| | A distilled recap of the foregoing problematic discussion, along with a "post summary" for each relevant excerpt:
Post 65-(from Rawlings) "Concepts are created by humans to stand for certain types of existents that we observe in reality, types that we specify by means of a definition. Definitions perform two tasks: integration with previously observed reality (the genus) and differentiation within it (the differentia). Thus, a meteorite would be defined as a meteor that has fallen to earth. How is this incomplete or approximate merely because we have not seen every meteorite that ever existed or will exist, or because we do not specify where it lands or how big it is?
So you see, for a concept, completeness or incompleteness is an inapplicable standard in the manner implied. Precision is scarcely more appropriate; since man creates concepts himself, there is never any problem with precision for a concept per se, if one does not demand omniscience."
" ... the essential qualities captured by a definition are merely a means of pointing out what class of existents the concept encompasses."
Post summary: Concepts are thinking tools required for making distinctions of things. In this purpose, their level of completeness is not crucial, but their ability to be used to classify some things within - and from - other known things, is.
Post 68-(from Barnes) "Rodney writes: >So you see, for a concept, "completeness" or "incompleteness" is an inapplicable standard in the manner implied.
So you are simply saying a concept can be neither "complete", nor "incomplete".
Can you see what is wrong with this claim?

Post summary: The inapplicability of a nonessential is the same thing as nonexistence of a nonessential (if it doesn't apply to a regarded purpose, it goes out of existence). Also, the purpose of concepts can be ignored as a standard to judge "applicability."
Post 69-(from Firehammer) "The "meaning" of a concept is only whatever it identifies, and nothing more. How much we know about what a concept identifies is irrelevant. The concept banana identifies the very same thing, whether it is the concept of a child or a botanist.
There is a sense in which the definition of a concept is irrelevant, so long as the person using the word for the concept it represents, knows exactly what existents (whether material or mental) the concept identifies. Definition is only significant when the referents of a concept are in question. Then the definition must be made very explicit to avoid ambiguity or confusion, but this is the exception, rather than the rule.
Rodney suggests you do not really understand the nature of concepts. I think you do, really, but tend to evade that knowledge in your discussions. What do you think?"
Post Summary: A simple and direct question regarding the nature of concepts.
Post 71-(from Barnes) "Regi writes: >Rodney suggests you do not really understand the nature of concepts. I think you do, really, but tend to evade that knowledge in your discussions. What do you think?
Well, Regi, here's the thing: it *is* rather difficult to understand what Rodney is talking about when he insists the nature of concepts is as follows:
Rodney: 'So you see, for a concept, 'completeness' or 'incompleteness' is an inapplicable standard in the manner implied.'
But let me try anyway. To me, this can only mean one thing: that Rodney believes a concept can neither be *complete*, nor *incomplete*. Clearly then, if one is to understand a concept, *one must give up reason in order to do it*!"
Post Summary: A shifty attempt to avoid Regi's direct question by marshalling some nonessentials spoken by another person (revealing note: other's words are not required to answer the question) Picture this: Barnes is on the stand in court and asked about his understanding of concepts. Would his response (that all and only of what he understands about something is that which someone else had once said about it) fly?
Post 72-(from Rawlings) " ... in my sentence
So you see, for a concept, completeness or incompleteness is an inapplicable standard in the manner implied.
you perceive an outright contradiction (applying Aristotle’s rule of the excluded middle apparently!), and ask whether I can possibly really mean it, and that I am confused and do not know what I am talking about. You missed the relevance of the clause “in the manner implied.” This was a reference to my two previous paragraphs, where I pointed out that the implication of your view is that our definition of meteorite is incomplete because we have not seen every meteorite that ever existed or will exist, or because we do not specify where it lands or how big it is.
My response to that was to say that “completeness” in that sense is an irrational standard by which to judge a concept. The idea is inapplicable. Go to the definition of this word—definitions are important—you will see that it means unable to be applied, not appropriate, not fitting, not proper."
