There’s nothing saying a pragmatist cannot also be a utilitarian. However, the two are different. One could attempt a derivation of utilitarianism from pragmatism; on the other hand, one could try to attack utilitarianism without abandoning a pragmatic perspective. Furthermore, there are various flavors of utilitarianism as well as various different flavors of pragmatism.
In any case, not all utilitarians claim that forgiveness is a necessary good. Utilitarianism doesn’t necessarily establish the value of any particular acts. Rather, it provides a method for judging the value of a particular act.
Anyway, the question here is about value.
The number 2 is no more present in a pair of apples than the word “good” is present in an ice cream cone. Yet, a rational person can count two apples, and enjoy the ice cream.
If “good” is a value, is it a different kind of value, or is it just like the number 2? The number 2 is a mathematical value. Good is an ethical value. Both are useful types of values because they allow us to measure things.
These terms and others like them are vital for our ability to describe and interact rationally with the world. They do not refer to specific objects, though. Rather, they are perhaps metaconcepts. They refer to a category of concepts. In other words, value terms can refer to anything, and therefore refer to nothing in particular.
Of course, some might say that all concepts are values. The term “car” describes the things we evaluate as “cars.” If values aren’t present in objects, then cars aren’t present in cars, right?
What I suggest is that value terms (numbers, “good,” etc.) are unlike general facts, in that they are purely abstract. Facts are descriptions of experience. Specific values, then, can be used to refer to experience. However, the values themselves are not empirical objects.
How do we get from the value to the fact? That is, if a value term is not an empirical object, then how could something like “car” be used to refer to a real thing? The solution: you can’t be sure that you are talking about a real thing. All you can do is what makes the most sense to you. Clearly you cannot maintain the radical skepticism of “nothing is real.” So, once you realize that some things are real, it’s just a matter of finding reasons to think something is or isn’t real.
I consider value terms organizational aspects of rational thought. They are no doubt the result of evolutionary pressures. Evolution explains why we have rational thought. It also means that values can be studied scientifically. Furthermore, brains would be horribly inefficient if they didn’t provide a functional method for distinguishing between what is real and what is illusion. So, the fact that our brains have evolved to this level of complexity is a strong indication that we are endowed with a remarkable tool for learning about nature.
So, while we may not have a clear and distinct line separating facts and values, we can treat certain concepts as abstractions and others as empirical descriptions. The marginal cases may occasionally prove interesting, but they don’t provide a sufficient cause for abandoning the whole process.
