PHIL 2160 Lecture Notes - Lecture 18: Mind, Subjective Idealism, Hylas
Document Summary
Main arguments for: qualities in the mind, idea of existence, his immaterialism, resemblance (likeness principle) We can"t think of bodies without thinking of them in terms of their primary qualities, for locke. There are material things that exist outside of our mind. Primary qualities are qualities bodies really have, and they are representational of the world. Secondary qualities are caused by the primary qualities, but they are relative, and whatever is outside the mind does not identically resemble what is in the mind. If we say something exists ( it exists ), we mean we perceive it it must be a perceivable thing, by at least one person, or in principle. To make a case for immaterialism, he wants to show that appealing to matter is useless and adds no value he will have trouble with the causal story that forms our perceptions. We don"t have a good account of causation.
