If the term “morality” is going to have any universal applicability to all individuals, it has to be objective. “Subjective morality” doesn’t make any sense; you can hold one or the other, but not both. You might be a cultural or individual relativist with respect to “moral” claims, but they no longer possess the universally binding aspect on all individuals that moral claims are thought to have when we say such things as “torturing babies is wrong.” When we say this, we mean that “‘thou shalt not torture babies’ is to be universally binding all people.”
Certainly there are things almost universally agreed upon, but in that sense it is only objectively a part of our common identity as a species. Torturing a baby is an act where there really aren’t any possible justifications…there’s few things (if any) that one can accomplish by torturing a baby that one could not also accomplish without torturing a baby. Most situations are not so black and white. Let’s take shooting a man in the head with a gun for instance. In general we can say this is a bad thing; but allow me to give you three situations where the same act results in separate judgments.
Scenario A: I walk into a local mall; see a man in the food court; pull out a gun; shoot him in the head just to watch a man die. In this scenario we would all agree that this was wrong…really wrong in fact. My action possessed no justification outside of fulfilling my perverse pleasure. We can all agree that I am a bad person and deserve to be locked up.
Scenario B: I walk into a local mall; a man grabs a womans purse and runs for the door; the woman cries out for help; I shoot man in head. In this scenario, the verdict is a bit more hazy. My actions were arguably justified by the theft. Had I not have shot, he would have escaped out the door with the womans purse; however, was her purse worth taking the thief’s life? Many people will come to very different conclusions about my actions on this occasion. Some will view me a hero, others a villain.
Scenario C: I walk into a local mall; I see a man holding a knife to a child’s throat; the man announces that in 10 seconds he will kill the girl; the man starts counting; I shoot man in the head; girl survives shaken but unharmed. In this scenario, the same act nets a different verdict. This time I am universally viewed as a hero; in fact it could be argued that it would have been immoral not to have shot the man.
Again, same action, three separate verdicts. Morality is dependent upon the circumstances as much as anything else. The consequences of my actions are the basis for how I’ll be judged. Sure, we can come up with a list of acts that are always wrong, but that’s because there is no potential outcome that could possibly justify those particular actions. Ultimately, objective morality is either a tautology (I.e. rape is wrong because rape is wrong) or insufficient (I.e. god said not to do it so don’t do it).
I guess I’m saying that there are no objective morals even if a god exists who ordered us to obey his commands. Merely being a position of authority does not mean that you have the best interest of your subjects at heart. If a god exists, he may have the ability to insist upon our subservience, but that does not mean that his commands are made for our benefit. One can possess legal authority via physical intimidation, but true moral authority lies behind the intent of its origin. This god you suggest invented morality is the same god who invented tornadoes, earthquakes, tsunamis, famines, vicious animal attacks and etc; not exactly the resume of a individual who is concerned about our well being. Either rape is evil because we say it is or because god says it is, either is subjective to the will of the originator. The best morality would be one that came from those who personally stand to gain and lose as a result of its enforcement as it will most likely be the best reflection of the desires of those whose behavior it serves to modify. Again, even if morality is objectively based (rape is wrong because rape is wrong) it would still be dependent upon us to figure this out. We would still be operating under an assumption that we know what is moral and immoral whether it was true or not. I will say this, convincing a person that should they not obey you commands that they burn in hell forever means that they will probably do what you ask, and what they are asked to do is where the trouble usually starts. If morality means nothing more than doing what one is told, then our morality has been kidnapped by a small and often unscrupulous bunch.
