In the OP, you say "what is perceived" and "what exists". — creativesoul
How can you say that these calculations are "pre-rational".
Pre-rational here means these calculations occur before rational thought.
Dr. Nim (the board game/canonically famous, genius, and simple mechanical computer) performs calculations, but does not employ rational thought.This would mean that there is a way of calculating which is not rational.
This is a confused and ambiguous statement. We have an intension (judgment) A; with an extant extension (scenario) B. If you're saying that A's extension (B) would not exist without the formation of the intension A, then it's an absurdity. If you're saying that we cannot have an A referring to an extension B without the formation of the intension A, then it's a vacuous irrelevancy.Plainly and simply, without that judgement, there is no such scenario.
Why do you think it entails natural reasoning? All a comparison requires is a calculation. We can compare variable states on a computer using a comparison operator... computers are (at least generally) incapable of natural language; they calculate, but do not reason.But if you agree that recognition requires such a comparison, how do you think this act of comparison is not an act of "natural reason"?
...so here I say, back up. Why are we talking about this creature seeing things like "objects of food", when mechanically speaking, such a creature would be seeing "a bunch of stimulated cones on a retina"? Once you're talking about objects of food it is impossible for you to have not gone through calculations requisite to identify what parts of those stimulated cones correlate to edges of objects, what parts are part of the same object and what parts are part of different objects, what shapes the objects are, what colors (if applicable), and so on.Suppose a creature sees something as an object of food

I don't think pain is "in your foot," to begin with. — Samuele
For instance, I've never denied the need for a central nervous system, or a brain, in order to feel pain in your foot... or, if you prefer... at the damage site. — creativesoul
I've already addressed the problem with the language you've used to discuss it. You've yet to have given those replies their just due. — creativesoul
I think what InPitzotl is referring to is the rational calculations that take place 'below' the level of language. — A Seagull
Dr. Nim (the board game/canonically famous, genius, and simple mechanical computer) performs calculations, but does not employ rational thought. — InPitzotl
But Dr. Nim is performing calculations. — InPitzotl
The reason isWe have an intension (judgment) A; with an extant extension (scenario) B. — InPitzotl

There's some reason why you're starting at objects, and not stimulated cones. What is that reason? — InPitzotl
When you accidentally kick something with your little toe... are you saying that the pain is not in your toe? — creativesoul
Dr. Nim performs calculations in this sense; it employs a deliberate process that transforms inputs into outputs. But it's not programmed; a program is a set of instructions for a computer to follow, but Dr. Nim has no instruction set.The computer proceeds according to the algorithms by which it is programed, it does not calculate. — Metaphysician Undercover
Consider "the letter A on your keyboard"; for now, that literal phrase. That is a sign. When you read this sign on the screen, you formulate an intension... the idea of what this phrase means. There is a thing to which that idea refers... and that thing is an extension; that is the actual key. What's nice about this example is that there are spatial metaphors that help you keep these things straight... the sign is on your screen. The intension is in your head. The extension is under your left pinky.I'm sorry, but no matter how hard I try, I cannot understand this statement. Can you explain? — Metaphysician Undercover
...and that's the confusion. You're confusing what's under your left pinky with what's being done in the head; what's rolling down the hill with what's happening in the head. The phrase "try to say" means to attempt to formulate a sign; a thing on your screen. "'what' we're sensing" refers to an intension. The conclusion you're reaching, that this implies we're "not talking strictly about sensation any more, but we're referring to some logical conclusion" conflates intension with extension. Intensions are about extensions; that's how this works. Using reasoning is something you do with intensions. The only way that talking about something makes the extension a logical conclusion is if the thing you are talking about is the making of logical conclusions. Merely using logic to reach a conclusion doesn't magically change what you're talking about into the making of logical conclusions, but that's precisely what I'm reading that you said here.as soon as we try to say "what" we're sensing, we're not talking strictly about the sensation any more, but we're referring to some logical conclusion, some reasoning as to "what" the sensation is. — Metaphysician Undercover
Possibly; my best assessment of your criticisms against me is that you're just failing to grasp what I'm saying... up to now it feels more like a definitions fight. But I think my point is really important for someone trying to take a subjective point of view, because from that point of view, there's a huge difference between the things you can access introspectively, and the things you cannot. And there's a lot of stuff going on in your mind before we even get to that arena where your introspective view actually tells you something. The stuff that happens with your signals on your optic nerves that leads up to your percept (aka, "perception")... that's outside of the introspective field. The kinds of things you can reflect on and talk about (aka, natural reasoning)... that's inside.Right, this was exactly my point. Maybe we actually agree.

You do realize that before "computer" was a type of machine, it was a job description, don't you? Calculation is just a more abstract term than you're making it out to be; both Dr. Nim and myself can calculate. Computation, equally so... both the thing your keyboard is connected to, and an employee, can compute. But, yes, mechanical computers calculate in a drastically different way than we do.But the act of "calculating" which a computer does, is nowhere near to being similar to the act of "calculating" that occurs in a living being's act of perception, so the redefining is pointless. — Metaphysician Undercover
...quick side note; it's quite a bit messier than this. Signs quite often, in practice, underspecify intensions (and often, only indirectly convey them); real language use tends to invoke a lot of context.The idea relates directly to the sign, and the sign only.
This critique is incoherent to me. Are you saying, there's no key under your pinky, only a possible key under your pinky?But you misrepresent this application with "a thing to which the idea refers". There is no such thing, only possible things. — Metaphysician Undercover
Huh? What are you talking about? When I convey ideas to you in the forum, I formulate signs by typing. That generates signs on my screen, and eventually generates the same signs on your screen. The signs I type are an attempt to get you to form the same idea. I'm at a total loss what you're talking about when you say I am "finding" the signs, or that they are "fulfilling the criteria of the idea".See your confusion? The attempt to formulate a sign, is an application of the idea, an attempt to find "possible things" (signs) which fufill the criteria of the idea. Therefore it is an extension, not an intension as you say. — Metaphysician Undercover
That doesn't work:This is false. Reasoning is carried out with the symbols (extensions),
...when describing world objects, the extensions are those world objects. When you reason about world objects, those world objects are not symbols, and you don't reason "with" them (I suppose you could; if we want to call that reason... if, say, I'm making use of a calculator, I'm reasoning "with" a calculator, but I suspect this isn't what you mean). You reason with your ideas about those world objects. (Now that can be comprehensions, but it's never going to be an extension, so long as you're talking about world objects).Extension (semantics) the extension of a concept, idea, or sign consists of the things to which it applies ... So the extension of the word "dog" is the set of all (past, present and future) dogs in the world: the set includes Fido, Rover, Lassie, Rex, and so on — Wikipedia
I've no problems with this.Forming an idea is intensional, while applying the idea is extensional.
Well... except that makes the term "sensing" a not so tidy concept.All I am saying is that this "stuff going on in your mind" is better represented as a type of "reasoning" (though it may not be conscious reasoning), than it is represented as "sensing".
How is that different than what's already on the table... just calling it some other thing, like, "perception"?Perhaps we'd be best off to compromise, and conclude that it is neither sensing nor reasoning. — Metaphysician Undercover
