Here is the OP again for those who might be interested:
Here is your chance to air your views as to whence comes logic.
As a motivation introduction, I observe that most educated people take logic to be a branch of mathematics, or perhaps whatever mathematicians study that they call "logic" since broadly the beginning of the 20th century. Yet, the first systematic presentation of what humans understand of logical rules was made by Aristotle and that was something like 2,400 years ago, and as far as I know, most intellectuals since have accepted Aristotle's presentation as correct. I'm not aware that anything in mathematical logic shows Aristotle was wrong.
Whatever the case, is it possible to study anything if there isn't something to study? This suggests logic exists somehow somewhere. But where exactly?
Traditionally, philosophers see rules of logic as necessary and a priori, rather than contingent and empirical. Putnam argued they could be empirical, taking the example of Quantum Physics to support this suggestion. Yet, even a priori rules have to come from somewhere unless you think God the merciful help us sort out the necessary from the contingent.
If we all have our own personal sense of logic, why is it most intellectuals agreed with Aristotle's logic (and I would assume most people here)? But if we all have the same logic, how come?
And where are we supposed to look when we want to produce a method of logic that, somehow, would be correct?
