Hume on the Distinction between Primary and Secondary Qualities
Abstract
In this paper, I argue that Hume has an insight into the heart of most of “new philosophy” when he claims that according to it, proper sensibles are not Real properties of material substance and Real bodies. I call this tenet “the Proper Sensibles Principle” (PSP). In the second part of the paper, I defend the interpretation - mainly against Don Garrett’s doubts - that the PSP is a rational tenet in Hume’s view and he thus endorses it. Its rationality means that the PSP has a firm foundation in inductive-causal reasoning.
