Resumen de Strong Emergence as a Defese of Non-Reductive Physicalism
Jaegwon Kim, and others, have recently posed a powerful challenge to both emergentism and non-reductive physicalism by providing arguments that these positons are committed to an untenabie combination of both 'upward' and 'dounward' determination. In section 1, I illuminate how the nature of the realization relation underlies such skeptical arguments However, in section 2, I suggest that such conclusions involve a confusion between the implications of physicalism and those of a related thesis in 'Completeness of Physics' (CoP). I show tht the truth of CoP poses a very serious obstacle to realized properties being efficacious in a physicalist universe and suggest that abandoning CoP offers hope for defending non-reductive physicalism. I then fornulate a schema for a physicalist metaphysics, in section 3, which rejects CoP. This scenario is one where microphysical properties have a few conditional powers that they contribute to individuals when they realize certain properties. In such a situation, I argue, though physicalism holds true there is still plausibly both `upward' and 'downward' determination, where the latter is crucially an underappreciated form of determmation I term 'non- causal'. Ultimately, I conclude that this metaphysical schema offers a coherent account of Strongly ernergent properties that preserves the truth of NRP, albeit in a form that is purged of any committment to CoP. Finally, in section 4, I carefully explore which of Kim's assumptions and arguments this metaphysics undermines.
