The physicalist response to the knowledge argument first is that it assumes the conclusion within its premises. The idea that all the physical information is given to her makes the a priori assumption that all the physical information that could ever be given will not suffice to her understanding the qualia of seeing red. Furthermore, when she steps outside the room and experiences seeing red she is having a physical experience where her senses are activated from perceiving the color. Therefore, she did not have the physical experience and consequently not all the physical information. In addition, Frank Jackson replied to his own argument years later, explaining problems he found within his article. In his “Postscript On Qualia”, he gave two reasons for changing his mind: one, that you could have a false memory trace, or misremember something causing you to have a false idea of what the color red is, and two, that causal origins must not outrun the effects. His first reason explains that we could appear to have the qualia of seeing red yet not have the real qualia through a false perception of what seeing red is. His second reason states that because the causes of mental states are physical the effect must be physical as well. In consequent of these issues, the famous Knowledge Argument fails to prove that qualia is fundamentally …show more content…
As presented, many famous dualist arguments argue from ignorance, contain circular reasoning, or fall on the misguided path of applying logical possibility as metaphysical possibility. When acknowledging these issues of dualism, physicalism remains on the table as a more suitable path of thought. While physicalism does not yet deliver a conclusive solution to the question of the nature of the mind in relation to the physical body, it is an evolving theory that continues to make advancements throughout history. While dualism is doomed by the fundamental mistakes in its key arguments, physicalism has made great strides in understanding the mind through neuroscience, and eventually one day may be able to answer the question of the mind/body
