Michael:

One attribute of an existent is its own existence. Another is its own uniqueness. These happen to be the first two axiomatic concepts (existence and identity). They are inherent to and transmitted together with all initial sensory stimuli.

 
 
This is oft-repeated, like a mantra, but I do not recall ever denying existence and identity. Of course every existent has its own existence and identity. But so what? Conscious beings don't automatically know, as if by divine revelation, what that identity is!

To tell us, yet again that existence exists and existents have identities is to state that which is obvious and already implicit in "identification" as though it had some magical meaning that would become plain if only we repeat it often enough.

There is a process by which identification occurs. The question is: What is that process?

However, on a non-conceptual level (please bear with me and use traditional terminology here, not the new one you want to have accepted), these basic attributes are "integrated" into the perception of the existent - and thus into the ensuing basic physical mental unit, the initial percept, from which higher ones will be integrated.


All you're doing is repeating the formula and ignoring the questions I put to you:
  • How can things be "integrated" unless they are first DIFFERENTIATED?
  • How can things be differentiated unless the identity of the differentia are known?
  • How can something (differentium) be identified without a classificatory concept?
If you cannot actually answer those questions, an "I don't know" would suffice. But "attributes are integrated" and "mental units" is to state the obvious and ignore the details.

A deer does not need to conceptually understand that a lion exists, a very particular mean and hungry lion, in order to automatically integrate those two axiomatic facts and haul ass out of there.

The deer will even remember to do it again, only faster this time.


 
 
I'm forced to disagree. If a deer can identify the difference between another deer and a lion, it is classifying, and that is one of the earmarks of conceptual thinking.

Hell, Nathan, if you think differentiation is the all-determining element of a concept, instead of one of the elements to be integrated by a brain from individual instances compared against stored "mental units" (memory), then the sense of hearing, for example cannot process light waves not because it has a specific nature, but because it is "conceptual" in nature.

Sorry, I can't make that leap.

Nathan, your thinking error is not that you disbelieve in that which is axiomatic--it is that you do not currently integrate particulars while holding axioms in context (for the purpose of noncontradictory integration).

An example of this thinking error was your response to my small room example, the room that the pony would barely fit into.

With me in the room (250-lbs of muscle and brain tissue), it would be a physical impossibility for the pony to ALSO be in the room--yet you deny this impossibility. You fail to integrate axioms in your thinking. Existence Exists means things are what they are, and Existence is Identity means that the same things will continue to be what they are--through both time and space (location). You're failure to see this error is why I had recently cut off discussion with you, on this matter.

Another example of your failure to integrate here is how your main questions can be almost entirely answered by past quotes from either Gibson, Rand, or myself (in this thread)--ie. new information is not needed to answer these old questions of yours (new integration is):

-----------------------
Old Question 1
* How can things be "integrated" unless they are first DIFFERENTIATED?
-----------------------
"We don't perceive identities, but properties. Perception is not identification [not in the essential characteristic, conceptual common denominator sense of identification--ie. true, objective, conceptual identification], conception is. While we do perceive entities, we do not perceive that we perceive them--we conceive of this"

"'The perception of what a thing is [ie. the perceptible properties of things, not the essential characteristics of things, not the conceptual common denominator of things, as they are related to other things] and the perception of what it means are not separate, either. To perceive that a surface is level and solid is also to perceive that it is walk-on-able.'"

-----------------------
Old Question 2
* How can things be differentiated unless the identity of the differentia are known?
-----------------------
"... by merely examining particulars--while holding context."

" ... by examining particulars against a reference standard."

" ... all that the perceptual level is capable of is awareness of "unidentified" particulars ... "

"We also have certain knowledge [certitude] of the relations between ... things conceived of, after having become aware of them--in our perceptual field (this stone is larger than that) ..."

" ... we know what a thing is, only in relation to what it is not--knowledge is a relational phenomenon"

"Not to beat a dead horse here, but I do not need to know all there is to know about the pony (or say, pony-ness) in order to accomplish this task. I need only be able to conceptually discern ponies from TVs, ponies from sofas, and ponies from lamps."

