2. Hard Problem of Consciousness  Inadequacy of present day science to deal with consciousness  Varieties of materialism unsatisfactory  Recent challenge from analytic philosophy –Consciousness not logically supervenient on the physical (David Chalmers)  Varieties of idealism, panpsychism, dualism now back on the table  Inadequacy of present day science to deal with consciousness  Varieties of materialism unsatisfactory  Recent challenge from analytic philosophy –Consciousness not logically supervenient on the physical (David Chalmers)  Varieties of idealism, panpsychism, dualism now back on the table

3. QualiaQualia  Intentionality (aboutness) and qualia - two difficult consciousness-related problems  Set intentionality aside  Qualia –First person experience –Hidden –Sensations, perceptions, emotions and thoughts  Intentionality (aboutness) and qualia - two difficult consciousness-related problems  Set intentionality aside  Qualia –First person experience –Hidden –Sensations, perceptions, emotions and thoughts

4. Two conceptions of the physical  Just what is meant by the term “physical”?  Dispositions –Resistance, surface properties, extrinsic  Dispositions contrasted with the categorical  All of present day physics a theory of dispositions?  Categorical –Intrinsic nature of the physical (Russel, Stoljar) –Space, time –Particle, field  Just what is meant by the term “physical”?  Dispositions –Resistance, surface properties, extrinsic  Dispositions contrasted with the categorical  All of present day physics a theory of dispositions?  Categorical –Intrinsic nature of the physical (Russel, Stoljar) –Space, time –Particle, field

5. Intrinsic nature of the physical  Leverage the categorical/dispositional distinction  Categorical as “hidden taxonomy of nature”?  No connection to consciousness at this point  Physics still based on dispositions but tries to infer categorical from dispositional theory?  Leverage the categorical/dispositional distinction  Categorical as “hidden taxonomy of nature”?  No connection to consciousness at this point  Physics still based on dispositions but tries to infer categorical from dispositional theory?

6. Qualia and Science  Very difficult to reconcile science and qualia  Other than materialism and radical emergence (dualism,), all theories face panpsychism problem  Qualia basic?  Qualia supervenient on the categorical?  Very difficult to reconcile science and qualia  Other than materialism and radical emergence (dualism,), all theories face panpsychism problem  Qualia basic?  Qualia supervenient on the categorical?

7. Qualia and the Categorical  Categorical nature of the physical paints an intrinsic picture  Qualia lights up the interior  Interior and Intrinsic connection?  Simple picture: –Nature has an intrinsic categorical structure –Qualia are logically supervenient on categorical (Stoljar)  Categorical nature of the physical paints an intrinsic picture  Qualia lights up the interior  Interior and Intrinsic connection?  Simple picture: –Nature has an intrinsic categorical structure –Qualia are logically supervenient on categorical (Stoljar)

8. The Specter of Panpsychism  Categorical structure not yet fleshed out  Supervenience relationship between qualia and categorical unknown  Categorical structure may allow “low-level” qualia  Categorical structure not yet fleshed out  Supervenience relationship between qualia and categorical unknown  Categorical structure may allow “low-level” qualia

9. CompositionsCompositions  Panpsychism takes qualia all the way down  Compositions - fleshing out the categorical to avoid “naïve panpsychism”  Panpsychism takes qualia all the way down  Compositions - fleshing out the categorical to avoid “naïve panpsychism”

10. Nested Compositions  Simpler compositions necessary but not sufficient for more complex compositions  Spacetime issues set aside  Silent on potential versus actual compositions for the moment  Compositional physics to replace dispositional physics  Simpler compositions necessary but not sufficient for more complex compositions  Spacetime issues set aside  Silent on potential versus actual compositions for the moment  Compositional physics to replace dispositional physics

11. Compositions as basic  Paradoxical quality  Qualia (and dispositions) correlate with compositions  Emergence of context and perspective  Paradoxical quality  Qualia (and dispositions) correlate with compositions  Emergence of context and perspective

12. DiscussionDiscussion  Compositions are the structural-categorical counterpart of qualia –Prehension, sensation, perception, emotion, cognition, intuition, visualization, illumination, pure consciousness event (PCE) all may have categorical counterparts –Dispositions follow suit  Compositions are the structural-categorical counterpart of qualia –Prehension, sensation, perception, emotion, cognition, intuition, visualization, illumination, pure consciousness event (PCE) all may have categorical counterparts –Dispositions follow suit

13. ConclusionConclusion  Most varieties of materialism, idealism, dualism, panpsychim, dual-aspect theories sidestepped  Remains to be seen if compositional physics can be mathematically formulated  Most varieties of materialism, idealism, dualism, panpsychim, dual-aspect theories sidestepped  Remains to be seen if compositional physics can be mathematically formulated
