| | Regarding reasoning in general, using precedents to ennunciate a rule is much like induction. The role of principle is obvious. Policy, I think, is a top-down kind of thinking, where membership in a category somewhat higher up in the hierarchy of knowledge is referred to in order to settle a question at that lower level.
Regarding individual moral choices, precedents are very useful to work out why a similar, previous choice--presumably thought to be sound--belonged in the category of what is morally right, and, through extension, to indicate that this choice does (or doesn't,) also. (Like, "We loaned money to your sister, how can we refuse to loan it to your brother?") I think we all do this very often, with the difficult part being sorting out the differences between past cases and the present one, (like, "Yes, but she doesn't hop from job to job, with long periods of inactivity between,") and judging whether or not those differences make a difference... Principle in moral choices is important in a straight-forward way. If you don't have principles that cover a particular case, (like, you find yourself thinking, "Is it wrong to do to someone what everybody else is getting away with?" forget deciding that case until you go back and formulate your principles more thoroughly. Policy might have no bigger role than one's gut reaction to the case at hand. But gut reaction is very important, because it speaks from your sense of life. Still, it cannot be relied on without getting the principle, and, implicitly, the precedents straightened out. Courts may be happy to rely on one (or two) of these three modes of argument, and content to ignore the other(s), but moral thinking can't do that. Epistemologically, precedents are the concretes summarized by principle, which is a general rule, and policy is the relevance of the higher categories in one's hierarchy of knowledge. So, hierarchically, it is: policy, principle, precedent, in top-down order. You might collapse policy and principle into two levels of principle, I guess, but you can't dispense with principle at the lower level. We can't get from "man's life" to "fraud is wrong" without intermediary steps, it is contrary to psychological factors of cognition, attention span, etc. Since we need the relevant principle per se, the higher contributions are "felt" in the sense-of-life way. So, I would claim that we do, indeed use all three types of information in arguing and deciding moral choices, but in the case of philosophical reasoning, which moral reasoning is, all must agree. In simple cases, we may only need to use a principle, and not to review precedents, but the gut reaction that represents policy would automatically weigh in.
As an exercize in applying this, I'll try to point out each in this post, above: The examples I gave, which are in parentheses, are cited as precedents would be, they are chosen to be examples we would all agree to as belonging in one or another category, they are supposed to be exemplars of their category, telling concrete instances. Policy is the admonition that there must be agreement among all the categories of information. That is logical principle devolving onto any process of thought or decision-making. The principle here is one about decision-making. Decision-making in moral contexts must be based on a validated principle that states or recognizes the standard of value, it should not be made on emotional grounds, nor from a short-range estimate of consequences, etc. Trivial decisions can, properly, be made on such grounds, but moral decisions require other bases. The principle here is that moral decisions must be principled.
Does that get it?
