Talk:Hand-waving

message: Question from a non-native english reader: What does handwaving mean in a literal sense? I mean, what movement of the hand/gesture is described by this term? I think this should be added to the article. Thank you. I've done it myself.

thread_title: Literal interpretation - what is the motion?

message: The first definition seems odd:
:"both hands up, palms forward, swinging the hands in a vertical plane pivoting at the elbows and/or shoulders (depending on the magnitude of the handwave)"
I tried doing this, and got no gesture that I have ever seen, more like some sort of dance move or something. What I got was a sort of winshield-wiper motion. Either the definition is wrong, or is poorly expressed. The second definition, listed as a mere alternative, is basically the only one I've seen:
"alternatively, holding the forearms in one position while rotating the hands at the wrist to make them flutter." Herostratus 14:47, 10 July 2006 (UTC)
thread_title:  Definition? 

message: Does this phrase come from Obi Wan Kenobi's famous "these aren't the droids you're looking for" or predate it?
:Predates it. My high school math teacher talked about "handwaving" and "handwavy proofs" (no doubt quoting his own, earlier college teachers) back around 1972. -Potosino 02:18, 20 February 2007 (UTC)
thread_title:  Etymology 

message: I'm almost dead certain that this article used to mention the Jedi handwave.  I think it still should.  Whether that concept was the genesis of this term, or George Lucas came up with the Jedi mind trick gesture as an homage to an existing term, I don't personally know (judging from the "1972" testimonial above, probably the latter), but it's pretty clear that the term's popular currency has a lot to do with Star Wars.  I'm pretty sure that the Jargon File documents this pretty well (though I wouldn't bet my life savings on it; the JF changes a lot over time, just like WP). Anyway, the point was I think this was in there at some point, and now it's not, and that's a shame. — SMcCandlish [talk] [cont]  ‹(-¿-)› 13:52, 23 September 2007 (UTC)

thread_title: Literary Criticism

message: I have reverted two anonymous attempts to add the paragraph
:New York Sports Radio personality Mike Francesa uses the handwave to signal his producers to cut off a caller on his show. This handwave is used in a dismissive manner, letting the caller know that Mike is done with them.
and
:Mike Francesa of Mike'd up and WFAN is a huge supporter of the handwave. Though some may argue he is the original inventor of the handwave, effidence is hard to find. Mike uses the handwave technique to dismiss phone callers from his show.
First, this is an entirely different case of handwave than the one discussed in the article. A dismissive (actual) hand gesture is something entirely different from the (metaporical) handwave in lieu of argument this article is about.
Second, the addition is completely unsourced -- the article in general is not very well sourced (and might not survive and AfD if anyone cared enough to take it there), but attempts to promote a specific named person as a source or prominent example of a cultural phenomenon can reasonably be held to a higher standard of sourcing. We need reliable secondary sources before anybody in particular should be listed as prominent handwavers. –Henning Makholm (talk) 22:48, 6 March 2009 (UTC)
thread_title:  Mike Francesa 

message: This article has no footnotes, citations or substantiation.  The explanations and content range from weak to vacuous.  There appears to be extensive original research and many questionable claims presented as fact while many obvious claims, questions and possible allusions are unaddressed.  
And the central and most basic question remains unanswered: what is the connection between the physical act of hand-waving and this very common colloquial term?  (Does it refer a student waving their hands for attention?  A magician waving her hands to conceal something?  A Jedi waving his hands to cloud someone's mind?  A politician waving her hands to the crowd? ...?)

thread_title:  Excellent self-reflexive article example (unintended) 

message: While there is an apparently 'obvious' genesis of the term, such as the one provided by http://handwaving.askdefine.com/: "The term derives from the use of gestures to add emphasis when stating arguments, and the tendency to continue or increase the gesturing as a substitute for mathematics, when an argument is hard to put across or the proponent is tired of deploying words and/or symbols." , there may in fact be an alternative origin.
George Edward Moore  advanced the idea that one could prove the existence of the world by waving his hands. There are a number of references that I have found which seem to refer to "G.E. Moore's hand-waving" (see for example "G.E.Moore's hand-waving" - Philosophy and Its Others: Ways of Being and Mind By William Desmond , "G.E. Moore's hand-waving" -The Agnostic Inquirer: Revelation from a Philosophical Standpoint By Sandra Lee Mensse and GE Moore Hand-waving argument
None of this constitutes proof that this is the origin of the term, but if you read this website's rationale for its name, then quite clearly there is an undercurrent of thought that would suggest that G.E.Moore's naive argument may have been the origin of the term. I can't find any definite earlier use of the term which would appear to predate his 1939 essay (however, see below), but that does not constitute hard and fast evidence. Interestingly, Moore may have come up with the idea of waving his hands as a response to the skeptical position of Descartes taken in his Meditations: "... I will consider myself as without hands…or of any of the senses, and as falsely believing that I am possessed of these."  --TonyFleet (talk) 10:27, 16 June 2013 (UTC)
