Ideal Decision Making and Green Virtues

Abstract

One feature of Utilitarianism that provides its link to rational decision making is that the basic principle of utility demands that one maximize the good. One can disagree about what exactly the good is – perhaps it is pleasure, autonomy, beauty, or some set of items on a list mixing a variety of intrinsic goods. However, whatever the good turns out to be, we ought – morally – to maximize it. A failure to maximize the good is seen as not only a moral failure but also a rational one. So, for example, suppose that a friend of yours offers you a choice between $100 and $10. Most would hold that the rational thing to do is maximize the good and take the $100, all other things being equal. The person who took the $10 option would be considered irrational and imprudent. Maximizing or optimizing one's finances, all other things being equal, would be prudent, but the general point about maximizing carries over to the moral area. What one ought to do, morally, is maximize the good. In the moral area, this means maximizing human well-being, impartially considered. The above illustration is an artificial one, and real life introduces all sorts of complexities such as how to weigh disparate goods and how to deal with risk and uncertainty. However, the basic point that one ought to maximize the good, or do the best one can, stands.
