If Respect and Civility are the issues here but someone makes claims that deserve no respect, what is the most civil way to deal with that?

 

Personally, I would deal with that by either making no comment, or saying my opinion is different. And I try to add either IMHO or YMMV.

 

By the way, what claim would deserve no respect? And how do you know a statement is a claim? Would you belittle someone who believed the Earth was flat to their face? Sorry, that just sounds cruel to me.

I have dementia. I save all my posts in a text file I call Forums.  I do a search in that file to find out what I said or did in the past.

 

I still love music.

Teresa, I respect your opinion/s - not just politely, as in true admiration and esteem.:)

In your effort to show that philosophy is not mainly an appeal to authority, you invoke no fewer than five authorities.

 

While I find some topics falling in the realm of philosophy interesting, I dislike the manner in which they are typically discussed, every statement framed as a reference to some authority or other. Besides imposing a needless barrier (reading all those books takes time), it tends to elevate the person above the idea, something I find repulsive. Granted, maths and the natural sciences often name theorems and "laws" after the person who proved or discovered them. Still, when referenced, it is the idea rather than the person which is invoked.

 

A similar cult of personality can be observed on various levels among audiophiles. Ideas are not permitted to stand on their own without the backing of an authority. Challenges to the prevailing dogma are dismissed unless your name is on the list of anointed ones. On this very forum, I have been chastised for daring to question the words of various established authorities.

 

Could it be that some view the audiophile pursuit through the eyes of philosophy, where any notion is acceptable provided it is delivered by an accepted authority, while others, myself included, favour a scientific approach in which persons take a back seat to the ideas under discussion, and these differing approaches are behind the many conflicts we witness here and elsewhere?

 

Nice post. You raise several significant questions, imo. Philosopher Michel Foucault explored  your main question in the essay "What is an Author?". This brief quotation sets the tone: "Beckett supplies a direction: ‘What matter who’s speaking, someone said, what matter who’s speaking.’ " :   http://www.english.upenn.edu/~cavitch/pdf-library/Foucault_Author.pdf

 

It is not lost on me that I have just quoted an author who was quoting an author to raise questions about authorship/ authority.   :/

I think I understand your point, but I think in Philosophy it is more an attempt to give credit to the proponent of the idea, as well as a shorthand way of identifying the idea unambiguously.

 

If we say "Einstein's theory of the photo-electric effect" or "Maxwell's Equations" of "The Schrodinger Equation" or "Planck's Constant", aren't we doing the same thing?

There is a difference. No electrical engineer would describe himself as belonging to the Maxwell school of electromagnetism. Maxwell's equations would be as valid under any name.

I didn't say it was an exact analogy.  But I think you are missing the point by fixating on something that is essentially an artifact.  

 

Let's forget about people's names, then. I agree, it is a distraction.

 

Let us say there exists a proof for a mathematical theorem, and that the idea contained in this theorem winds up being very useful for bridge design and construction.  After several bridges are built, they start to fail under certain conditions, killing several people.  A thorough investigation is conducted, and eventually it leads to the design of the bridge, and ultimately to re-examination of the proof, in which a small logical error is discovered as the ultimate cause.

 

Now, do mathematical proofs have an objective existence, apart from the books they are written in, or the neurological states of the people who have read and worked through the proofs?  You can't weigh the proof, measure an electronic signature of the proof, attribute energy to the proof, etc., so it is tempting to say the poof, which after all was created by (fallible) humans, doesn't have an objective existence apart from the paper it is written down on.  But if that is the case, how can the mistake in the proof have existed prior to its discovery?  If the mistake didn't exist in some objective sense, how could it be responsible for those people's deaths?

No, but I would argue with the person about the merit of the idea.

 

Isn't it more disrespectful to pretend there is nothing to discuss, and just secretly shake your head and say that the person is insane?  

 

Someone willing to argue (in the true meaning of the word) is, implicitly, willing to put the counter-proposal to the test, and is therefore at least entertaining the idea that the flat-earth proposal could be right.

In some sense, one can say that logic, and with it every possible true statement, a subset of which might be termed proofs, "exists" implicitly. All we do is discover it. Then there's of course Gödel's incompleteness theorem to deal with.

