The principle “You can’t be judge in your own cause” is both selfevident and powerful. It is the principle that compels us to recognize that the ethical enterprise entails submitting to a higher judgment than our own first judgment. Moreover, it is the principle that commits us to conceding that ethical judgments are objective. Those two conclusions are accepted by many moralists. There is a third conclusion that, unless I am mistaken, follows just as inexorably as these two, but is rarely, if ever, accepted in modem discussions. If you can’t be judge in your own cause you commit yourself to depend on the praise and blame of a judge who is competent to judge your cause. The principle “Not judge in one’s own cause” entails an ethics of reward and punishment, because praise is a reward and blame a punishment.

“Notjudge in one’s own cause”

The principle “You cannot be judge in your own cause” is self-evident. It ordinarily applies in cases where I am in dispute with someone else over property: perhaps over ownership of land or fishing rights or the proceeds of a will. The principle is extended to cover issues such as the ban on an examiner from examining a relative, or a magistrate from presiding at the trial of a business associate.

No one doubts the applicability of the rule in these relatively unproblematic cases. What could be easier, it might be argued (but never is) than discounting one’s tendency to severity or to leniency when examining one’s own child? Yet most moral dilemmas are far more difficult than property disputes and arguments over examination grades. Every dispute inevitably involves the “cause” of every disputant.

I am indebted to Clement Dore for directing my attention to the importance of the Ideal Observer in moral discourse. He argued in 1976, and has repeated the argument in 1991, that if something is morally obligatory for a given person, that might well be the same as God's being disposed to disapprove of that person's doing what is morally obligatory. God is “the supremely perfect Ideal Observer”.Dore, Clement, Moral Scepticism (Library of Philosophy and Religion; London:Macmillan,1991), 39CrossRefGoogle Scholar, 33–47, referring to an article, “Ethical Supematuralism” Sophia, (1976).
