What is right for you may not be right for me, some say .The relativist is saying that a person's belief that he should do something is enough to make it morally right that he should do it .Different climates, different diets, different beliefs, different educations are not enough to make an action right in one place and wrong in another .Relativism has another flaw. It does not recognize that people with different principles come into contact .Moral relativism sounds reasonable, until two groups with different values come into contact, and an action by a person in one group affects a person in another group. When that happens, relativism collapses. The relativist who says that the action is both right and wrong isn't saying anything .That is empty and uninformative .If you are going to have any moral principles at all, then you are going to have to say everyone else should have the same principles. That isn't arrogant. In fact it is humbling."2 .
