Well this certainly lives up to the discussion thread title. This is an ill posed question because it selectively carves out a very specific definition of human value for obviously ideological reasons. Why is capital the definitive measure of contributions to the human race? What about the wheel (Mesopotamians), what about fire (Africans - geographically, probably no one knows the taxonomy but certainly not northern Eurasians). What about geometry? Or perhaps something fairly important called numbers. Are those not knowledge?
