If those who say that ethics is subjective mean by this that when I say that cruelty to animals is wrong I am really only saying that I disapprove of cruelty to animals, they are faced with an aggravated form of one of the difficulties of relativism: the inability to account for ethical disagreement. What was true for the relativist of disagreement between people from different societies is for the subjectivist true of disagreement between any two people. I say cruelty to animals is wrong: someone else says it is not wrong. If this means that I disapprove of cruelty to animals and someone else does not, both statements may be true and so there is nothing to argue about, and the whole field of ethics is dead, because there is no room for reason or argument. So what does it mean that something is right or wrong?
