Summarize Frank
Jackson’s article, “Epiphenomenal Qualia,”
Jackson talks about how his “Knowledge argument” proves that
Physicalism is false and compare the “Knowledge argument” with the Modal and
“What is it like to be” argument to find the argument with the “greatest
polemical utility.”
In his “Knowledge argument”, he gives an example of Fred
being able to see colours that nobody else can. He states that even if we know
all every physical nature of Fred, it does not mean we know everything about
Fred. This shows that Physicalism is incomplete.
The example for the Modal argument is an alternate world
with humans without conscious mental life. Everything physically is the same
yet there is something more in us than just purely physical. Hence, Physicalism
is false. The problem of the Modal argument is that it rest on a disputable
modal intuition. And not everybody agree with the intuition after thinking
about it again. Hence, “Knowledge argument” is better.
The “What is it like to be X” argument shows that we cannot
imagine what it is like to be X regardless of the amount of physical
information we have. However, it is not a problem for Physicalism as it does
not claim that such extrapolation is possible.
