O objetivo deste artigo é analisar os usos que Werner Heisenberg fez da filosofia grega em sua obra. Pretende-se relacionar tais usos não apenas com a argumentação interna presente nos textos do físico alemão, mas também com o contexto histórico, conflitos e debates entre as diversas interpretações da teoria dos quanta durante a primeira metade do século XX. Faremos, inicialmente, uma apresentação geral da teoria quântica e da presença da filosofia na obra de Heisenberg e, em seguida, um estudo de (...) caso da apropriação que Heisenberg fez do pensamento de Leucipo, Demócrito, Heráclito, Platão e Aristóteles.

This article presents arguments and evidence that run counter to the widespread assumption among scholars that humans are intuitive Cartesian substance dualists. With regard to afterlife beliefs, the hypothesis of Cartesian substance dualism as the intuitive folk position fails to have the explanatory power with which its proponents endow it. It is argued that the embedded corollary assumptions of the intuitive Cartesian substance dualist position (that the mind and body are diff erent substances, that the mind and soul are intensionally (...) identical, and that the mind is the sole source of identity) are not compatible with cultural representations such as mythologies, funerary rites, iconography and doctrine as well as empirical evidence concerning intuitive folk reasoning about the mind and body concerning the afterlife. Finally, the article suggests an alternative and more parsimonious explanation for understanding intuitive folk representations of the afterlife. (shrink)

It is usually said that there is a clear difference between pre-philosophical texts such as Homer’s Iliad and what is provided in the fragments corresponding to first philosophers such as Thales of Miletus. This paper tries to show that this is not undoubtedly so, and it does that by means of the analysis of a fragment of the Iliad in which Hypnos is speaking. In this way, the main argument is that, while the fragment can be interpreted both in a (...) literal and in a metaphorical or poetic sense, in both of those cases it can be thought that it is related to philosophy or rational thinking. If the interpretation is literal, the fragment expresses an idea very akin to an important thesis by Thales of Miletus. On the other hand, if the interpretation is metaphorical or poetic, we have to assume, following several contemporary reasoning theories, that the fragment is essentially based on an evident rational inference.
