Em especial, abordo teses sobre como devem ser compreendidas as proposições categóricas, o que sao precisamente silogismos, o que sao silogismos perfeitos e quais problemas enfrenta a parte da lógica de Aristoteles que lida com proposicoes modais. Nessa direcao, abordo evidencias textuais para duas concepcoes de proposicao categorica e as dificuldades para coaduna-las com as proposicoes singulares. Alem disso, argumento que silogismos devem ser compreendidos como cadeias de predicacoes e que Aristoteles concebe um sistema logico quando procura justificar quais arranjos entre termos formam de fato tais cadeias. Argumento, tambem, que os silogismos perfeitos sao evidentes nesse sistema nao porque considerados indemonstraveis, mas porque podem ser deduzidos a partir de definicoes das proposicoes categoricas e de certas regras gerais, isto e, de regras aplicaveis nao apenas a um tipo de proposicao categorica. Por fim, apresento as caracteristicas gerais e as dificuldades de uma parte da logica de Aristoteles muito pouco associada a logica aristotelica como tradicionalmente entendida: a silogistica modal / Abstract: 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 / Doutorado / Filosofia / Doutor em Filosofia
