It seems to me that there are three, distinct challenges put forward thus far:
1. There is no scientific basis to say that we should value well-being, our own or anyone else’s. (The Value Problem)
2. Hence, if someone does not care about well-being, or cares only about his own and not about the well-being of others, there is no way to argue that he is wrong from the point of view of science. (The Persuasion Problem)
3. Even if we did agree to grant “well-being” primacy in any discussion of morality, it is difficult or impossible to define it with rigor. It is, therefore, impossible to measure well-being scientifically. Thus, there can be no science of morality. (The Measurement Problem)I believe all of these challenges are the product of philosophical confusion. The simplest way to see this is by analogy to medicine and the mysterious quantity we call “health.” Let’s swap “morality” for “medicine” and “well-being” for “health” and see how things look:
1. There is no scientific basis to say that we should value health, our own or anyone else’s. (The Value Problem)
2. Hence, if someone does not care about health, or cares only about his own and not about the health of others, there is no way to argue that he is wrong from the point of view of science. (The Persuasion Problem)
3. Even if we did agree to grant “health” primacy in any discussion of medicine, it is difficult or impossible to define it with rigor. It is, therefore, impossible to measure health scientifically. Thus, there can be no science of medicine. (The Measurement Problem)While the analogy may not be perfect, I maintain that it is good enough to obviate these three criticisms. Is there a Value Problem, with respect to health? Is it unscientific to value health and seek to maximize it within the context of medicine? No. Clearly there are scientific truths to be known about health—and we can fail to know them, to our great detriment. This is a fact. And yet, it is possible for people to deny this fact, or to have perverse and even self-destructive ideas about how to live. Needless to say, it can be fruitless to argue with such people.
To what does the phrase, “within the context of medicine,” correspond in the original template, which is: “1. There is no scientific basis to say that we should value well-being, our own or anyone else’s. (The Value Problem).”?
One must assume that the missing (implied) phrase is “within the context of life.” But the problem with this is obvious. “Medicine” is, by definition, the area of inquiry concerned with human health. On the other hand, there is no such definition of “Life”. Life is not an area of inquiry. Life does not have a set of one or more objectives that we all (necessarily) agree upon (by definition). That is the crux of the objection to Harris’ position. The success of this analogy depends on our willingness to acknowledge that “well-being” is just as obviously the objective of life as health is the objective of medicine. But, clearly, this is begging the question.
It’s not necessary to go further. It is this first step that Harris can not justify no matter how hard he tries. “Well-being” is a value like any other. There is no way to rationally establish either its primacy or universality.
