P=P is a Contradiction

[raw_thought]

OK, you are claiming that a straight line is not the shortest distance between 2 points! I disagree and so do all mathematicians.

[raw_thought]

This whole debate is silly! I should not have to explain to you that the shortest distance between 2 points is a straight line and that square circles are absurd.

[wtf]

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 be, and often are, surprising, interesting, and deep?

I admire your attempt to provoke. It's not transparent at all...really. Totally fooled me.

No thanks.

I'm not provoking. I'm asking you in all seriousness to either defend or retract your claim that the law of identity is trivial by virtue of its being a tautology. You made the statement. If you're wrong or you misspoke yourself or you phrased your remark carelessly, why not just admit it and clarify yourself? Else you look unserious, like the worst trolls on this site.

[Immanuel Can]

I'm not provoking.

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.

I just live for your good opinion.

If you had read Wittgenstein you would have seen that contradictions are always false. A and not A cannot both be true. Can you give me an example where both A and not A are both true? You are probably confusing truth with validity. here is an argument that is true but invalid. 1. Obama was president.2. Nixon was president. 3. Therefore dogs are mammals. Here is a syllogism that is valid but false. 1. All Martians eat snakes. 2 Bob is a Martian. 3. Therefore Bob eats snakes. Yes, contradictions are invalid. But the result is always false.

I have read Wittgenstein's Philosophical Investigations some years ago...

As to a contradiction being true here is an example:

1. The lemon is yellow.
2. The lemon is not yellow.
3. Therefore the lemon is shades of yellow

Second all contradictions are derived from opposing, or rather disconnected truth values. An example of this would be 2+2=5. Both 2 and 5 exist as rational elements, it is their inability to connect which results in a contradiction.

there is nothing wrong with appealing to authority. For example, every scientific organization in the world supports the proposition that global warming is real and we have facilitated it. Is that 100% proof ? No. But it makes the probability that global warming exists outrageously probable. However, I did not just appeal to authority. I suggested that you read more on the subject.

With Wittgenstien being referenced as an authority to the subject.

You wrote, "Show me a distance between the centre and circumference that is less than 4."
Umm the dot that is diagonal from the center.

The dot that is diagonal from the center is 4 units away from the centrer.

Can you even count?

Wow. You have an immense capability for misunderstanding.

You have it exactly backwards!

The shortest distance between two points is what we call a "straight line".

Is this line the shortest distance between the two points?
Yes it is.

Therefore , in this particular geometry (highlighted, bolded, parenthesised, stressed, accentuated, reiterated, and overly-emphasized) , this line is straight.

Mathematicians agree . You are the odd one out.

Sure if you take perpendicular steps BUT THAT IS NOT A RADIUS! Like I said by your "reasoning" I can say that I am 80,000 miles from New York. All I have to do is go back and forth. Look up radius, by definition it is one continuous straight line.

The blue dot is 2 segments from the other. Draw a STRAIGHT line to connect the two!
