Are Mentality and Materiality compatible Characteristics?
We have now reduced our original seventeen candidates to the more wieldy number of eleven. Can we make a further reduction? The most promising question to raise at this point is the following. Granted that mentality and materiality are distinct and mutually irreducible characteristics, could any substance or event possess both of them? If we could answer this in the negative, if we could show that it is as absurd to suppose that the same event or substance could be both mental and material as to suppose that the same material substance could be at once red and blue all over, we could make a considerable clearance.
