A Realist

My guess is that NP vs P will be proven undecidable. But who really knows?

One opts that not even God knows what my next question would be? So if the universal mind cannot have perfect knowledge, we as mere mortals cannot pos...

My own belief is that the universe never actually started in the BB... as the song goes there's no beginning and there's no ending...

So what is that: "The knowledge you are seeking lies beyond sensory data, trustworthy or not."?

Beyond sensory data, are you alluding to 'faith' here?

well you know my hallucinations might tell me something about reality... who knows. :-) https://www.youtube.com/watch?v=zE7PKRjrid4 BTW, I took both t...

Well, why not to dare to question my senses if I may hallucinate something etc then my senses can be fooled. If my senses can be fooled then how can I...

Don't know. There are all sorts of logics out there.

The problem with higher than first order logic, is that they don't have a complete proof theory. https://en.wikipedia.org/wiki/Second-order_logic (und...

In the logic you are using can we use modus ponens as an inference rule?

As Einstein once said "everything is relative". I believe in everything and in nothing. There was once a poster called grady from physicsforums who in...

That's it, I don't know what is a "sane person".

Define to me "sane person".

I know. You gotta love Logic!

A classical song: https://www.youtube.com/watch?v=dSbKNkPlrxk&ab_channel=fallenleaf25

The existence of God.

something can be real to me but not real to someone else. That's what I am getting at.

Reality is what you believe to be real, in short.

Let's see if I can't depend on my senses to gather what is real then I left with my mind. https://www.youtube.com/watch?v=WM8bTdBs-cw&ab_channel=Metal...

You,I,me,him,her, everybody needs some recognition cause being all alone is quite a freitening thought to bear. But eventually all our are dear loved ...

And when I think about it, now I just might be talking to myself... :-D

When you think about it really. In philosophy there are only questions and no answers. As opposed to maths,physics,engineering and logic where there s...

Quite hilarious, ain't it?!

Don't be so humble, you are a genius!

You didn't but I did. so yes you did.

If you want to write it in Doxastic Logic's notation then it's: from Bp being true you can entail that p is true.

The Socrates theme was a reply to Banno's DisneyLand YT film. Anyways, the Liar paradox can also be regarded as both true and false. As long as you or...

It doesn't matter if it's true for others, as long as you or I or him believe it to be true. Besides of course tautologies and contradictions, and sta...

Something is true, if you believe it to be true. Obviously Av~A is true and A&~A is false. Other statments are contingents, as in are not a tautology ...

Well, you need ro assume something, don't you? Unless you want to assume the empty assumption of not assuming anything... :-) In which case you cannot...

In what type of Logic do you want your proof to be served to you?

Like our conversation. Reality is habitual hallucination, whatever that means... :-)

Does Jack think the bartender is real or not? You are contradicting yourself.

So he's not real, because he doesn't believe the bartender is real.

How do you know?

Then he's real.

Real is what you believe to be real.

Another book which should be on every logician shelfs is Logic of provability by George Boolos. I started reading it years ago, I believe this should ...

I am not sure this is addressed in those books. But are you acquainted with peter smith's book and Smullyan's books?

First cause is not a logical necessity. Existence is either way paradoxical. You can find a system where it's necessary and a system where it's not ne...

Well the question is what constitutes for "impossible" and what constitutes for "omnipotent"? Can an omnipotent being (if existed) be both dead and al...

It's not quite the same. The coin is in a superposition of both before you collapse the wave function of the coin by taking a look at the coin. If no ...

Can Schrodinger's cat be both dead and alive before I measure? Doesn't it constitute as a true contradiction?

Give it time, eventually an infinite number of monkeys will do that (i.e there exists N\in \mathbb{N} s.t for all n>N, n number of monkeys will succee...

Nature.

You can answer my question for starters, does the pocket contain itself? does the universe contain itself? I think that indeed it does. U \subset U \s...

Does the pocket contain itself? :-) https://www.youtube.com/watch?v=v2AC41dglnM

There is always something... That's the magic of existence. https://www.youtube.com/watch?v=0p_1QSUsbsM
