## Why still no science of logic?

How does science work? And what's all this about quantum mechanics?

“The Universe has a snese”; is it logical?

Logic is its own science.
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 be accurate and operational.

You might as well ask why no science of science.
Where would be the problem?

What would this thing look like exactly?
Like cognitive science for example. It already exists. The only problem is that it doesn't qualify as a science of logic because cognitive scientists merely assume as correct the definition of logic proposed by mathematicians, even though mathematicians never conducted any scientific investigation of logic (as i defined it in my first post).

I think you are going round in circles of your own design.
You are confusing a study with a methodology.
Try and draw a distinction.

### Re: Why still no science of logic?

I think it is related to there being a lack of con - science whence to derive (!)

For example, if the universe is a toroidal form, mapping a basic torus field would be the first step:

This would "change" how logic is presently handled:
A ≠ A
A = *A
___________
*variable (+) and/or (-) allowing for (e)motion(s)
In such a mapping, any conceivable situation can be reduced into its 'real' and 'imaginary' roots (if/when applicable).

For example, if the universe is "governed" by two "trees", say, √+A and √-A,
(one leading to all suffering/death, the other the absence of suffering/death)
the problem of human suffering can be solved for by assigning operators
"alpha" (ie. all) and "omega" (ie. not) to +A and -A (resp.)
yielding a beginning-to-end 'framework' that solves the root(s) of anything,
including suffering/death.
*A = I am
+A and -A = the alpha and the omega
√+A and √-A the beginning and the end
Humanity still has not developed such a practical science of 'real' logic wherein 'imaginary' is a valid domain.
It is really logical to frame any problem/solution using the same 'framework' the universe is (!)
which invariably contains unreal, imaginary belief-based nonsense(s) invariably causing suffering/death.
However, this presently escapes humanity for their need to cling to such "belief"-based ignorance(s)
for having no conscious knowledge of the same.

Why no science of logic?

By logic, I mean deductive logic.

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 be accurate and operational.

I can't think of any important aspect of the empirical world which is similarly neglected by science.

There doesn't seem to be any practical impossibility.

Cost would not be a significant factor.

Logic seems to be a rather crucial aspect of human intelligence, which is itself at the centre of the very costly drive to produce artificial intelligence systems. The usefulness of an accurate formal model of logic seems therefore beyond question.

So, 2,400 years after Aristotle, why is there still, in the 21st century, no science of logic?

maybe logic-al thinking is an instinct, and so noting more than the other instincts...........aid to survival, but not an related to Truth - whatever that may be.

A humorous interlude.

I am wondering, can sense be made of this at all? A science of logic: Science is known for its rigor, its uncompromising standards that put forth idea only if grounded in observation and the facts of the world. But logic has no factual nature, if you define facts as affairs in the world. Logic is simply tautology made complex, and its rigor is right out there on its sleeve. Analytically true propositions are irrefutable...and vacuous.

The closest anyone ever came was Husserl. See his Ideas, where he identifies the ideational content of empirical concepts. Here, he claims there is a very rigorous "science" that rules the "logic" of thinking in the relations between ideas that are in play when we think about the world. A chair, for example, is, in thought and reason, a body of ideas we associate with a chair, and when science takes up these, it is the ideas in play, not the actuality (sensual intuitions).

You say deductive logic, and it is here Husserl has your point: ideas ARE deductively related, but that gets slippery, for one cannot know fully know the whole of deductive possibilities of a chair, for one cannot know the possibilities, which are infinite and undisclosed. consider: ask, how many facts are there in a given chair? How many centimeters is one of these from the sun? Where is a given chair vis a vis eternity? Just in terms of common facts, there are an infinite number. Quantum physics adds new facts. Tomorrow's physics will add more. And so on.

You would have to clarify your question. Science of logic???

Does this meet your bar? It's even in French.

I'd be interested if we can get a translation of that?

I've sent Girard an e-mail begging him to write it in English...

Until a he (or some other human) gets around to it - use Google's "document translation" https://translate.google.com/?tr=f&hl=e ... auto&tl=en

Much of the content/ideas are an evolutionary progression on his past works on transcendental syntax so the content isn't too hard to follow.

But just to get up to date are we saying that the continental philosophers have taken Anglo-American Analytic Philosophy onboard now and are trying to reinvoke Leibniz's dream?

As an interpretation - it probably hits the mark at 90%.

He's more lucid than that - he is well aware that only language can explain language and acknowledges there's no way around that. But he also heavily critiques Mathematical/analytical reductionism for its model-theoretic incompleteness.

He also seems pretty on-board with the idea that formal languages/syntaxes are just the technology of our day with which knowledge is constructed.
Linear logic happens to be the logic of quantum information - it's the monist metaphysic of physicists. It localized time.

Whatever the next iteration in a scientific paradigm is going to be, it needs a higher order logic than that. It needs 2nd order time.
Higher levels of abstraction allow you to "prove" (express?) more complex interactions.

Godel already told us that Liebnitz' dream is unattainable. Consistency and completeness are opposing goals. Choose one.
Girard chooses completeness. Consistency is an internal property to the system.

His words: "I am not a linear logician."
