Resumo
Nesta Dissertação, abordamos a proposta do monismo dual (ou de duplo aspecto), sugerida por Thomas Nagel, para analisar os aspectos do mental como a consciência e os qualia. O estudo propõe analisar em que medida essas características mentais podem ser descritas de forma física, ou se, ao efetuar uma análise minunciosa dessas características, podemos concluir que elas não podem ser descritas da mesma forma que descrevemos eventos físicos. Para que possamos, então, as analisar, descrevemos, inicialmente, a abordagem dualista e em que medida ela contribui para nossa compreensão das características mentais como eventos não físicos. Analisamos, também seus problemas e dificuldades em se explicar a interação de processos mentais não físicos com o corpo físico. Em seguida, abordamos a concepção fisicalista, na qual, propomos descrever seus problemas e as razões pelas quais as características mentais não podem ser, simplesmente, explicadas ou mesmo descritas como processos físicos ordinários. No capítulo seguinte, descrevemos a perspectiva de Nagel, sobre a proposta do monismo de duplo aspecto, no qual o autor propõe duas perspectivas epistemológicas sobre a mente consciente, as perspectivas de primeira pessoa, restrita ao próprio ser consciente, e a perspectiva de terceira pessoa, correspondendo ao modo de abordagem típico das ciências empíricas. Nesta abordagem, as qualidades subjetivas (qualia) se restringem à perspectiva de primeira pessoa. Portanto, o monismo de duplo aspecto em Nagel pode ser caracterizado como sendo ontologicamente monista (trata-se de um só ser consciente) e epistemologicamente dualista (este ser é apreendido por si mesmo na perspectiva de primeira pessoa, e abordado cientificamente na perspectiva da terceira pessoa).
We approach the proposal of dual-aspect monism by Thomas Nagel to analyze the conscious mind and related concepts as qualia. To what extent these mental characteristics can be described in a physical way, or, by performing a thorough analysis of these characteristics, should we conclude that they cannot be described in the same way that we describe physical events? We first describe the dualistic approach and to what extent it contributes to our understanding of the mental characteristics as non-physical events. We also analyze the problems and difficulties in explaining the interaction of non-physical mental processes with the physical body. Then we approach the physicalist conception and propose to describe its problems and the reasons why the mental characteristics cannot be simply explained or even described as ordinary physical processes. In the following chapter, we describe Nagel's perspective on the proposition of dual-aspect monism, in which the author proposes two epistemological perspectives on the conscious mind, the first person perspective, restricted to the conscious being itself, and the third person perspective, corresponding to the typical approach of the empirical sciences. In his view, subjective qualities (qualia) are restricted to the first-person perspective. Therefore, dual-aspect monism in Nagel can be characterized as being ontologically monistic (we are one being, body and mind) and epistemologically dualistic (this being is apprehended by herself in the first-person perspective, and approached scientifically from the third person perspective).
