowski and I are joined by Runtu and we spend the next month combing public parks looking for ravens and cataloguing every thing we find. At the end of the month, we’ve discovered 65 individual ravens who were black and mfbukowski celebrates! M1 has clearly been disconfirmed and R1 stands vindicated, but Runtu interrupts mfbukowski’s celebrations by showing him his hypothesis, which states that the majority of Ravens are in fact purple, but the first 150 ravens we’ll find will be black. This puts mfbukowski’s celebrations to an early end because Runtu’s prediction is far stronger and easily more confirmed than R1, even if we know it is wildly absurd.
My examples are very basic and simplified to get my point across, but I’m fairly confident that any inductive situation that mfbukowski can conceive, there is a counter example that is much stronger, even if it is more absurd.
mfbukowski wrote:I haven't seen much evidence that you understand my "world view" in the first place, and secondly, the Hempel proof has little to do the central attitude of Pragmatism.
But go ahead- let's see how it goes if you like.
Just to recap mfbukowski’s views as derived from his comments on this thread:
1: Almost all knowledge comes from experience.
2: Our collective and personal experiences are what we use to judge the utility of an idea.
3: A scientific or religious idea gains more utility every time “it works” to a person(s) benefit
4: The only effective way to reason from all this knowledge is by the method of induction.
He has the follow options:
A: He can reject P1, which leave’s his worldview crippled with no ability to draw good inferences.
B: He can reject P2, which would discount most if not all forms of logic and cripple his ability to draw good inferences.
C: Accept the problem as is and cripple his ability to draw any inferences what so ever.
D: Solve Hempel’s problem without appealing to anything outside his strict empiricism.
I feel that A-C is unacceptable for mfbukowski and his only recourse is D. How this issue does not effect the “central attitude of Pragmatism” is beyond me, since Pragmatism wouldn’t have an intelligible attitude to begin with until a solution is found.