 

In your bridge example, it wasn't the flawed proof that killed people, it was the flawed bridge. The mistaken belief that the construction was sound is coincidental.

So what caused the bridge to be built with the flaw, if it wasn't the undiscovered flaw in the proof?  If the flaw doesn't exist until it is discovered, how did the bridge fail?

 

(The point of my example wasn't to get an easy answer to the problem; I don't happen to think there is an easy answer.  But if has to do with ideas that aren't mine.  They could be attributed to Frege, or even Descarte, (or as you pointed out, Kurtie old boy. You made it too easy for me).

This is the very essence of Quine’s take home message. 

 

The folks interested in mathematical proofs and Godels incompleteness etc ought to read and be sure they understand the implications of “Two Dogmas” (which I consider the very best and most important philosophy paper of the 20th century)

 

For those who haven’t yet read, it addresses the question : what are the implications of the so-called a priori truth : “1 + 1 = 2” ... is it?

Does it? Is it? How do you know?

 

What are your assumptions? 

 

Start with: how have you determined that the bridge follows your rules of logic? Is your logical framework flawed?

 

(Eg you are Euclidean +/- aren’t using quantum effects)

 

Essentially Quines take home message, and how philosophy became relevant to physics again.

Isn't bigotry a form of intolerance? Does this bigotry imply hatred?

 

I don't describe myself as a bigot.  You used the word, and the intellectual thug/poser who stalks me parroted it a few times.

 

But to answer your original question as honestly as possible, I admit that I am a bit of an anti-religious zealot.

The bridge follows the rules of physical reality (whatever that is), whether or not we understand them.

 

Same problem:  Do those rules of physical reality have any objective existence, apart from the people who articulate and implement them?  Do the rules exist before they are discovered?

 

(I would say yes, but then I have to account for how their existence differs from that of gods and other such mythical constructs.)

Ok, so where does a “proof”  come into this? That’s the crux. If a proof doesn’t create a perfect bridge, what is its “truth”?

Thanks. Would you also describe yourself as a bit of an anti-subjectivist zealot, or is that too strong? I ask because I read you ask making a kind of correspondence between subjectivism and religion that at times appears to be quite strong.

Why do you keep this line of reasoning up?  In the chain of causes and effects, the 'proof' doesn't fit in. It answers to 'why', not 'how'.

I would like to claim (a) the proof exists somehow as an objective entity, and (b) the mistake existed before it was discovered.  The "how" question is very much more difficult to answer, and I don't think I have a compelling answer.  (I think it is a good example of an open problem in philosophy that has very real implications for physicists and engineers.)

 

My original intention was to demonstrate to Mans that there was more to Philosophy than appeal to the authority of named philosophers (eg: Lucretius), but he beat me to it.

I think it is too strong.  I think you can be a 100% subjectivist (whatever that is) and be an atheist, even a bigoted anti-religious zealot.  Similarly, I see no reason why someone cannot be an 100% objective realist and an ardent believer in a God.

 

I think there are some parallels, but conflating the two becomes problematic (as you imply).

A formal logic system is defined by a set of axioms and derivation rules. A proof consists of showing that a statement (theorem) can be derived from the axioms through the repeated application of rules.

 

Ignoring  Gödel's unprovable theorems for a moment, the other 'truths' within such a system are recursive, i.e., computable. Does that mean that each proof has an existence before it is constructed? Probably not in the physical realm, but certainly in a mathematical sense. All such proofs come into 'mathematical existence' as soon as the formal system is defined.

 

What is curious is that the physical universe appears to be extremely adverse to violating the truths that are derivable in any internally consistent formal logic system. That's why mathematics (a formal system) is such a great tool for modeling physical sciences. Why this is so, is unknown and probably unknowable. Is it by design? By accident? My guess is that the universe itself is just a dynamic formal system trying to randomly construct instantiations of all the possible theorems. In other words, a computer. But I have no proof :)

What is your criteria for truth? Let’s say true = 1. In your logic system does 0.99 = 1? What formal logic system are you using?
