I insist there IS a backward causal chain. That's empirical and obvious.

I'm showing you it's mathematically impossible that it's an INFINITE backward causal chain.
How interesting. Then you'll have no trouble identifying the first integer with no immediate predecessor.

### Re: Numbers, what are they?

Here's the question: if you do that, then when will you get to write "4"? Right after you write 3. Your argument assumes that which you're trying to prove. You're saying, "There can't be a backward causal chain because ... there can't be a backward causal chain." Even the most casual forum denizen ...

### Re: Numbers, what are they?

But I can do logic very well...certainly well enough to know that if time is linear, as all the actual, empirical, scientific data attests it is, and as our ordinary experience tells us it is, then the universe has a beginning. That's rationally and mathematically inescapable. How does that follow?...

### Re: P=P is a Contradiction

P.S. -- It occurs to me, after the fact, that I may have to point out (or perhaps explain for the first time, if you didn't happen to know already) that "P" in logic stands for either "premise" or "predication." Thus it is not at all the same as a mathematical placeholder like "X" or "Y." It refers...

### Re: Continuum

But recursion is **NOT** late binding. They are grammatically different. I don't recall saying anything to the contrary. But clearly you went out of your way to entirely miss the point of what I was saying to you, just so that you could continue to grind your many axes. It would be better if I stop...

Can only be willful blindness. Or blatant refusal to take responsibility for your own quoted text.

We're done, I'm sure we agree on that. Nice chatting with you.

### Re: P=P is a Contradiction

Well, I am content to mark our disagreement without impugning your character or intelligence. I apologize for my tone. We exchanged a couple of civilities and I should continue to assume this is an honest misunderstanding. I commend you for taking the high road. To keep this simple, please simply r...

### Re: P=P is a Contradiction

That's not what I said. Please read the very sentence above, the one you already quoted, and read carefully. You'll see I say, "Not useless," just "circular" or "obvious." FLT is circular or obvious? You don't know what a tautology is. In logic , a tautology (from Greek: ταυτολογία) is a formula or...

### 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...

Yeah, okay.

Got anything on the actual law of identity?

If not, no thanks.
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.

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...

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.
