An aircraft with all the relevant mechanical properties will indeed be able to fly. But flying, unlike subjective experience, is a purely functional property. Being 3rd-personally indistinguishable from a being with 1st-personal experiences doesn't logically imply having 1st-personal experiences.

I have a recent paper on whether AI systems could have free will and how we might approach this question: doi.org/10.1007/s112...
doi.org
Can AI systems have free will? - Synthese
While there has been much discussion of whether AI systems could function as moral agents or acquire sentience, there has been very little discussion of whether AI systems could have free will. I sketch a framework for thinking about this question, inspired by Daniel Dennett’s work. I argue that, to determine whether an AI system has free will, we should not look for some mysterious property, expect its underlying algorithms to be indeterministic, or ask whether the system is unpredictable. Rather, we should simply ask whether we have good explanatory reasons to view the system as an intentional agent, with the capacity for choice between alternative possibilities and control over the resulting actions. If the answer is “yes”, then the system counts as having free will in a pragmatic and diagnostically useful sense.

Now published: a seven-pronged no-go result for quantum mechanics (QM). Seven classically accepted theses about physical reality are jointly inconsistent with QM. Any six are consistent. Different interpretations of QM can be classified in terms of which theses they give up and which they retain.

I think free will requires three things: 1. intentional agency, 2. alternative possibilities for choice, 3. causal control over one's actions. Resource-constrained agents can and do routinely satisfy these conditions, as exemplified by the human case. Here I discuss my broader views on free will.

Can artificial agents have free will? Here is a framework for thinking about this question. I discuss two kinds of artificial agents: group agents (e.g., corporations, states etc.) and AI systems (e.g., LLMs, autonomous decision-making systems etc.). Both raise important questions of responsibility.

Here is a social-choice-theoretic critique of the notion of "the will of the people". The talk revisits William Riker's critique of populism (from his 1982 book Liberalism against Populism) and develops it further. At first sight, Riker's book may look dated, but the topic has become timely again.

The statement illustrates that a purely objective and impersonal account of reality (which we find in ordinary science and functionalist philosophy of mind) cannot properly accommodate phenomenal consciousness. Consciousness involves irreducibly first-personal facts. Here is a summary of my view.

Personally, I am particularly interested in the escape routes from the heptalemma that relax one of the four theses that jointly entail the original realism thesis in Bell's theorem, namely measurement realism, non-relationalism, non-fragmentation, and one world. But the paper is officially neutral.

Christian List @clist.bsky.social · 13/03/2026
If we consider the rejection of measurement independence, I can see the argument that the retrocausal route has some advantages over the superdeterministic route, as it allows the observers' measurement settings to remain exogenous, albeit at the "cost" of reversing the relevant causal direction.
110
Christian List @clist.bsky.social · 13/03/2026
In this paper, we just taxonomize the different possible escape routes from the heptalemma without endorsing one of them. We assume that every such route, by rejecting one of seven initially plausible theses, involves some cost. It is then a matter of judgment which route is least costly on balance.

Christian List @clist.bsky.social · 12/03/2026
Updated: "A Heptalemma for Quantum Mechanics" (with John DeBrota). We present a no-go result: seven initially plausible theses about physical reality are jointly inconsistent with the predictions of QM, while any six are jointly consistent. The upshot is a novel taxonomy of interpretations of QM.
