Did any intellectual luminary ever articualted any major disagreement with Aristotle's logic prior to the inception of modern mathematical "classical" logic?
Which rational thinkers, such as scholastic theologians, philosophers, scientists, mathematicians etc. prior to 1850 formally articulated any substantial disagreement with Aristotle's theory of logic, as it is implicitly contained in and expressed by his syllogistic?
On the subject of logical implication and validity, I see Fregean logic to be in formal contradiction to Aristotle's syllogistic. As I understand it, all of mathematical "classical", i.e. two-valued, logic, including modal logic, subsequently adopted, through Russell's so-called "material" implication, the Fregean paradigm and, therefore, seems itself in formal contradiction with Aristotle.
However, prior to the inception of Frege's formal logic, I'm not aware that any intellectual luminary in the past ever articulated any substantial critique, and even less refutation, of Aristotle's...
