== The null result of the Michelson–Morley experiment ==


== Violation of Laws of Logic ==
I have removed the [[Michelson–Morley experiment]] from the list of examples.


Claiming "This represents a type of false dichotomy in that it excludes the possibility that there may have been an insufficient investigation to prove that the proposition is either true or false." is a clear violation of the Law of the Excluded Middle.
The reason is that the article makes an unsourced claim that its [[null result]] is "strong evidence" that there is no [[luminiferous aether]].


In other words, the possibilities can only be true or false. Insufficient information is not one of them.[[User:Magnetic Flux|Magnetic Flux]] ([[User talk:Magnetic Flux|talk]]) 03:39, 15 February 2019 (UTC)
I have never seen such a claim, only that the [[luminiferous aether]] cannot explain the observed [[null result]], which is not the same (and which is not a logical fallacy).


:That is exactly right. You are abosolutely correct to point that out. Thats the reason I removed it but someone just reverted my edit without understanding the concept and when I am asking them for reasons they claim there are grammatical mistakes. And that become a valid reason to remove everything I wrote, can you believe that? Man if there is grammatical error then just fix it why remove every single thing?

There are many things I have never seen and a source (notable in the field of physics) making an argument from ignorance regarding this observation would justify reinserting the example. [[User:Lklundin|Lklundin]] ([[User talk:Lklundin|talk]]) 17:42, 22 January 2015 (UTC)

:::Actually if there are borderline cases then that is because the concepts within the propostion were not defined properly enough. Example - "The king of France has blue hair" now in this propostion what constitutes as "'''blue'''"? There are ''many shades of blue,'' so one might be tempted to think that this proposition is a case where borderlines occur and therefore propositions can be fuzzy to some degree. But the problem here is that the concept "blue" or the idea "blue" is '''not properly defined''' here. That is what is causing the problem here. A proposition can be either true or false and if there is some case where its truth value is hard to determine, then its becuase the concepts within that proposition are not well defined. But if thats the case, then it is no longer a proposition. So the point I made seems to me that it still holds.
:::And a propositions truth value being unknowable still doesnt change the fact that it either is true or its false, its merely stating that we cannot access its truth value but we "not being able to access the truth value" doesnt mean that the proposition can have any third truth value.

== Conspicuous Lack of Citations ==
In reading the various sections, there seems to be an abundance of material but with few references. It would be better to be able to be certain that this article isn't just a diatribe by an obsessed person, but a scholarly synopsis with back-up. How can anyone rely on this article? <!-- Template:Unsigned IP --><small class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/24.89.229.157|24.89.229.157]] ([[User talk:24.89.229.157#top|talk]]) 16:16, 9 October 2016 (UTC)</small> <!--Autosigned by SineBot-->

== Confusion around presumption of innocence ==

There is a section in the article on the presumption of innocence which is apparently all original research as it presents no citations. I believe some useful discourse around the presumption of innocence could come into play in the context of the argument from ignorance, but the existing text is opaque on this point. It seems to confuse notions of factual guilt with legal guilt on the one hand, and factual innocence and lack of proof on the other. In factual terms we might say a person is "guilty" in the sense that "he did it" or "innocent" in the sense that "he didn't do it." But the choice in law is between "guilty" and "not guilty", not "guilty" and "innocent." Regardless of issues of burden of proof, a legal finding of guilt is not dependent solely on whether the defendant "did it" but also application of legal categories such as intent. "Guilt" is a legal finding, not a factual finding. This is why in some systems the verdict of "not guilty" is instead referred to (more accurately) as "not proved."

In short, I will DELETE this section but encourage replacement with a more focused discussion - with sources. [[User:Zagraniczniak|Zagraniczniak]] ([[User talk:Zagraniczniak|talk]]) 15:42, 27 March 2018 (UTC)

This edit introduced a level of abstraction that made the intro more difficult to read. The previous version was simpler and more direct, not broken, and hence not in need of repair. I have now twice returned it to status quo ante. Please discuss here instead of edit warring. Just plain Bill (talk) 23:27, 6 June 2018 (UTC)[reply]

Violation of Laws of Logic

[edit]

Claiming "This represents a type of false dichotomy in that it excludes the possibility that there may have been an insufficient investigation to prove that the proposition is either true or false." is a clear violation of the Law of the Excluded Middle.

In other words, the possibilities can only be true or false. Insufficient information is not one of them.Magnetic Flux (talk) 03:39, 15 February 2019 (UTC)[reply]

That is exactly right. You are abosolutely correct to point that out.

This is not how Wikipedia works. See WP:BRD.
Also, there is nothing wrong with the text as it was. There may have been an insufficient investigation to prove that the proposition is either true or false is short for There may have been an insufficient investigation to either prove that the proposition is true or prove that the proposition is false. To assume that the meaning is There may have been an insufficient investigation to prove that the proposition is (either true or false) and that the proposition is a strictly boolean one with no fuzzy borders in the words is to assume that the writer is an idiot. Don't do that. And don't edit-war. --Hob Gadling (talk) 11:13, 17 May 2024 (UTC)[reply]
Actually if there are borderline cases then that is because the concepts within the propostion were not defined properly enough. Example - "The king of France has blue hair" now in this propostion what constitutes as "blue"? There are many shades of blue, so one might be tempted to think that this proposition is a case where borderlines occur and therefore propositions can be fuzzy to some degree.
