Not sure why this got removed from 196lemmy..blahaj.zone but it would be real nice if moderation on Lemmy gave you some sort of notification of what you did wrong. Like an automatic DM or something
I'm seeing this point about moral epistemology a lot in this thread. Of course, philosophers have constructed convincing arguments in favor of different theories (classic ones being virtue ethics, deontology, consequentialism). If you were to take a look at those arguments you might be persuaded to one camp or another.
Also, I find this objection makes more sense for the moral skeptic than the moral relativist. If we really can't know the moral value of an action, then why settle for saying its based on what humans think? Why not just go all out and say either 1) there is no such thing as moral value or 2) there is moral value but we have no way of knowing what it is.