Post summary: Concepts are thinking tools required for making distinctions of things. In this purpose, their level of completeness is not crucial, but their ability to be used to classify some things within - and from - other known things, is.
Post 73-(from Thompson) "Daniel, I request that you publically admit that Rodney does indeed have a point regarding incompleteness being an irrelevant standard IN THE CONTEXT OF THIS DISCUSSION.
Of course, you are free to continue to attempt to merely portray his words as if they (in this context) violate the law of the excluded middle, and thereby exempt yourself from having to answer his points - as a shyster lawyer might choose to do. But I would simply like to alert you to the potential for judgment (by myself, and possibly by others) which such action will inescapably entail."
Post summary: Concepts are thinking tools required for making distinctions of things. In this purpose, their level of completeness is not crucial, but their ability to be used to classify some things within - and from - other known things, is.
Post 74-(from Barnes) "You originally said that neither “completeness” *nor “incompleteness”* were applicable to concepts. You’re now saying, however, that only “completeness” of knowledge (or omniscience) cannot be applied as a standard, and indeed, your “every meteorite ever” example shows this very point - that *completeness* of knowledge is an impossible standard to reach, and that we cannot know everything.
Now I would certainly agree with you here ... But by saying this, and by using this very example, you are simply applying the standard of *incompleteness* of knowledge - that we cannot know everything - to concepts (hence, obviously, the necessity for them to be “open-ended” as Mr Stolyarov claimed). Unfortunately, this is precisely the *other* standard you previously insisted cannot apply either!
So you are still very much stuck in the excluded middle, and as I have shown, the context of your example changes nothing, nor did it when I first read it."
Post summary: The inapplicability of a nonessential is the same thing as nonexistence of a nonessential (if it doesn't apply to a regarded purpose, it goes out of existence). Also, the purpose of concepts can be ignored as a standard to judge "applicability."
Post 77-(from Rawlings) "I have not changed my story at all, Daniel—but perhaps my meaning is clearer to you now? Are you satisfied with my “new story”? Do you now understand? If so, do you now agree?"
Post summary: Concepts are thinking tools required for making distinctions of things. In this purpose, their level of completeness is not crucial, but their ability to be used to classify some things within - and from - other known things, is.
Post 78-(from Barnes) "However, it turns out the idea that Rodney and Mr S are parroting - that you need to appeal "omniscience" as a standard if you want to describe human knowledge as “incomplete” - is a false one anyway."
"Therefore, to return us to our original point: Why do you and Mr S insist on "complete" and "precise" definitions (rather than "incomplete" and "inexact" definitions, as I propose) when such standards are either a)inapplicable to (as you claim) or b) not achieveable for (as I have shown) the concepts they are supposed to be describing?"
Post summary: The inapplicability of a nonessential is the same thing as nonexistence of a nonessential (if it doesn't apply to a regarded purpose, it goes out of existence). Also, the purpose of concepts can be ignored as a standard to judge "applicability."
post 79-(from Barnes) "As a one Critical Rationalist I am acquainted with remarked, the IOE is "the worst book Rand ever wrote, not worth the paper its written on". And he should know, being a very enthusiastic Objectivist when he was very much younger (even met Rothbard way back when etc). Underneath it all, it basically is a method of question-begging, which makes it seem - superficially at least - all-answering."
Post summary: People who were Ojectivists when they were younger (especially if they've met people like Rothbard) should know the real value of IOE (others only have uncritical "sentiments"). If you haven't signed on to the Rand bandwagon until after first becoming a wiser adult (or failed to meet influentials like Rothbard), then you missed the boat - you won't have the "gift." Also, you can make claims (e.g. question-begging) without evidential substantiation in philosophical forums (or at least THIS ONE), and you won't have to marshal support for your claims - evidential support is not really very important at all when discussing world views.
