Background: I want to study philosophy and I think a good way is to first learn logic, so I tried reading The Categories. But even after trying so hard, I didn't understand it. The writing is very obscure, not enough examples and Aristotle changes his topic faster than the speed of light. So I thought I should read commentaries on Categories, I chose Simplicius' commentary, and I didn't understand most of it.
Question: What references are available to teach Aristotelian logic in its historical form?
Clarification: So I would like a list of references that teach Aristotelian logic. Please note I don't want to learn formal logic, and I am not asking for commentaries on Aristotelian logic; I already have many. The book I am asking for should teach Aristotelian logic specifically; all or most of the topics mentioned in The Organon and the contents of the book must overlap strongly with the Organon.
