This ties into my post on the divine command theory in that if god is the sole judge and source of what is moral, then morality is ultimately subjective and arbitrary, which also ties into the Euthyphro dilemma which was outlined on that page. But if morality isn’t subjective, then by what objective criteria can we set to determine if an action is objectively moral or not?
That may seem like a hard question to ponder, but it really isn’t. Here is one way to determine if an action is objectively moral or not: An action is objectively moral if it serves to promote human flourishing, or if it minimizes needless harm and/or suffering, and an action is immoral if it promotes pain and suffering or harms human flourishing in some way.
Those are the criteria that Scott Clifton of soap opera fame, but who is also on Youtube under the handle “TheoreticalBullshit” put it, and I am inclined to agree with him on this. That way morality isn’t subjective and ultimately arbitrary, and also provides an answer to the Euthypro dilemma, in my eyes at least.
