‘Physics gives us behavioural structure; panpsychism is a proposal about what underlies that behavioural structure. Think about a mathematical model in economics that’s just a bunch of equations that abstracts away from the concrete realities of labour, prices, etc. The reality of labour doesn’t add to the reality specified by that model; to the contrary, labour is the very thing one of those symbols refers to! Similarly, according to panpsychism, physics gives us mathematical models that abstract away from the concrete reality of a universe filled with consciousness. The term ‘mass’ refers to something that physics characterises in terms of its behaviour but which in its intrinsic nature is a form of consciousness. If that view makes sense, then there’s no conflict with physics.’
— Philip Goff, Is Panpsychism Inconsistent with Physics?
There are two ways of developing the basic panpsychist position. One is micropsychism, the view that the smallest parts of the physical world have consciousness. Micropsychism is not to be equated with the absurd view that quarks have emotions or that electrons feel existential angst. In human beings, consciousness is a sophisticated thing, involving subtle and complex emotions, thoughts and sensory experiences. But there seems nothing incoherent with the idea that consciousness might exist in some extremely basic forms. We have good reason to think that the conscious experience of a horse is much less complex than that of a human being, and the experiences of a chicken less complex than those of a horse. As organisms become simpler, perhaps at some point the light of consciousness suddenly switches off, with simpler organisms having no experience at all. But it is also possible that the light of consciousness never switches off entirely, but rather fades as organic complexity reduces, through flies, insects, plants, amoeba and bacteria. For the micropsychist, this fading-while-never-turning-off continuum further extends into inorganic matter, with fundamental physical entities – perhaps electrons and quarks – possessing extremely rudimentary forms of consciousness, to reflect their extremely simple nature.
