Show moreI find myself agreeing with almost everything in Harris’s defense of moral theory except the end: moral theories can often be useful in resolving moral dilemmas. Both students and practitioners of practical ethics should be constantly reminded of this, because in practical ethics we need all of the help we can get. If (as it seems) these two sentences state the conclusion, Harris has committed a non sequitur. While making a good argument for the general usefulness of moral theory in practical ethics, he has not made any argument for its usefulness to students or practitioners as such. He has simply assumed that what is true of some who engage in practical ethics is true of students and practitioners in particular. In theory, of course, moral theory should be useful even to students and practitioners, helping them to identify issues they might have overlooked, to seek information they might otherwise not have thought relevant, and to formulate courses of action that might not otherwise have occurred to them. In practice, however, moral theory will seldom, if ever, be useful (or, at least, useful enough). We do not (as Harris claims) need all the help we can get in practical ethics. What we need is all the help we can get at reasonable cost. We should only invest the time and effort needed to learn and use moral theory when the investment is no greater than for an otherwise equally useful alternative. Since there is at least one equally useful alternative requiring much less investment, the time and effort students and practitioners would have to invest in moral theory will (in general) be much greater than necessary for their purposes. So, neither students nor practitioners need moral theory. Teaching Ethics Vol. 10, Issue 1, pp. 69-78 Show less
