I'm looking for a serious and popular science forum website...
I just tried Physics Forum (https://www.physicsforums.com/) but they banned me after only three posts for allegedly breaking some rule.
Reason given: "no defined end of debate"!
You may be able to look at the posts to see for yourself how justified that may have been.
As far as I can see, one of the ayatollahs there had a breakdown upon seeing me using the word "usefulness" in relation to formal logic. According to this very bright individual, asking about the usefulness of logic is to irredeemably cross the line into philosophy territory, a definite no-no over there.
So, I'm looking for an alternative...
Thanks,
EB

What exactly is the usefulness of formal logic theory?
And how much useful is it?
I believe that most of us have an intuitive sense of logic, which has to be very useful throughout our lives and just about for every situation we can think of. Given that, I came to wonder what more does formal logic specifically brings to the table?
Obviously, having a formal language to express the more complicated logical relations is very useful, even necessary nowadays with the development of technology and science, but beyond instances of using the formalism of formal logic, could anybody give practical examples of using formal logic theory to solve a problem in the real world? Something useful!
And I would exclude from that maths research, not because I think it's hopelessly useless, but because I need to understand how logic theory is useful and I need to understand that here and now. So, using logic theory to help with applied maths would be OK, too. That is, if logic theory is used to sort out a maths problem meant to model some real-world situation, in which case logic theory would be useful to help with useful maths, and that would be obviously useful.
I'm really only interested in First Order Logic, but Second Order examples should also be of interest.

I have severe problems with what you call useful. This is a short sighted and highly subjective term which hasn't any scientific relevance. Take the zero, e.g. Why did people start to count something, which isn't there? That's why I consider the word useful as a biased, purely rhetoric term without any substance, except to start a fruitless dispute. What you call useful logic, is merely one possible logic system. The usefulness of all other, and there are various, is restricted by our current limitation, not by the number of potential alternatives. But even the predicate logic in use appears quite often rather alienated, esp. in interviews of politicians.
So logic is important, because it measures scientific fields and helps to distinguish between valid and absurd theories. Same as the meter is.
This discussion is already philosophy, because it basically asks about the usefulness of science - logic is just a placeholder here. A sujet, which has been discussed before, on PF as well, please make a forums search, and probably will be discussed on many other occasions and places. There is no final answer to this by the setting of the question, and any answer heavily depends on personal scales.
So if you don't have a specific source from a valid scientific publication, in which case you're invited to send me a PM with a reference, this thread is closed. Reason: no defined end of debate.
And my introduction:

Hi everybody!
I'm French and live in the Macronian world of Paris. I'm a bit retired to be honest but I'm actually trying to do something useful. And, usefulness will indeed be the point of my first (real) post here. So, watch out!
Like all of you, I'm essentially interested in life, but I also spend time thinking about 'philosophical' issues, like the hard problem of consciousness (hey, I can hear you cringe, you know!) , and also about logic. I did two years in maths and physics at the university here in Paris, which was unfortunately a very long time ago, and I had a class on logic at the time. Well, I got interested there and then. For the rest of my life! So, going into retirement, I thought I would revisit the subject. So, I'm working on that, if 'working' is at all the right term for what I'm doing. I may have a few posts on other sciency things but, essentially, it should be about logic. And, yes, usefulness.
After two years, I had to give up on the idea of becoming a scientist. Too bad, that. So, I'm not going to pretend I have any expertise on any scientific issue. I try to keep an eye on what you guys are doing but it's gone way beyond the layman's ability to keep up and understand, this stuff. And maybe I'll have a few posts on that as well.
Ah, I almost forgot. Why a Descartes avatar? Very simple. I take the Cogito to be a beautifully apt expression of the only thing I know. I even wonder how René could have guessed that about me! So, all the rest, I can only believe.
Still, I'm not here to discuss what I do or don't know, so you should all be safe from that at least.
Well, that will be all for now, folks. See you 'round here!
