Fresh Perspectives on The Mind-Brain Debate | Roundtable on Philosophy of Mind, Pt. 1.

The Problem of Physicalism

The podcast episode discusses the ongoing debate in philosophy of mind regarding the nature of consciousness and whether it can be fully explained by physical processes. The speakers highlight the challenge that physicalism faces in accounting for subjective experiences, intentionality, and other mental properties. They explore different physicalist models, such as functionalism, but argue that these models fail to fully explain the unique features of consciousness. They suggest that physicalism struggles to bridge the categorical gap between physical and mental properties, leading to the emergence of alternative viewpoints like panpsychism and eliminativism.

The Challenge of Emergence

The concept of emergence is examined in relation to the mind-body problem. While some forms of emergence, such as liquidity arising from water molecules, are seen as plausible and explainable through reductionist approaches, the speakers argue that the emergence of consciousness poses unique challenges for physicalist explanations. They question how a purely physicalist perspective can account for the subjective experiences, intentionality, and other qualities of the mind that do not seem reducible to physical properties. They argue that the emergence of mental phenomena from physical processes requires further examination and consideration.

Critique of Functionalism

The speakers discuss functionalism as one of the prominent physicalist models in philosophy of mind. Functionalism attempts to explain the mind by focusing on the functional roles and causal interaction of mental states. However, the speakers point out that functionalism fails to capture the essence of subjective experiences and consciousness. They highlight the problem of consciousness, asserting that even if functional accounts can explain the behavior and functional aspects of mental states, they do not provide an adequate explanation for the nature of consciousness itself.

Panpsychism and Eliminativism

The podcast explores two extreme positions within the philosophy of mind: panpsychism and eliminativism. Panpsychism posits that consciousness is a fundamental property of the universe and is present in all physical entities. Eliminativism, on the other hand, denies the existence of consciousness altogether and suggests it is an illusion or a mere byproduct of physical processes. The speakers acknowledge the challenges faced by both positions, with panpsychism requiring a redefinition of physicalism and eliminativism facing the problem of denying something that seems to be phenomenologically undeniable. These positions highlight the complexity of the debate surrounding the nature of consciousness and the limitations of physicalism in addressing it.