"We know it, even if we don't, in actuality, know everything about it--such as its trillionth digit, for example (though, we can, in principle and potentially, know as much about it as we yearn for--because we know what it is, and is not, among everything else known). We know it because of its unique place among other known things. We have a veridical conceptual discernment regarding what it is that pi is. Therefore, our knowledge of it cannot ever be false."

"Perceptual experience is a direct pickup of exactly what it is that is in our environment. Conceptual powers (which can err, but can be made not to) identify what it is that the perceptions are about."

"You're right, Nathan. It is not possible to hold a concept without differentiation. It was merely a useful redundancy for me to speak of conceptual discernment--to hammer the point home that correct concept formation automatically yields knowledge."

"Concepts are not beliefs--concepts are that by which we are aware of contrast in the world."

"Omniscience is not the standard, effective differentiation is. We can be certain (having certitude) of how something relates to other things [insert knowable relation here; such as black being darker than white, etc]"

"While the REASON that the [black-darker-than-white] proposition cannot be false (it has certitude) stems from the basic [wavelengths of light--and our visual apparatus], the "informative" aspect stems from how we think about the [wavelengths, as viewed by us] (concepts), not from the previously-unintegrated [wavelengths] themselves."

"A key underlying theme of my essay is that knowledge is relational (we need only to effectively discern relations--in order to be in possession of knowledge)."

[This was actually a trick question that presumes a knowable identity (ala innate ideas) BEFORE differentiation--omniscience as a requirement for knowledge--ie. it precludes the possibility of human knowledge. At any given context of knowledge, we are RELATING things known to new knowable things. Rand's example of the changing, though always contextually true, definition of man--throughout an agent's development; such as an infant (tall, moving things) who grows into a rational adult (rational animal)]

-----------------------
Old Question 3
* How can something (differentium) be identified without a classificatory concept?
-----------------------

See above.

I think it's a necessary component, not a sole determinant.

instead of one of the elements to be integrated by a brain from individual instances compared against stored "mental units" (memory),
 
The brain is not integrating "differentiation," Michael. It is integrating differentia.

 
The question--the still-unanswered question--is how does the mind know how to integrate the differentia unless it has identified them, and how can it identify them with no concept as to classification?
 
then the sense of hearing, for example cannot process light waves not because it has a specific nature, but because it is "conceptual" in nature.

Sorry, I can't make that leap.


 
 
The sense of hearing, presented with the data the eyes normally send to the visual cortext, could not process the data for two reasons:
  • It is not in the form the auditory portion of the brain can use, i.e., the ear does some preprocessing, and
  • Some of the cognitive processes required for vision are different than those for sound. With vision, for example, we have a hard-wired innate concept which allows us to distinguish the edges of objects. This would not likely be present in auditory processing. 
But you still have the same problem: How does one differentiate and integrate sound without concepts which permit classification?

Nathan,

Finally, here's the rub.

Are you trying to tell me that the ear cannot process light waves because it is not in the nature of the organ and parts of the brain that process sound to do that?

Are you sure? Living organs can have a specific nature that isolates them from total experience? This is not due to a faulty concept or something? 

Do you mean that sound might exist and have a specific identity with a specific nature? And the sense organ and part of the brain that deals with sound might exist and have a specific identity and specific nature too?

So how about having a thing called "memory" that might exist and have a specific identity too? With its own specific nature? And the "mental units"?

I will even give you the possibility of creating a "mental unit" out of one sensation only, without differentia yet. Just data that went into the brain, was transformed into a mental unit and was stored as a memory.

That stored unit would be what is compared against new similar data. (Then integrated, when that time comes.)

So - what determines what type of data can get compared against the stored data?

Back to the sound and light waves again. The nature of the organic hardware is what.

