A Simple Argument against Dualism
You asked what was the problem for dualism.
I answered.
The problem for dualism is to account for how the non-physical acts upon the physical causally.
The monist does not have this issue because they do not maintain that the non-physical acts upon the physical causally.
What do you mean by asking why it should? — Michael
I mean just what I wrote, why should the non-physical be such that it is causal but not physical?
Because unless the physical is defined as being whatever has causal influence on the physical (a circular and so vacuous definition) then having causal influence on the physical doesn't make you physical (at least not by definition). — Michael
It is not circular or vacuous it is economical.
There is less to account for, if the mind is physical, then that is what accounts for physical causation.
There is no need to multiply explanations beyond monism.
Maybe not if you only consider the interaction problem. But there are other concerns that dualists will claim warrant regarding the mind as non-physical. — Michael
How is dualism necessary?
Are you proposing that monism necessarily false?
