Subjective Morality?

[robvalue]

You can go ahead and test hypotheses about assumed objects, without having to care about how "real" any aspect of the whole thing is. The results are there, and they make a difference. And clearly, you can test whether you can do such tests by... doing tests and getting the results.

You can’t test for morality in the same way; you can test for outcomes, and then assign values to those outcomes. Or you can assign values first, justifying them however you like, and then test for outcomes. You can’t test for the values, because they don’t even represent real objects by assumption. If they did, then the whole business would be entirely different.