The capacity to distinguish between different instances of different data does not come about from a "pre-learned" state. It is inherent in the organs themselves, like sound and light processing.

Gotta start somewhere.

Existence does exist you know. And different things are different. We perceive two different things, then process them because our organs have the capacity to attribute different signals to different things, not the other way around.

But one other way can go too. The capacity to identify two or more of the same things is also inherent in our organs.

That plus memory is where integration begins.

Michael


Edit - I would even postulate that the physical shape of mental units is determined to some extent by the nature of the sense organs - and that the organs themselves evolved in the manner they did because their forms and products were very successful in processing data.

Oh, dear, yet another invocation of the mantra: "Existence Exists means things are what they are, and Existence is Identity." The magic wand.

(You act as though those axioms somehow ensure perception.)

Another example of your failure to integrate here is how your main questions can be almost entirely answered by past quotes from either Gibson, Rand, or myself (in this thread)--ie. new information is not needed to answer these old questions of yours (new integration is):


Prove it. I'm afraid your "integrations," Ed, are largely imaginary. But let's see if you actually talk about issues, or continue to discuss my alleged thinking processes.
 
Old Question 1

Nathan asked:
 
* How can things be "integrated" unless they are first DIFFERENTIATED?
 

Ed wrote:
 
"We don't perceive identities, but properties. Perception is not identification [not in the essential characteristic, conceptual common denominator sense of identification--ie. true, objective, conceptual identification], conception is. While we do perceive entities, we do not perceive that we perceive them--we conceive of this"
 
 
 
Do you actually imagine this answers the question?

How do you suppose that we differentiate the properties in perception unless we identify them?

If shown a picture of the Mona Lisa, how would you know where her wistful smile begins and ends without some knowledge of lips, or at an earlier age, without some innate knowledge of edges and objectifying things within boundaries?

You're not answering the question, you're just restating dogma. PROVE that we can somehow "perceive properties" without identifying them!

We SENSE the raw data of properties, but we do not perceive them without classification, identification. Otherwise, how could you tell one property from another?

 
"'The perception of what a thing is [ie. the perceptible properties of things, not the essential characteristics of things, not the conceptual common denominator of things, as they are related to other things] and the perception of what it means are not separate, either. To perceive that a surface is level and solid is also to perceive that it is walk-on-able.'"
 

Same problem.

How do you tell one property from another without identifying them?

How do you distinguish solidity from softness and levelness from tilted without a concept of solid and level?

How do we "directly" perceive that something is "walk-on-able" without employing the concept of walking? With no concept of those conditions which would prohibit walking?

This is just more hand-waving, Ed. It's trying to "answer" my questions with the equivalent of "it just does."


Old Question 2

Nathan asked:
 
* How can things be differentiated unless the identity of the differentia are known?
 
 
 
Ed wrote:  
"... by merely examining particulars--while holding context."
 
 
Another non-answer. To "How do we know what we're looking at? you're answering "We just look."

Only now you're introduced "holding context" into the formula. How do we know the nature of the "context" without identification?

This is all rather mystical-sounding.
 
" ... by examining particulars against a reference standard."
 

There's that circular "examining" again.

You are saying that you're comparing one unclassified, unidentified thing against another?

Are we comparing the "particulars" against EVERY possible reference we have in our minds, or do we select?

If NOT, if we select, by what process do we select the unidentified, unclassified "references"?

Ed, I'm afraid you're just throwing words at these questions without understanding their significance.


" ... all that the perceptual level is capable of is awareness of "unidentified" particulars ... "

 

But didn't you just tell me that it is aware of "reference standards"? Which does it select if these are unidentified?

And didn't you just tell me it is aware of properties like "walk-on-able, which implies an awareness of walking?
 
"Perceptual experience is a direct pickup of exactly what it is that is in our environment. Conceptual powers (which can err, but can be made not to) identify what it is that the perceptions are about."
 

