¿Es el argumento del conocimiento de Jackson un knock‐out al fisicalismo reductivo?

Abstract

This article seeks to answer the question of whether the knowledge argument raised by Frank Jackson, in the cases of Mary and Fred, manages to be a devastating criticism about reductivist physicalism. The aim of Jackson's knowledge argument was to prove the insufficiency of reductivist physicalism to explain reality, as well as to demonstrate the existence of epiphenomenal qualia (non‐physical and impotent elements causally). My answer to the question is negative, since I consider that reductivist physicalism manages to overcome the problem posed by Jackson using himself and, on the other hand, I consider that epiphenomenal qualia does have a certain causal role.
