What is 'objective' value?

[robvalue]

I think there's no such thing as objective value, where value is used to mean a judgement rather than a measurement. Judgements, by definition, are subjective.

A measurement is something where a prescribed method is used and the answer should be the same no matter who does the measuring, if done correctly.

So if you did want to measure the "objective value" of something, you'd have to develop some sort of formula which defines that value. For an extremely rough example, I could say the "value" of a human life is equal to (150 - age in years). Now anyone could measure the "value" of a particular human at a particular point in time, and they would all get the same result. Of course, there is no guarantee this "value" means anything useful since any particular formula you set up is arbitrary. That value is also abstractly "there" even with no one to measure it, according to this formula.

However, with no agreed method to measure value, each person will come up with their own idea. And with no one to to do the judging, we're left with no judgement and hence no value.
