"......if my son was dying I would choose his life over that of a pig, that is likely true. But by the same token I would choose my son's life over YOURS. Does that mean his life is intrinsically worth more? If not, then you also need to explain how you come to your conclusion on intrinsic worth from statements about subjective worth........."

The last poster has done us an important service. Raised the issue of the RELEVANCE of "intrinsic worth". In other words, need to explain not statements about intrinsic vs subjective worth but ones indicating that "intrinsic worth" sometimes/ever controls our ethical decisions. Because if not, then whether or not "intrinsic worth" exists becomes besides the point.
