Evolving Ought Beyond Is

Mark Davis2 Comments

The is-ought barrier is a regularly visited topic since its initial formulation by Hume. It certainly seems unassailable in that a syllogism designed to claim that what ought to be done is predicated on what is (observable and natural) must always fail. The reason for this is that the ought framework (call it ethics) can be formulated in any particular way to ascribe the good and the bad. A serial killer might believe that killing certain people eliminates demons from the world and is therefore good, regardless of a general prohibition that killing others is bad. In this case, we might argue that the killer is simply mistaken in her beliefs and that a lack of accurate information is guiding her. But even the claim that there is an “is” in this case (killing people results in a worse society/people are entitled to be free from murder/etc.) doesn’t really stay on the factual side of the barrier. The is evaporates into an ought at the very outset.

There are efforts to enliven some type of naturalistic underpinnings of moral reasoning, like Sam Harris’s The Moral Landscape that postulates an adaptive topology where the consequences of individual and group actions result in improvements or harm to humanity as a whole. The end result is a kind of abstract consequentialism beneath local observables that is enervated by some brain science. Here’s an example: (1) Better knowledge of the biological origins of disease can result in behavior that reduces disease harm; (2) It is therefore moral to improve education about biology; (3) Disease harm is reduced resulting in reduced suffering. This doesn’t quite make it across the barrier, though, because it presupposes an ought for humans that reduces the imperatives of the disease itself (what about its thriving?),… Read the rest

Quantum Field Is-Oughts

teleologySean Carroll’s Oxford lecture on Poetic Naturalism is worth watching (below). In many ways it just reiterates several common themes. First, it reinforces the is-ought barrier between values and observations about the natural world. It does so with particular depth, though, by identifying how coarse-grained theories at different levels of explanation can be equally compatible with quantum field theory. Second, and related, he shows how entropy is an emergent property of atomic theory and the interactions of quantum fields (that we think of as particles much of the time) and, importantly, that we can project the same notion of boundary conditions that result in entropy into the future resulting in a kind of effective teleology. That is, there can be some boundary conditions for the evolution of large-scale particle systems that form into configurations that we can label purposeful or purposeful-like. I still like the term “teleonomy” to describe this alternative notion, but the language largely doesn’t matter except as an educational and distinguishing tool against the semantic embeddings of old scholastic monks.

Finally, the poetry aspect resolves in value theories of the world. Many are compatible with descriptive theories, and our resolution of them is through opinion, reason, communications, and, yes, violence and war. There is no monopoly of policy theories, religious claims, or idealizations that hold sway. Instead we have interests and collective movements, and the above, all working together to define our moral frontiers.