You're just repeating the position, Ed, not proving it. When you can actually ANSWER the questions I posed, instead of responding with a restatement of assertions and the equivalent of "we just do," perhaps you can break out of your circular thinking.

After this, I see no point in restating questions you are not really answering.

Some interesting questions.

Finally, here's the rub.

Are you trying to tell me that the ear cannot process light waves because it is not in the nature of the organ and parts of the brain that process sound to do that?

Are you sure? Living organs can have a specific nature that isolates them from total experience? This is not do to a faulty concept or something? 


 
 
Certainly sensory organs are specialized in the stimuli to which they respond, to state the obvious.

So that takes us to the mind. Some parts of it, and the brain, are general purpose, while other are specialized.

This is demonstrated by brain-injured people. Some lost functions can be assumed by uninjured portions of the brain, while some cannot. 

Could those portions of the brain devoted to processing sound reorganize themselves to process vision? My best guess is probably not, though I'd have to consult neurological studies to speak with more conviction.  

Why? Because that aural portion of the brain probably has no concept of edges and visual integration. It likely comes equipped with innate concepts of space, in the same way vision does--experiments with infant cognition suggest this. But I'd be surprised if the two faculties shared enough properties for brain region re-education.


Do you mean that sound might exist and have a specific identity with a specific nature? And the sense organ and part of the brain that deals with sound might exist and have a specific identity and specific nature too?

So how about having a thing called "memory" that might exist and have a specific identity too? With its own specific nature? And the "mental units"?


I'm not sure what you're asking. I've made it fairly clear that I'm aware of brain and sensory specialization. How does that relate to whether perceptions involve conceptual processes?


I will even give you the possibility of creating a "mental unit" out of one sensation only, without differentia yet. Just data that went into the brain, was transformed into a mental unit and was stored as a memory.

 
 
That's not possible. From the moment a cell senses a datum, it is sensing difference--it's own particular brand of difference. Unless the brain or nervous system is interpreting "differentia" from the very outset, no sensation (other than at the cellular level) is taking place.

Differentia are automatic, a function of the nature of the sense organs and the stimulus, and of the mapping of stimulus to mind.

Where the Objectivist epistemology falls apart is in the INTEGRATION of those differentia--it is not possible to organize differentia into perceived properties without some knowledge of how data can be meaningfully organized! That's classification and that's conceptual.

If we were to load a JPEG image onto the hard drive of an old DOS machine, would we expect the computer to know what to do with it, how to interpret it and render it as an image on the screen?

We could load it into memory using a debugger like DDT, but what would the computer do with that data?

DDT could dump a hex listing of the memory block onto the screen, but so what? It would be meaningless in terms of the image.

We could write a program that differentiates light areas from dark, and red areas from blue--a model for senses, actually, but even though the machine now can identify differentia, what is the SIGNIFICANCE of those differences?

Do two red patches go together as a property such as lips might exhibit, or do those two red patches not go together, like two apples in a bowl?

How, without identification and classification, do perceptions organize the data? Our old DOS computer can't do it with only differentiation, and neither can we.


That stored unit would be what is compared against new similar data. (Then integrated, when that time comes.)

So - what determines what type of data can get compared against the stored data?


 
 
Exactly one point I made for Ed. Our minds are filled with a vast array of experience. How do we know what to compare incoming data with without a means of identifying properties and references? Do we search our entire mental "hard drive" for every perception, or do we identify properties and narrow the search?

IDENTIFICATION: That's part of conceptual thinking, and perception can't even get off the ground without it. That fact MUST be grasped.


Back to the sound and light waves again. The nature of the organic hardware is what.

The capacity to distinguish between different instances of different data does not come about from a "pre-learned" state. It is inherent in the organs themselves, like sound and light processing.

Gotta start somewhere.


Some organs do preprocessing, like the ear. The eye as well. But that's just differentiation. And it's still just raw data.

To even BEGIN to be integrated the data requires an identificatory process. Rand recognizes that perceptions integrate, but she failed to recognize that integration requires identification--because she was reserving that for concepts.

