Re: Why still no science of logic?

Logic is its own science. You clearly didn't read my first post. Read again, more carefully: By science of logic, I mean a scientific investigation of logic as objective performance and manifest capability of human beings, investigation that would try to develop a formal model of logic which would ...

Re: Your brain tricks you into believing... What?!

One example, and perhaps the most convincing example, of psychologists, including neuroscientists, actually concluding from their research that a standard mental event is best understood as, literally, an illusion that people have is the frequent scientific conclusion that our belief that we have f...

Re: Your brain tricks you into believing... What?!

The argument is that you don't freely choose your 'wants'. They are completely the result of "purely physical (as opposed to metaphysical) causes and prior states of the world". You have no choice in what you want. Therefore thinking that you are doing what you want is part of the illusion. But thi...

Re: The Nature of Consciousness

Perhaps I misunderstood. I thought, in your sentence, "I don't need to be given an explanation of reality because by definition there is none ," your phrase, "because by definition there is none," modified the noun, "reality," immediately preceding it. You apparently meant for it to modify the enti...

Counter-intuitive formulas?

Are there propositional logic formulas, outside self-referential ones, whose validity or invalidity is often perceived as counter-intuitive?

Re: The Nature of Consciousness

Existence is indeed fundamental but existence only as you experience it subjectively, and as such it implies neither space, time nor space-time just as the quale of redness doesn't imply anything about the physical world. Existence in space-time, or more generally in the physical world, or indeed e...

Re: The Nature of Consciousness

... I don't need to be given an explanation of reality because by definition there is none. But explain to me what is really the physical world. At first blush, the request seems disingenuous. If you know there is no reality (by definition) what would be the point of asking for an explanation of wh...

Re: The Nature of Consciousness

I'd start with the idea of existence, which you seem to take as fundamental. If so, then it would seem to follow that space-time is fundamental. This idea doesn't fly. Existence is indeed fundamental but existence only as you experience it subjectively, and as such it implies neither space, time no...

Re: The Nature of Consciousness

The "Consciousness-Physical" Problem There is a supposed problem in philosophy, more often called the "mind-body" problem, that asks, "if the mind (or consciousness) is not physical, how does the non-physical interact with or control the physical body. The question pertains to all conscious organis...

Re: Eliminating Undecidability and Incompleteness in Formal Systems

The trivial counter-example is the married bachelor of sciences. LOL. Good one! But then again I don't believe natural language can be axiomatized. PeteOlcott does, if I understand him correctly. ps -- How about this guy? http://johnbatchelorshow.com/ How critical is the exact spelling of a word? T...

Re: Rationalism v. empiricism

But can an internal observation be objective? I think not. There can be no consensus about an observation that is limited to one observer, and an internal observation at that. Sure, but that's still an observation of reality. And again, objectivity doesn't guaranty truth. Historically, it is always...

Re: Rationalism v. empiricism

Can we say that introspection is a form of observation? I think it clearly is. It is obviously a different modality but that is definitely how humanity has always thought of it. Personally, I think it's a good idea to pay attention to your own state of mind, without making too much of it. And of co...
