Philosophers base their arguments on the truth or falsity of claims made in arguments. If an argument is logically contradictory, that is, any of the premises or the conclusion contradict the other, by necessity the argument must be rejected as false. This is known as the law of non-contradiction (LNC). Indeed, according to Aristotle, it is impossible to know anything if we ignore the LNC. Specifically, in this regard Aristotle states:
“It is impossible that the same thing can at the same time both belong and not belong to the same object and in the same respect, and all other specifications that might be made, let them be added to meet local objections” (Metaphysics, 1005b19–23).
Briefly, the LNC is thus, an explicit modal claim about the incompatibility of opposed properties when applied to the same object. In our course of study, the object of concern is nothing less than ethics itself–moral assertions of right and wrong, good and evil.
Philosopher Gilbert Harman, a noted philosopher who has tried to advocate moral relativism, has pointed out a logical problem with moral relativism. The moral relativist subscribes to three theses:
1.There is no one single true morality that applies universally to everybody in every culture. Instead there are a variety of possible moralities, as is shown by the different beliefs and practices in different cultures.
2.You should respect other people’s moralities and not try to impose your own moral beliefs on them.
3.Thesis number 2 applies universally to everybody in every culture.
The problem, of course, is that Thesis 3 contradicts Thesis 1.
Is there any way someone can be a moral relativist and not be involved in the contradiction Harman points out? That is, Harman, as a relativist, admits that moral relativism is a logically contradictory claim. Does it make logical sense to defend such a position?