She was partly right, that's part of conceptualization. But that necessarily makes perceptual activity CONCEPTUAL.

If she had asked herself, "How can data be organized into properties without identification?" perhaps she would not have posited a false Percept/Concept dichotomy.

Existence does exist you know. And different things are different. We perceive two different things, then process them because our organs have the capacity to attribute different signals to different things, not the other way around.

But one other way can go too. The capacity to identify two or more of the same things is also inherent in our organs.

That plus memory is where integration begins.


 
 
As I've noted, our sense organs do have some discriminatory power. But I deny that they have any substantive power to interpret or identify data.

Consider the eye. As I said in another post, one can have perfect vision sensorily and lose the capacity to interpret what you are seeing, or even to PERCEIVE what you are seeing, i.e., bring it into one's awareness. There is MUCH data on this.

If you're claiming that perception occurs at the organ level, I'm afraid that cognitive science is largely going to repudiate your hypothesis. The science is just not there.

I enjoyed your questions, Michael.

Nathan, without much hope, I have attempted to answer you more thoroughly …

 

 

 

Ed:


Nathan, your thinking error is not that you disbelieve in that which is axiomatic--

 

 

Nathan:
”Which axiom do I disbelieve?”

 

Nathan, you don’t disbelieve in axioms—as I stated above in the quote.

 

 

 

 

 
it is that you do not currently integrate particulars while holding axioms in context (for the purpose of noncontradictory integration).

Nathan:
”That's another way of saying that I'm ignoring something.

What?”

 

Nathan, you were ignoring the limitations which axioms impose on what can be true of the world. I returned to the small-room/pony example in order to make this clear to you. If a room could barely hold a pony, AND a large man enters THAT room, THEN there cannot, in any plausible circumstance, be enough space in that room for the pony as well as the large man—THAT is a noncontradictory integration of experience with axioms. THAT is what you failed to do when you said that I can’t be sure—while occupying the room--that the pony is not also in the room with me.

 

 

 

 


An example of this thinking error was your response to my small room example, the room that the pony would barely fit into.

With me in the room (250-lbs of muscle and brain tissue), it would be a physical impossibility for the pony to ALSO be in the room--yet you deny this impossibility.

We SENSE the raw data of properties, but we do not perceive them without classification, identification. Otherwise, how could you tell one property from another?”

 

Nathan, take the Morning Star-Evening Star-Venus example: where 2 unidentified particulars were later “identified,” in the “essential characteristic” sense of the term. They were identified (in this strong sense of the term), by our conceptual faculty, and not via perception—as one and the same planet, Venus. We finally have now conceived that we had been perceiving one and the same planet. Perception had afforded us with 2 unidentified particulars (contextually pre-differentiated perceptual instances). Utilizing our conceptual powers, we were then able to integrate these 2 unidentified particulars into a single, overarching identification of a single, orbit-traversing planet; aka Venus. Nathan, I truly hope that that answers your question—I fear that I cannot make it any more clear than that.

 

 

 

 
"'The perception of what a thing is [ie. the perceptible properties of things, not the essential characteristics of things, not the conceptual common denominator of things, as they are related to other things] and the perception of what it means are not separate, either. To perceive that a surface is level and solid is also to perceive that it is walk-on-able.'"

 

Nathan:
”Same problem.

How do you distinguish solidity from softness and levelness from tilted without a concept of solid and level?

How do we "directly" perceive that something is "walk-on-able" without employing the concept of walking? With no concept of those conditions which would prohibit walking?”
------------------------------------------------------------------------------------------------------------

Nathan, by time- and motion-sensitive perception; by memory of past experience; and by vulgar association of these memories, with our current perceptual experience (ie. by our perceptual powers of awareness).

 

 


Old Question 2

Nathan asked:

* How can things be differentiated unless the identity of the differentia are known?
 

 

 
Ed wrote:

 Nathan:
”Another non-answer. To "How do we know what we're looking at? you're answering "We just look."

