please, not again!As pointed out before, you aren't forced to read anything.
As pointed out before, you aren't forced to read anything.but are you being forced to post?
but are you being forced to post?No, and I've explained this to you before. I post things I find intetesting, I make an effort to do so because if there aren't new topics the forum will wither and die, and as a mod I am trying to avoid that.
It's very wordy, reviews some history but does not really answer the question posed.
Looking at the history of logic and its interaction with other influences

Logic to me is " what reasonably follows on from"
So people years ago made what they saw as logical ideas, with the knowledge they had at the time.
Nowadays with modern science as we know it, their ideas don't look so logical.
One day, as science progresses maybe our own ideas won't look as logical as we think they are 🙂
IMO the history of logic is tied in with knowledge possessed at the time.
Yes...I agree. Logic is not fixed in stone. It changes with time, knowledge, circumstances and so on. All logic is not mathematics.
What may seem reasonable and logical with a certain perception could seem completely unreasonable and illogical with a different perception. It could also depend on ones background, culture and social environment.

The area of a circle was always related to the square of its radius by a factor of 3 and a bit long before Pythagoras figured it out.

Logic is related to culture, background and whatever seems reasonable at that time, in that social culture, with that knowledge and in that situation.
For example....in a culture which is largely religious...it would be very logical to suppose that a God created the world. Logically there is no other explanation at all. To argue that the universe got generated by chance...would be very illogical and unreasonable.
In an atheist culture it would be logical to assume that some natural law generated the universe.

No, and I've explained this to you before. I post things I find intetesting, I make an effort to do so because if there aren't new topics the forum will wither and die, and as a mod I am trying to avoid that.here's a tip for you . If your aim is to keep this forum alive why not post something the majority might find interesting rather than your own pet subject.
That is wrong.
You continue to mistake comprehension for logic. The area of a circle was always related to the square of its radius by a factor of 3 and a bit long before Pythagoras figured it out. Logic expresses truths and truths do not vary based on the cognitive ability of bipedal African apes to comprehend them.
torridon......
Logic is NOT mathematics..repeat NOT mathematics! 2+2=-4 is only one specific type of logic that seems to be valid for all time (In fact, I am not even sure if maths is valid for all time and all space...but that's a different argument!)
Logic is about reasonableness. (Check out the dictionary definitions). It is time, knowledge and culture (belief, lifestyle) dependent.
As I have said...'God created the world' is perfectly logical. 'The sun goes around the earth' is perfectly logical. And so many other such normal phenomena for which we today have different explanations.
1000 years from today everything that seems perfectly logical to us today may seem nonsensical to those people.
Some people tend to hijack words like logic, energy, science etc. and confine their usage to very narrow domains. This robs them of their larger and wider meanings. And then they keep arguing about words and semantics.

It looks to me as though you like the sound of your own typing ;)
Oh dear, you are just sticking to your very superficial understanding of the concept of logic. There is a difference between what might seem logical at any point in time and what actually is logical, but that is not because logic varies, it is simply because our comprehension has altered. Logic itself is abstract and self referential and not dependent on any context, such as human culture. If it were then we this would manifest most immediately in maths and international trade would not be viable if numbers added up differently from country to country. Not that maths is the only form of logic, it is merely the manifestation of logic that is easiest to exemplify in discussion. I think you didn't bother to read the Wiki page on logic you posted up; there is nothing in there to support your claims.
There is nothing called 'actually logical'. Nothing is ACTUALLY logical....for heavens sake.
Logic is not about facts...
...or mathematical accuracy...
...it is about what seems reasonable.
Even facts can seem illogical. We live on a globe flying around the sun at several hundred kms per hour. That would seem illogical but is still a fact.
You may think that people of earlier times were ignorant and our knowledge of today is something of a supreme kind and therefore our LOGIC of today based on scientific knowledge is irrefutable. Wrong! What we consider logical today could seem illogical and even stupid just 100 years from today.

If you want to debate whether he posts stuff because he likes the sound of his typing, why don't you raise the topic.
