My views on objective morality

[robvalue]

Objective means independent of viewpoint or opinion.

Hair colour is objective, as long as we all agree what colours mean what and such. We can have a particular way of measuring its colour which reduces it to its constituents. As long as we all use the same method, we get the same answer.

Of course, recognising by eye what the exact colour is isn't always reliable. That would be an estimate about a fact.

If you can give me a way to determine the morality of an action, that doesn't rely on anyone's opinion about that action, I'd be very interested. Then you have to tell me why I should care about whatever method you've come up with.

We agree on objective ways of assessing reality because it is useful to do so. It's not useful to do the same with morality, as far as I'm concerned.
