Call this (putative) distinction the primary/secondary quality distinction. The distinction between primary and secondary qualities is philosophically interesting because it is (a) often quite attractive to draw such a distinction, and (b) incredibly hard to spell it out in any kind of satisfying and sensible way. I attempt such a spelling-out after first trying to pin down in more detail what we want from the primary/secondary quality distinction, and saying a bit about why that is such a hard thing to get.", pages = "97-119(23)", url = "http://www.ingentaconnect.com/content/ips/ppr/2006/00000072/00000001/art00004" }
