For example, height, weight, color, orientation are objective properties as they can be measured. You can't measure love as you measure height and weight or color - those are observed. You cannot observe human rights, you cannot observe the proposition that "all men are created equal" - this is in the category of of the abstract! You are really lost - you are mixing categories - another logical fallacy. Man, don't you tire of your logical fallacies?
I am not mixing categories. That is specifically why I defined my variables earlier. I am sticking with the concepts of "value" and "worth." You are the one running all over the place dragging in "love" (which could be defined as a chemical cascade in the brain) and "human rights" which evidently did not exist until this century). If you think, by dragging in extraneous concepts, that you might bluff your way out of this, I believe you might have another think coming.
How does one objectively measure "value" or "worth?"
