How do you know if something is morally good or not? What’s the check? What’s your test?

How do you know if something is morally good or not? What’s the check? What’s your test?

Say 2 people are thinking about doing something together.

Say one of them has an idea that is being considered as a common preference (cp). A cp is an idea about how to proceed that they both have no criticisms of.

And say one of them has an objection to that idea. Then it’s not a cp. So it’s not morally ok to act on this idea.

If nobody has any objections, then it’s a cp. So it is morally ok to act on this idea.
