On Deriving "Oughts" from "Ises", and the Death of the David Hume Distinction
Neurologically, there seems to be no distinction between "ought" and "is". All "oughts" derive from states in the brain, based on how we think the world
IS, whether that perception happens to be accurate or not. Sam argues that one can improve the quality of their "oughts" by improving the accuracy of their "ises".
That is where the Science of Morality takes off, and that is ultimately what renders the David Hume Distinction outdated. Only philosophers with an interest in taxonomizing human thought would care about such a Distinction. It has no bearing on the empirical reality of how moral values are formed. That is Harris' book in a nutshell.
Perhaps it is useful to split "is" into two types: "The Ontological Is" is how we perceive the world
before we are informed by science. All "oughts" actually derive from "Ontological Ises". "The Empirical Is" is how we perceive the world, once we have been informed by science. Neurologically, an "Empirical Is" becomes indistinguishable from an "Ontological Is",
once the scientific facts are accepted.
My own take distinguishes the "parts" of moral decision making. I admit this is also a model for illustrative purposes, that has little bearing on the empirical world. But, I hope it gives us some insight into exactly where Hume is getting "killed" in the process.
(I am going to refer to the "Miles" analogy I wrote way back in Post #40, so please read that, if you have not done so, already:

The Hume Distinction is
not getting killed in the First Mile, at least not empirically. We have to start with valuing things: science and an evolving sense of well-being*, to name a few. Science
cannot tell us that we
SHOULD value these things**. But, it can tell us HOW or WHY we might tend to value these things. However, this makes very little difference, because David Hume is still going to "die" before this all is over,
in spite of this fact.
(The First Mile is roughly analogous to the "Value Problem" that Sam describes his new afterword.)
(* I can reiterate why well-being is a worthy value, if I must, in another post. But, so far, I have not heard any alternatives that even make any sense.)
(** Though, part of me still thinks even this might change. )
The slow death of the David Hume Distinction actually begins in the Middle Distance. As our tools of science sharpen, they will increasingly point towards how we "
ought" to act. More of our "Ontological Ises" will have started life as "Empirical Ises".
For example, one can scientifically study the impact of corporal punishment applied to school children. We can also construct deep theories as to why it is, or is not, an effective form of discipline, which could then be tested. Apparently, there are still some schools in the U.S. that allow such punishment to occur; despite the fact that it only makes children MORE violent and LESS productive as students. (Harris summarizes this science in the Notes section: page 214 in the hardcover edition, and page 230 in the paperback; note #88.)
Of course, lots of folks might think it was wrong
even before the science came out. But, no one is claiming that other things couldn't go into the middle distance, either. Before science, all of our "ises" were "ontological ises".
The final death blow to this Distinction comes in the Last Mile, where we make our final decision. Compare these two statements:
"Science shows us that corporal punishment discourages obedience, and leads only to more violence, in school children."
And
"Corporal punishment of school children is wrong."
I argue that only English professors (and perhaps philosophers with nothing better to do) would care about the distinction, here. To a sane brain, they would be acted on the same way. The "Empirical Is" has become an Ought, and a basis for one aspect of morality!
If the science was different: If, for argument sake, corporal punishment was consistently proven to encourage good behavior in children, it would become much harder to argue that it was wrong.
And, it is worth reiterating that even those who already "knew" it was wrong, before the science, would still be basing
that judgment on how they perceived the nature (the "is") of the discipline. Their view was simply not as sharp on the facts, than what came out of the science.
It should go without saying that we can prove, scientifically, that any dissenting opinion on this matter is, in fact, wrong.
Perhaps that example was a little too easy? I think the point becomes even clearer when we consider the more
counterintuitive findings related to the science of morality. Consider the unpleasant wrath of the "Peak/End Rule"!
Here, I decided to quote Wikipedia, but only because I am starting to get tired of putting everything into my own words. From
http://en.wikipedia.org/wiki/Peak-end_rule :
In one experiment, one group of people were subjected to loud, painful noises. In a second group, subjects were exposed to the same loud, painful noises as the first group, after which were appended somewhat less painful noises. This second group rated the experience of listening to the noises as much less unpleasant than the first group, despite having been subjected to more discomfort than the first group, as they experienced the same initial duration, and then an extended duration of reduced unpleasantness.
This also applies to exposure to cold and unpleasant medical procedures, such as colonoscopies. It might be morally prudent to
prolong the length of medical procedures, so that the patient
remembers it as less unpleasant than it really was, even though that doesn't sound like it should make sense. Sam talks more about this on page 77 of his book (either edition).
I argue that the old-fashioned, Hume-inspired take on "oughts" is woefully inadequate for handling these sorts of discoveries. And, as we march into the future, we will likely run into more of them. Therefore the David Hume Distinction can be safely ignored by everyone, except maybe historians!