Only now you're introduced "holding context" into the formula. How do we know the nature of the "context" without identification?”

 

Nathan, when I specifically said “examining,” I meant conceptually examining—ie. looking for relations, looking for differences (and therefore, a lack of difference--which is conceptualized as a contextual similarity), and looking to integrate. Man, are you ever a pedant! Perhaps I shouldn’t use the word “look” here—because I fear that it only tempts you further, to pounce on your prey (me) in pedantic, perturbed, projection; postulating that I must have meant to literally “see” (with visual apparatus) these things. That’s what I now expect from you, Nathan—sophistry, straw men, and subversion of any simplifying synopsis which I can muster (to make understanding of this matter more clear to YOU). I certainly do not look forward to conversing with you on THIS subject.




 

 
" ... by examining particulars against a reference standard."

 

Nathan:
”There's that circular "examining" again.

You are saying that you're comparing one unclassified, unidentified thing against another?

Are we comparing the "particulars" against EVERY possible reference we have in our minds, or do we select?

If NOT, if we select, by what process do we select the unidentified, unclassified "references"?”

 

Nathan, it’s not circular if you separate the perceptual from the conceptual. The reference standard is conceptual in nature. Any talk of any standard is conceptual talk. I separated the 2 main powers of awareness in my essay and follow-up discussions. You are conflating the 2 main powers of awareness (which is no surprise, hell that is your “hypothesis”!). Do not merely project this hypothesis on to me (I do not hold it), and then merely judge the insights provided by my essay and follow-up discussion—by whether or not it fits in with your hypothesis (who is being circular here?).

 

 


" ... all that the perceptual level is capable of is awareness of "unidentified" particulars ... "

 

 

Nathan:
”But didn't you just tell me that it is aware of "reference standards"? Which does it select if these are unidentified?

And didn't you just tell me it is aware of properties like "walk-on-able, which implies an awareness of walking?”

 

Nathan, see above.

 

 

 

 

 
"Perceptual experience is a direct pickup of exactly what it is that is in our environment. Conceptual powers (which can err, but can be made not to) identify what it is that the perceptions are about."
 

 

Nathan:
”You're just repeating the position, Ed, not proving it. When you can actually ANSWER the questions I posed, instead of responding with a restatement of assertions and the equivalent of "we just do," perhaps you can break out of your circular thinking.”

Edit
Nathan,

Since the beginning I have claimed that the problem here is semantic. You wrote:
Rand recognizes that perceptions integrate, but she failed to recognize that integration requires identification--because she was reserving that for concepts.

She was partly right, that's part of conceptualization. But that necessarily makes perceptual activity CONCEPTUAL.
It has been a while since I read ITOE for the last time and I have not yet gone out and bought a new copy of it, but I cannot remember anywhere at all where Rand posited that integration occurred without identification, even of sensations and percepts.

Now of course you have a different definition of percept than the one she used and you want to call the whole shebang concept, as if Rand's idea of percept was a whole different animal from concept, not part of the identification and integration chain.

Call it what you like, I get the feeling that we are talking about the same things with different words only.

Also, you have mentioned including a process you call "organization" in this. As an attribute of living cells, I will certainly buy that. Even digestion has "organization" built into it. All life does.

Actually I feel closer to what you are talking about than the "non-physical existence" stuff for human consciousness. Our problem is in what to call it, not whether the "it" has an intelligible form or not in the physical reality inside our brain.

To me, that stuff is spooksville. I have a real problem with non-physical "essences."

On reflecting on this though, I did come across an interesting thought. That is the difficulty of arriving at the exact physical form of a specific consciousness, such as yours or mine, in order to be able to reproduce it. I do believe that one day we will create a consciousness in the lab from inorganic matter, just as we will life. But creating a specific one will be just as hard as creating an exact specific anything. And that will be the case so long as subatomic articles continue in movement.

