Further my post dt. Mar 25, 2014 3:44 PM (http://mathforum.org/kb/thread.jspa?messageID=9419089?), it struck me that the definition I had provided for Robert Hansen's "cock-suredness" (sic) was somewhat inadequate. I therefore show, below my signature, a more detailed look at the definitions in two major dictionaries.
I have provided links to the respective dictionary definitions, and I'd strongly advise that one should actually go there and examine examples of the actual 'usages' of the word, specifically in respect to my claims here below.
1. The word "cock-suredness" does not exist. OK, it's a clumsy neologism, but that is not so important.
2. The real issue here is that a person possessing even a 'reasonable command' over English ('figures of speech', etc) simply would not and should not use it as an adjective describing the noun "insight", as for example, "cocksure insightfulness" (or, as Mr Hansen would have it ""cock-suredness insight"). In fact, the only reason one would have to be 'cocksure' about one's claimed 'insights' would be if one were rather diffident about the validity of those insights.
It ("cock-suredness insight") is not quite an 'oxymoron' - but it is certainly an extremely unintelligent and graceless use of language.
As a 'figure of speech', one would only laugh at it and conclude that the person who uses such figures of speech does not possess a grip of the language or even of his/her own ideas.
