Heres an excerpty of an article I stumbled across while reading about reletivism for my ethics class (I realize its fairly long)
"It seems that ethical claims are normative: they do not merely state descriptive facts; they prescribe or endorse or encourage certain actions.15
Both ethical relativists and ethical objectivists generally agree so far. The disagreement comes when the anti-objectivist asks how it is possible for any claim to be normative. What is normativity, after all? How does normativity fit into “the fabric of the world”?16 Physics describes for us a universe of atoms, electrons, protons, neutrons, electromagnetic and gravitational fields, etc. Biology describes a world of living organisms with drives to eat, reproduce, etc. How does normativity fit into the natural world? The anti-objectivist answers that the only way to scientifically explain the normativity of ethical claims is in terms of how these claims engage a person’s feelings, or passions, or commitments, or some such human psychological motivation.17 Thus, the source of the normativity which ethical claims seem to have is their necessary connection with human motivations (such as desires, passions, etc.).18
For example, say I agree with the claim that murder is wrong. This is an ethical claim, so it is normative. The anti-objectivist will say that what accounts for the normativity of an ethical claim is that, when I agree with the truth of the claim, I am implicitly acknowledging the existence of a motivation to act in accordance with that claim.
Here is another way of thinking about it. Recall my earlier suggestion that, if you acknowledge the truth of an ethical claim, you must admit its relevance to your actions. The anti-objectivist will explain this fact as follows: if you acknowledge the truth of an ethical claim you must admit its relevance to your actions because that ethical claim is true only if you are psychologically motivated to act in accordance with it. The truth of an ethical claim implies the existence of some motivation to follow that claim. Notice a further implication of this view: if there is no motivation to follow an ethical claim, then that claim is not true.
The third premise is one that I think almost all of us would agree with today: when it comes to ethical topics, people frequently do not share the same motivations (i.e., often one person has a certain motivation and another person does not have it, or has an opposed motivation). For example, some people find homosexuality disgusting, while others find it perfectly acceptable. Some people feel strongly that murderers should receive the death penalty, while others feel just as strongly that executing murderers is barbaric. Some people desire to prevent women from having abortions, while others desire just as much to ensure that women have the choice to have abortions. We could go on all day with additional examples.19
On the basis of the above premises, the ethical relativist concludes that all ethical claims are true or false only in relation to each individual person’s particular viewpoint or perspective – where “viewpoint” or “perspective” includes one’s motivations. Can you see why this conclusion follows from the premises? The argument is that ethical claims are normative, and that what makes them normative is that the truth of an ethical claim implies the existence of a corresponding motivation. But people have different motivations regarding ethical issues, so ethical claims are true only relative to those who have the appropriate motivations. Thus, for example, if I lack the motivation to disapprove of stealing, then the claim that stealing is wrong will not be normative for me. But if it is not normative, then it cannot be true relative to me either, because a true ethical claim is always normative."
How does one argue against this? I have trouble asserting that by holding the value of life, the rational position on various issues follows logically, but on certain things it seems to come down to individual (preferential) values. For example, whether one sees your ailing grandmother or sees a concert depends on how you value time with your grandmother versus personal entertainment. This, they claim, makes it a form of subjectivism/relativism. I, personally, am at a loss to frame this in a way that works. Any help would be appreciated.
