According to Aristotle, phainomena or “appearances” provide the basis from which researches proceed. This shows that in spite of phainomena often corresponding to what falsely appears to be the case, there is genuine cognition through them. In this paper, I focus on two features of phainomenal cognition: accessibility and epistemological limitation. A phainomenal cognition of x is limited in the sense that there is always a stronger cognition of x to be attained. In this way, a research always aims at (...) surpassing the phainomenal cognition of its subject matter. On the other hand, phainomenal cognition is always somehow accessible. Resorting to the relation between phainomena and the distinction between the more intelligible to us and the more intelligible by nature, I intend to put forward a relative (as opposed to an absolute) understanding of both accessibility and epistemological limitation of phainomena.

I discuss the exact meaning of the thesis according to which the object of scientific knowledge is necessary. The thesis is expressed by Aristotle in the Posterior Analytics, in his definition of scientific knowledge. The traditional interpretation understands this definition as depending on two parallel and independent requirements, the causality requirement and the necessity requirement. Against this interpretation, I try to show, through the examination of several passages that refer to the definition of scientific knowledge, that the necessity requirement specifies (...) more exactly the causality requirement: what cannot be otherwise is the explanatory relation between the explanandum and the cause by which it is what it is.

according to aristotle's posterior analytics, scientific expertise is composed of two different cognitive dispositions. Some propositions in the domain can be scientifically explained, which means that they are known by "demonstration", a deductive argument in which the premises are explanatory of the conclusion. Thus, the kind of cognition that apprehends those propositions is called "demonstrative knowledge".1 However, not all propositions in a scientific domain are demonstrable. Demonstrations are ultimately based on indemonstrable principles, whose knowledge is called "comprehension".2 If the knowledge (...) of all scientific propositions were... (shrink)

A presente pesquisa visa caracterizar o método empregado por Aristóteles na Ethica Nicomachea a partir de uma análise que contrasta duas interpretações: de um lado, a tese já tradicional que busca ver na filosofia prática do Estagirita um método estritamente dialético; de outro, a tese alternativa, explorada apenas recentemente, que aponta o uso, na EN, de um procedimento filosófico próximo das prescrições sugeridas nos Segundos Analíticos para a busca definicional nas ciências. O núcleo da primeira tese deverá ser analisado sob (...) duas perspectivas: (i) examinando um conjunto de textos que revelam o teor dialético da filosofia aristotélica; e (ii) avaliando o processo de expansão da noção de dialética e suas implicações para os estudos aristotélicos. Alternativamente, (i) será examinado como um modelo de tipo definicional pode reaproximar a ética do registro científico dos Segundos Analíticos sem necessariamente se valer de argumentos dialéticos. Por fim (ii), proponho uma versão deflacionária do que deve contar como método dialético em Aristóteles. (shrink)
