No, it isn’t, in my opinion. But Alex Wendt thinks otherwise in Quantum Mind and Social Science: Unifying Physical and Social Ontology. In fact, he thinks a solution to the mind-body problem is crucial to a coherent social science. Which is to say, in Wendt’s words:
Some of the deepest philosophical controversies in the social sciences are just local manifestations of the mind–body problem. So if the theory of quantum consciousness can solve that problem then it may solve fundamental problems of social science as well. (5)
But physicalist philosophers of mind are not persuaded by the discontinuity argument. As we have noted many times in this place, there are abundant examples of properties that are emergent in a non-spooky way. It simply is not the case that the sciences need to proceed in a Cartesian, foundationalist fashion. We do not need to reduce each level of the world to the workings of a lower level of things and processes.
Panpsychism takes a known effect at the macroscopic level–that we are conscious–and scales it downward to the sub-atomic level, meaning that matter is intrinsically minded. (30)
Exploiting this possibility, quantum consciousness theorists have identified mechanisms in the brain that might allow this sub-atomic proto-consciousness to be amplified to the macroscopic level. (5)
Quantum consciousness theory builds on these intuitions by combining two propositions: (1) the physical claim of quantum brain theory that the brain is capable of sustaining coherent quantum states ( Chapter 5 ), and (2) the metaphysical claim of panpsychism that consciousness inheres in the very structure of matter ( Chapter 6 ). (92)
Panpsychism strikes me as an extravagant and unhelpful theoretical approach, however. Why should we attempt to analyze “Robert is planning to embarrass the prime minister” into a vast ensemble of psychic bits associated with the sub-atomic particles of his body? How does it even make sense to imagine a “sub-atomic bit of consciousness”? And how does the postulation of sub-atomic characteristics of consciousness give us any advantage in understanding ordinary human consciousness, deliberation, and intentionality?
Another supposedly important issue in the domain of the mind-body problem is the problem of freedom of the will. As ordinary human beings in the world we work on the assumption that individuals make intentional choices among feasible alternatives; their behavior is not causally determined by any set of background conditions. But if individuals are composed of physically deterministic parts (classical physics) then how is it possible for the organism to be “free”? And equally, if individuals are composed of physically indeterministic parts (probabilistic sub-particles) then how is it possible for the organism to be intentional (since chance doesn’t produce intentionality)? So neither classical physics nor quantum physics seems to leave room for intentional free choice among alternatives.
Social theory presupposes intentional actors; but our current theories of neuroscience don’t permit us to reproduce how intentionality, consciousness, and freedom are possible. So don’t we need to solve the problem of freedom of the will before we can construct valid sociological theories that depend upon conscious, intentional and free actors?
Again, my answer is negative. It is an interesting question, to be sure, how freedom, consciousness, and intentionality can emerge from the wetware of the brain. But it is not necessary to solve this problem before we proceed with social science. Instead, we can begin with phenomenological truisms: we are conscious, we are intentional, and we are (in a variety of conditioned senses) free. How the organism achieves these higher-level capabilities is intriguing to study; but we don’t have to premise our sociological theories on any particular answer to this question.
So the position I want to take here is that we don’t have to solve the mysteries of quantum mechanics in order to understand social processes and social causation. We can bracket the metaphysics of the quantum world — much as the Copenhagen interpretation sought to do — without abandoning the goal of providing a good explanation of aspects of the social world and social actors. Wendt doesn’t like this approach:
Notwithstanding its attractions to some, this refusal to deal with ontological issues also underlies the main objection to the Copenhagen approach: that it is essentially incomplete. (75)
But why is incompleteness a problem for the higher-level science (psychology or sociology, for example)? Why are we not better served by a kind of middle-level theory of human action and the social world, a special science, that refrains altogether from the impulse of reductionism? This middle-level approach would certainly leave open the research question of how various capabilities of the conscious, intentional organism are embodied in neurophysiology. But it would not require providing such an account in order to validate the human-level or social-level theory.
