 Theories also strive for simplicity, coherence, and accuracy. The fewer epicycles the theory has to postulate the better, the parts of the theory should fit well together. For example, the theory should not contain inconsistent principles, or have inconsistent implications. The theory should cover the phenomena in question. In the case of moral theories, the phenomena in question are thought to be our considered moral intuitions or judgements. Another coherence condition involves the theory cohering with a person’s set of considered judgments, as well.
