Both of the following arguments are valid in classical logic. Symbolize them and then explain why they are valid.

Logic and Philosophy (add the true table)

1- Both of the following arguments are valid in classical logic. Symbolize them and then explain why they are valid.

a- The mind is both physical and also not physical. It follows from this that the mind is a non-alcoholic beverage.

b- Either the mind is not physical or the mind is a non-alcoholic beverage but the mind is indeed physical, so it must be the case that the mind is a non-alcoholic beverage.

2- Both of the previous arguments are invalid in a non-classical system that allows that there can be true contradictions (like “this sentence is false” and Russell’s paradoxes). Explain how this is the case.
