Yes, quite right (first paragraph). Am I wrong to be confident in my own beliefs? Happy to change my beliefs if your argument is convincing enough.
I think that platonic morality is a social technology with both mechanism and purpose. My definition of platonic morality is “a socially enforced set of informal rules that solve coordination problems for the benefit of the group”. I would judge any particular moral rule set by how well it benefits the group. Slaves benefit their society less than doctors, even if only because resources must be spent to control them, and so they would have a lower moral weight.
Other interesting social technologies include:
Money: Coordinates exchange and stores value through shared belief
Laws: Structure behaviour through formalized rules and consequences
Limited liability companies: Enables pooling capital while limiting risk
Voting: Aggregates preferences into collective decisions
Google says that morality is “principles concerning the distinction between right and wrong or good and bad behaviour.” I think that’s consistent with my definition. I suppose i have added a utilitarian aspect by giving morality a purpose. I do find that things have purposes generally, am I wrong in that or in the specific purpose I have given it?
Agree with Dagon here, when omnizoid say’s “Its obvious that you should” they are calling on the rules of their own morality. Its similar with “Her suffering is bad”, that’s a direct moral judgment. Both statements fall apart when you consider that someone may have different moral rules than you.
For example, in NZ we have an issue with deer destroying our native bush which in turn hurts our native birds. Deer are considered an invasive species and are actively eradicated. In the case when you are actively in the presence of a hurting deer empathy drives you to help, suffering is not pleasant to witness. However I suspect that many NZ’s would condemn every deer in NZ to a painful death, as long as they didn’t have to witness it, in order to save our trees and birdlife.
