Abstract

Conscious experience has been said to be outside of, or alien to, physics, and unexplained in a physical world. However, it is argued here that experience is entirely expected in a physical world that can only be defined by its power to determine patterns of experience. Something physical is something with the type of causal power that can contribute to determining the content of an experience if a subject is present at the right place and time. Physical powers also interact with other physical powers, distant from any given subject, to form chains, and it is these interactions that physics handles mathematically. Nevertheless, actual causation is always defined by reference to determination of experience. The apparent puzzle of why there should be a link between experience and the physical may relate in part to the fact that experience is always immediately causally proximal, always 'here and now', at least as far as we can ascertain. Proximality, and with it the potential for mentality, cuts across existential/ ontological categories. Experience also requires a concept of an intrinsic individual, in order for there to be individual points of view. The practical problem for consciousness studies is to identify intrinsically individual causal units with event domains in human brains, that can have points of view and content that could fit with human experiences, in a way consistent with current physics. It is suggested that the 'causal diamond' concept of the here and now explored by Savitt (2015) and Arthur (2019), together with principles of field theory, may provide a useful starting point.
