A obra filosófica de Cícero põe em cena debates intelectuais entre membros da elite romana, e suas figuras principais exibem uma combinação equilibrada de dotes intelectuais, excelência moral e expertise política. A filosofia grega emerge como um importante aliado no projeto intelectual de Cícero, mas não in toto. Este artigo lida com o modo pelo qual Cícero denigre uma multitudo de filósofos que produziam aquilo que ele considerava obras moralmente perigosas e estilisticamente inferiores, contribuindo para a criação de uma filosofia (...) “clássica” que ainda configura o estudo moderno da filosofia.

This paper analyzes the apraxia argument in Cicero’s Academica. It proposes that the argument assumes two modes: the evidential mode maintains that skepticism is false, while the pragmatic claims that it is disadvantageous. The paper then develops a tension between the two modes, and concludes by exploring some differences between ancient and contemporary skepticism.

The Renaissance sceptic and medical doctor Francisco Sanchez has been rather unduly neglected in scholarly work on Renaissance scepticism. In this paper I discuss his scepticism against the background of the ancient distinction between Academic and Pyrrhonian scepticism. I argue that Sanchez was a Pyrrhonist rather than, as has been claimed in recent years, a mitigated Academic sceptic. In keeping with this I shall also try to show that Sanchez was crucially influenced by the ancient medical school of empiricism, a (...) school closely allied with Pyrrhonism. (shrink)

Brutus’ De virtute, a lost work that had important but overlooked influence on Cicero’s ethical dialogues, is more dependent on Antiochus’ ethics than has been recognized. In reviewing the sources for De virtute, I arrive at a conception of Brutus’ work as a consolation written in a fundamentalist—rather than ecumenical—mode that focalizes its arguments and commonplaces from the perspective of Antiochus’ philosophical system. This conception is supported by the only other testimony for Brutus’ consolatory writing.

The present paper focuses on some aspects of the Neoplatonist literary-metaphysical theory, which has clearly been expressed in the anony­mous Prolegomena to Plato’s philosophy and further confirmed in Proclus’ exegesis of the Timaeus. Thus, this contribution, examines and compares several passages from the Prolegomena and from Proclus’ Commentary on the Timaeus with a view to showing that it is legiti­mate to speak of a certain cosmogony of the Platonic dialogue that is analogous to that of the macrocosm. Moreover, the analogy (...) between macrocosm and microcosm makes it possible to further investigate the similarity between the λόγος-ζῷον of the Demiurge and that of Timaeus, on the one hand, and the reality which the λόγος expresses, on the other. This similarity turns out to be both structural/morphological and content-related/semantic. Thus, by combining the natural and theo­logical science, the analysis of the “generation” of the macrocosm and microcosm brings out the strongly analogical nature of Plato’s dialogues, which is particularly visible in the Timaeus.
