Moral Realism (or Moral Objectivism) is the meta-ethical view that such things like moral facts and moral values do exist, and that these are objective and independent of our perceptions, our beliefs, feelings or other attitudes towards them. Therefore, moral judgments describe moral facts, which are as certain in their own way as mathematical facts, even though there is no evidence of that.
Example: “Don’t steal chocolate from your friend because the universe will cause your karma to come back on you and have your chocolates stolen or equivalent in some other respect (stolen socks, dinner, etc)” - The example is that the universe has an objective moral code called karma. This cannot be proven nor is there evidence for it, yet people still believe in it.
There are two main variants:
This doctrine holds that there are objective moral properties of which we have empirical knowledge, but that these properties are reducible to entirely non-ethical properties. It assumes cognitivism and that the meanings of these ethical sentences can be expressed as natural properties without the use of ethical terms.
This doctrine holds that ethical statements express propositions that cannot be reduced to non-ethical statements (e.g. "goodness" is indefinable and cannot be defined in any terms).
Moral Realism has the advantage of purportedly allowing the ordinary rules of logic to be applied straightforwardly to moral statements. It also allows for the resolution of moral disagreements, because if two moral beliefs contradict one another, Moral Realism says that both cannot be right at the same time, and so there should be some way of resolving the situation
