I think everyone cares when they are on that operating table. They sure hope that there is a right way to transplant a heart, for instance. — mrcoffee
Yes I agree that logic is impossible without this fundamental first step. But if contradiction is inherent within the first step, don't you see this as a problem? — Metaphysician Undercover
The first law is the law of identity. — Metaphysician Undercover
The second law is the law of non-contradiction. — Metaphysician Undercover
Aren't we obliged to either forfeit the law of non-contradiction, or go back to our mode of identification and rectify this problem of contradiction inherent within identification? — Metaphysician Undercover
I'm no mathematician, but I've noticed that set theory has contradiction inherent within it as well. — Metaphysician Undercover
I do not believe that the resolution to the problem of contradiction being inherent within the first step, is to introduce other contradictions to cover it up. — Metaphysician Undercover
To demonstrate imperfections within something is to demonstrate that it is less than ideal. It is not necessary to show the ideal, in order to demonstrate that what we have is not ideal. — Metaphysician Undercover
To demonstrate problems within a system does not require that one put forward resolutions to the problems. — Metaphysician Undercover
I'm not sure that we have a problem. We can distinguish between the individual marks and then categorize these marks. For instance, let A = {s2e, 2rt, e42}. Let f be defined on all strings over lower case letters and decimal digits so that f(s) = 0 if s does not contain the symbol 2 and f(s) = 1 if s does contain the symbol 2. Then f(s2e) = f(2rt) = f(e42) = 1. A less formal example would be three different dogs, each recognized as belonging to the category 'dog.' I can only offer this example because we already understand this category 'dog.' My formal example suggests how math basically scrubs 'ordlang' logic of its ambiguity, which is gets from our fuzzy language, so that it's structure can be focused on and examined. — mrcoffee
To me this is far from obvious. How do we evaluate/demonstrate the relation 'less than' without an image of the ideal? I will agree that we can prove the impossibility of certain systems. — mrcoffee
But if we consider possibility (that the system works) to be an essential feature of the ideal, then I don't currently see how we couldn't immediately institute a particular vision of the ideal. — mrcoffee
Say object #1 and object #2 are seen to be different, but not identified as different. They are both identified as "dog". We know the objects are distinct, be we are identifying them as the same. You might say that this is just a categorization, but for the sake of the logical process which follows the identification, they are the same. So for the sake of the logical process they are said to be the same, when they are really different. — Metaphysician Undercover
The meaning of "less than" is not demonstrated, it is stipulated by definition, in reference to an order. I don't think "less than" can be judged without reference to the definition, and therefore the order. If you want to argue that a definition is an ideal, I don't think you could succeed because definitions are not perfect, due to the ambiguity of words. — Metaphysician Undercover
Right. But in the science of formal systems we discover the relationships of categories/symbols/tokens and not of the marks we need to aid memory and communication. The theorems aren't about the marks. Beyond that, there's no denial that the marks are different. There's just no interest in the mark except as the representation of a category. — mrcoffee
If I draw the letter a in two ways, even a child can agree that the marks are different and yet the 'same' (the same letter). This is an informal computation of the many-to-one function from marks to symbols. Some might prefer to use 'symbols' for what I mean by marks, which is fine. So for clarity I can just talk about the categorization function or categorization itself, which is allowed to place 2 or more different objects in the same conceptual bin. This is just an ability we find ourselves with. Existence is ultimately mysterious, etc. But I don't think there's problem with categorization. A person would have to use categories successfully in order to argue for their failure. — mrcoffee
But surely you didn't mean the usual order on the integers or real numbers? My point is that if something is less than ideal within or about mathematics, that this would tend to involve a notion of the ideal. — mrcoffee
This is not "the science of formal systems", this is philosophy. — Metaphysician Undercover
In philosophy we are concerned with understanding reality as a whole, so we cannot dismiss certain contradictions and inconsistencies as irrelevant to the field of study. — Metaphysician Undercover
If it is necessary that we take two distinct things, which have a very similar physical appearance (two distinct instances of a symbol), and assume that they are "the same", despite the fact that they are clearly not the same, in order to understand some aspect of reality, then as philosophers we ought to recognize and take interest in this, to determine what the implications of such a contradiction might be. — Metaphysician Undercover
Do you recognize the difference between "the ideal", and "the notion of the ideal"? — Metaphysician Undercover
This is why I used zero as the principle for ordering. Let's say someone claims that zero fulfills our notion of the ideal. The argument is that we haven't found any ideal, the category is an empty set, therefore zero is the ideal. However, zero allows for the possibility of ordering toward the negative or the positive, two distinct possibilities. So there is inherent within "zero" two distinct possibilities. Therefore it cannot be the ideal because the ideal must be one unique perfection. The ideal is like the empty set, but it cannot even be represented as zero, because we cannot put zero into that set, because this leaves it not empty. — Metaphysician Undercover
Unless we dismiss them at dead ends or as not really being contradictions. We decide all the time (implicitly at least) what is and is not worth talking about. — mrcoffee
I can't understand what you are trying to say here. Since '0' is just one part of a system (or of many systems), I can't imagine anyone saying that it itself is or is not ideal. I can only guess where you are coming from, but I can say that I found math far less metaphysical upon studying it than I first understood it to be. Or rather it's metaphysical in the driest and most desirable of ways. It works with basic structural intuitions. — mrcoffee
