The only things we can value are things that interest us. Because if we weren't interested then we wouldn't "value" it, we'd be indifferent to it. And since that is the case we shouldn't value anything that doesn't interest us, since "ought" implies "can": it makes no sense to tell someone they "should" do something that they can't. To tell a baby that they must save a woman's life, for example, when they are unable to understand that statement and so can't, makes no sense. It makes no sense to say that something "should be" when it can't be. And so, since then that the only things that can be valued are our interests, it makes no sense to say we should value anything else. How's that for an argument?