This can be seen as especially true for feet. Your right foot and my right foot may be different in many particulars, but they similar in enough of them to be called the same thing. If we reproduce a right foot artificially and somehow breathe the footness of life into it, we might get a good right foot, but we will never get your foot or mine. So it looks like we are stuck with our own feet for now...

Ed:

 

I don't think we're going to get anywhere, but I'll have a quick run through this and see if I can find a glimmer of a break-through.

 

Nathan, you were ignoring the limitations which axioms impose on what can be true of the world. 




 
I'm not sure what you're trying to discuss, percepts/concepts, or certitude.



In either case, your pony example proves nothing I can discern.

 

 

 

”Oh, dear, yet another invocation of the mantra: ‘Existence Exists means things are what they are, and Existence is Identity.’ The magic wand.

Where, PRECISELY, did I fail to ‘integrate’ that?

(You act as though those axioms somehow ensure perception.)”


 

 

Nathan, see above.




 

So you DO believe that your axioms somehow enable perception. 

 

I don't suppose you will bother to explain how perception uses axioms if perception doesn't use concepts.

 

 

Same problem.

How do you tell one property from another without identifying them?

How do you distinguish solidity from softness and levelness from tilted without a concept of solid and level?

How do we "directly" perceive that something is "walk-on-able" without employing the concept of walking? With no concept of those conditions which would prohibit walking?”

 

Nathan, by time- and motion-sensitive perception; by memory of past experience; and by vulgar association of these memories, with our current perceptual experience (ie. by our perceptual powers of awareness).
 

 

Ed, you just keep shuffling the same problem off onto another claim which has the same problem.

 

Reminds me of the infinite-regress flaw in the Intelligent Design argument.

 

Your answer to my questions takes the form "by memory of past experience" which has exactly the same problem--how do we distinguish one memory from another and compare it to our sensate data without IDENTIFICATION and CLASSIFICATION?

 

[Personal attacks snipped.]

 

 

Nathan, it’s not circular if you separate the perceptual from the conceptual.

 

 

 

No, it certainly isn't.

 

Which is itself a circular, question-begging statement. Remember, the ISSUE is whether or not percepts and concepts are the same. Not you wish me to assume that they are NOT, smuggling the conclusion into your premise.

 

Ed, on that lovely note, and your resumption of personal attacks, I leave this discussion.

Michael:

Since the beginning I have claimed that the problem here is semantic. You wrote:

Rand recognizes that perceptions integrate, but she failed to recognize that integration requires identification--because she was reserving that for concepts.

She was partly right, that's part of conceptualization. But that necessarily makes perceptual activity CONCEPTUAL.
It has been a while since I read ITOE for the last time and I have not yet gone out and bought a new copy of it, but I cannot remember anywhere at all where Rand posited that integration occurred without identification, even of sensations and percepts.

 

In the absense of evidence to the contrary, I'm not assuming that she made the outright claim "that integration occurred without identification." I didn't say that.

I'm fairly certain that:

1) she said perception requires integration (if memory and the quotes in the threads are correct), and concluding

2) that she simply failed to make the connection that --> integration requires indentification or classification --> classification requires concepts by her own definition.

I suspect that she was so driven by her distaste for the humanity-bashers (and I can't blame her) that she was driven to find something special about human nature, and what better divide than concepts as a special, human-only faculty unshared in principle with any other form of life on Earth.

In her shoes, given her background, I might have made the same mistake. But, unfortunately, it IS an error, in my view, and has no basis in fact. Reality is what it is, whatever Ayn Rand says.

Now of course you have a different definition of percept than the one she used and you want to call the whole shebang concept, ... 
 
What you're failing to recognize is that by Rand's own definitions and logic (excluding the gaps and errors) she would be forced to concede that conceptual thinking is required for integrative percepts to function.

as if Rand's idea of percept was a whole different animal from concept, not part of the identification and integration chain.

 

I don't quite understand this. Ayn Rand claimed they were whole different animals. She said that man's special faculty was conceptual, and animals functioned only on a perceptual level.

