RESUMO

The present dissertation discusses aspects of Aristotle s Logic which are enhanced by contemporary approaches to Prior Analytics and display a logical theory richer and subtler than what traditionally is comprehended as being the Aristotelian Logic. My main claims concern how categorical propositions must be understood, what is the exact nature of syllogisms, what is a perfect syllogism, as well as some questions in the part of Aristotelian Logic which deals with modal propositions. From an examination of texts that support two different conceptions of categorical proposition, I discuss the difficulties in adjusting each of them to singular propositions. I also argue that syllogisms must be comprehended as chains of predications and that Aristotle conceives a logical system when he proceeds to justify which terms arrangement does produce chains of the required kind. I also argue that in this system perfect syllogisms must be understood as evident not because they are unproved, but because they are deduced from definitions for categorical propositions and from general rules, i.e. rules not applied just to some categorical propositions. Finally, I discuss general features and problems concerning a part of Aristotle s Logic rarely attached to the Aristotelian Logic as traditionally comprehended: the modal syllogistic.
