PHLA10 Reason and Truth
1. What is the difference between dualism and materialism?
The difference lies on whether they think mind and matter
are different things or not. Dualism says mind and matter
are different things while materialism believes mind is a
part of the material world.
2. What is Leibniz's Law? What is it good for?
Leibniz’s Law says if two objects X and Y are identical,
then properties of X must be properties of Y, and vice versa.
It indicates that X having a property that Y lacks can imply
that X is not Y. This law is good for arguments that try to
identify if two objects are the same thing.
3. Explain what is wrong (according to Sober) with the first
Cartesian argument for dualism.
Sober thinks dualism doesn’t follow the premises the first
Cartesian argument gives. He argues that indubitable
existence is not a property. When you try to say that A doubts
or cannot doubt B, this is a property of A instead of B. 4. What is the second Cartesian argument for dualism?
The body has spatial properties
The mind has no spatial properties