My recognition that perceptual thinking entails the conceptual simply fills in a gap in her thinking and exposes some non sequiturs.

Of course, this recognition, even if trivial, is important if Objectivist epistemology is actually to match the facts of the real world, not the least of which is the actual nature of human and animal psychology.

Call it what you like, I get the feeling that we are talking about the same things with different words only.

 

I'm afraid Ayn Rand would probably disagree with you. You may recall my response to Jordan's question about how we would test the respective positions.  I pointed to the consequences of each for animal and human psychology.

Ayn Rand understood the consequences of her position. That's why she denied that animals can behave conceptually. Unfortunately for her position, the science is proving her view incorrect.

Also, you have mentioned including a process you call "organization" in this. As an attribute of living cells, I will certainly buy that. Even digestion has "organization" built into it. All life does.

Actually I feel closer to what you are talking about than the "non-physical existence" stuff for human consciousness. Our problem is in what to call it, not whether the "it" has an intelligible form or not in the physical reality inside our brain.

 
To me, that stuff is spooksville. I have a real problem with non-physical "essences."


 

Sure. I have seen absolutely no evidence that anything but normal matter/energy and the patterns superimposed thereon are involved in life or intelligence. Anyone who asserts otherwise has the burden of proof, but I don't see how the undetectable can be proven, or how the detectable would be anything else matter/energy/organization. But then I don't understand quantum entanglement, either.

On reflecting on this though, I did come across an interesting thought. That is the difficulty of arriving at the exact physical form of a specific consciousness, such as yours or mine, in order to be able to reproduce it. I do believe that one day we will create a consciousness in the lab from inorganic matter, just as we will life. But creating a specific one will be just as hard as creating an exact specific anything. And that will be the case so long as subatomic articles continue in movement.


Work is underway on mind-mapping, which should become the next "genome project." Non-invasive brain-mapping instrumentation is doubling in resolution and sensitivity every year or two, if memory serves.

This can be seen as especially true for feet. Your right foot and my right foot may be different in many particulars, but they similar in enough of them to be called the same thing. If we reproduce a right foot artificially and somehow breathe the footness of life into it, we might get a good right foot, but we will never get your foot or mine. So it looks like we are stuck with our own feet for now...



The "footness of life." I like that.
 
We could conceivably, in just a few years, perhaps even now, grow clones in vats with genetically-identical limbs and organs. Assuming the irrational fanatics allow such things to be legal.

Pi is the result of dividing any circle's circumference by its diameter... another way of knowing it.

Dean,

Knowing this way of discerning what pi is (by dividing any circle's circumference by its diameter) affords genuine knowledge. The reason that it is genuine knowledge (and not mere opinion) -- is because how it is known, is known. When you know how you can know things -- then you truly do know things.

This is just the definition of pi; how much 'genuine knowledge' is there in a definition?

None.

Indeed, that's the trap where Objectivism got stuck. Ayn Rand thought she deduced a metaphysical system from the tautological definition "A is A"...

No Objectivist can admit that and remain an Objectivist.

Lets say that you want to know the ratio of one circle's circumference to another one's, exactly, and you know both of the circles' radii. How would you do it without pi? Pi is one of the most useful real numbers. So is 'e'.

Did you know that:
cos(2*pi*t) = (e^(2*pi*i*t) + e^(-2*pi*i*t))/(2)
sin(2*pi*t) = (e^(2*pi*i*t) - e^(-2*pi*i*t))/(2i)

Those equations utilize all sorts of definitions. They are all crucial to the signal processing, linear systems, and control fields.

(A molecule with) atomic number 2 (is what helium is.) 

Once you know that a given molecule is helium, if a lab mate tells you that that same given molecule has atomic number 2, he provides you no new "knowledge."

In the same fashion, if you know what the constant pi is, of course you know its definition. 

That's what I meant in post #74. Sorry if I did not put it explicitly enough.
