### Re: P=P is a Contradiction

But my real interest in doing so was to speak about the law of identity, which is a truth without which no mathematics would be possible. So I'm sure you can get behind the law of identity. Fair enough? Yes and no but mostly no. First, I don't actually have much interest in the subject. I agree wit...

### Re: Continuum

I agree with you that thoughts are real. Just using this random quote so your handle will be tagged. I think I had an insight and can sum things up. When I typed in the Python program def f() : f() I realized that what you are talking about by self-reference or "nondeterministic functions" are what...

### Re: P=P is a Contradiction

I just live for your good opinion. I do wonder why you can't answer a simple question. You seemed to imply that tautologies add no new information. If I misunderstood your intent, just tell me that . Why are you playing games instead? If you meant to say what you seemed to, you're wrong; because ta...

### Re: Continuum

If you think Mathematical operators are nouns we have some deep-seated misunderstanding. f(x) -> x The only noun here is the unbound variable. "A function is a mapping from one set to another." Please identify the subject of that sentence and confirm whether you think it's a noun or not. I honestly...

### Re: P=P is a Contradiction

You do fine arguing with the cranks. But when someone who knows what they're talking about calls you on a false statement, you run away. Pathetic.Immanuel Can wrote: ↑Fri Sep 18, 2020 12:14 amYeah, okay.

Got anything on the actual law of identity?

If not, no thanks.

### Re: P=P is a Contradiction

You spoke nonsense and asserted it as truth. How could anyone take you seriously? I admire your attempt to provoke. It's not transparent at all...really. Totally fooled me. I'm not provoking. I'm asking you in all seriousness to either defend or retract your claim that the law of identity is trivia...

### Re: P=P is a Contradiction

That's too bad. I'm not interested in the side road that interests you. Feel free to hold forth on it as you like...I'm working on the law of identity, and nothing else. You spoke nonsense and asserted it as truth. How could anyone take you seriously? Do you or don't you agree that tautologies can ...

### Re: P=P is a Contradiction

You didn't even read the thread. I agree that I'm not following the thread. I'm only commenting on this completely false statement that you made: "P=P is also a tautology. The fault is not that it is wrong, or tells a lie; it's that even if true, it's utterly uninformative of anything new. It adds ...

### Re: P=P is a Contradiction

We're talking about the law of identity . For that, the mathematics don't even matter. They're an analogy, not a literal demonstration. Logic symbols are not mathematical symbols. Hope that clears that up. Not even remotely. I linked the Wiki page defining the word tautology. The fact is that most ...

### Re: P=P is a Contradiction

P=P is also a tautology. The fault is not that it is wrong , or tells a lie ; it's that even if true, it's utterly uninformative of anything new. It adds no value to our thinking at all. In the mathematical theory of rings (which includes the integers, rationals, real, and complex number systems), ...

### Re: Beyond the Law of Noncontradiction

Why bother. Whatever it says, it's opposite is also true. If you believe that nonsense, I'll take your word for it. I read the article twenty year ago. You won't read it and you already did read it. P and not-P. My point exactly. Thank you for so perfectly demonstrating the utility of constrained i...

### Re: Continuum

Concrete rocks are instances (of information). The abstract concept of a rock is a pattern (of information). The word "rock" itself is a representation (of information). It represents either an instance or a pattern (of information). Ok. Yes, but words can represent (point to?) concrete or abstract...
