Description
Panpsychist double aspect theory, the most promising version of panpsychism, holds that the mental and the physical are mutually irreducible properties, or features, of ultimate matter, therefore they both are ontologically fundamental and ubiquitous. This version of panpsychism involves the following two notions: anti-reductivism and anti- emergentism. The former states that mental phenomena are not recordable in terms of physics. The latter implies that mental phenomena do not causally arise only from a certain macroscale physical condition, and the mental and the physical do not constitute an ontological hierarchy. From these notions, it follows that any macroscale mental phenomenon is the result of a combination of ultimate mental properties. Yet this idea creates the combination problem: how higher level mentality, e.g., human or animal consciousness, arises from lower level mentality, the ultimate mental "particles." Panpsychist double aspect theory purports to find the proper location of mind in the world without being vulnerable to typical mind-body problems. Nevertheless, since this version of panpsychism explains the ontological structure of higher level mentality as analogous to the atomic structure of a molecular physical entity, the combination problem arises. In Chapter 1, I explain the general conception of panpsychism. Chapter 2 shows the plausibility of panpsychist double aspect theory and how the combination problem arises from this version. I discuss the history and implications of the combination problem in Chapter 3. In Chapter 4, I introduce some alternative versions of panpsychism that do not raise the combination problem, and point out their implausibility. The intelligibility of mental combination is explained in Chapter 5. The moral of these chapters is that our epistemic intuition that mind is not composed of "smaller" minds fails to undermine the possibility that mind is structurally complex. In Chapter 6, I argue that C. Koch and G. Tononi's integrated information theory (IIT) is a form of panpsychism, and that the IIT can serve as a model for solving the combination problem. However, I am not committed to the IIT, and I point out theoretical weaknesses of the IIT besides the combination problem.

Description
Given the success of science, weak forms of mind-brain dependence are commonly treated as uncontroversial within contemporary philosophies of mind. More controversial are the different metaphysical claims inferred from this dependence, many ascribing ontological priority to the brain. Consider the following three propositions: (i) neurological events are essentially identified by their role in material systems, laws, and causes that are constitutively non-rational; (ii) at least some mental events are essentially identified in virtue of their role in the use of reason; (iii) all mental events are realized by, identical to, or composed out of, neurological events. (i) is uncontroversial. However, (iii) is strictly materialistic. (i), (ii) and (iii) taken together appear incoherent. A fruitful task for philosophy is to resolve this apparent incoherence. In his 1997 book The Last Word Thomas Nagel offers an explication of reason that conceptually transcends the nature of material substrate. In his 2010 article "Modest Dualism" Tyler Burge offers reasons to think of propositional thought as irreducible to the concepts of the material sciences. Both focus on rationality as a unique form of intentionality. Both philosophers also reject materialism (iii). On their accounts it's reasonable to take 'rational intentionality' as exhibiting a logical priority of the mind with respect to the brain in inquiries into the nature of mind. Granting this, the diminished conception of mind presupposed by prevailing contemporary theories is seen to be the result of a more general failure to recognize the logical priority and intricate nature of rationality. The robust views of rationality expressed by Nagel and Burge constitute grounds for argument against even the weakest form of materialism. I develop such an argument in this thesis, showing that the propositional attitudes exhibited in thought and speech preclude all materialistic notions of mind. Furthermore, I take the nature of propositional attitudes to suggest a perspective for exploring the fundamental nature of mind, one that focuses not on composition but on rational powers.
