Johannes Kleiner moved page Chalmers' xiomatization to Chalmers' Axiomatization: Consisten
This page summarizes David Chalmers' an axiomatization of a theory of conscious experience in inspired by the early work of David Chalmers (Chalmers, 1996<ref name="mind">Chalmers, David J. The conscious mind: In search of a fundamental theory. Oxford university press, 1996.</ref>; Chalmers, 2010<ref name="character">Chalmers, David J. The character of consciousness. Oxford University Press, 2010.</ref>).We remark that the following outline of Chalmers' grounding is intended to highlight the relations among various constituents concepts from Chalmers' work as they could figure in a proper grounding of his groundingand the scientific study of consciousness. It is primarily not intended to be of an introductory natureintroduction to the philosophy laid out by David Chalmers.
== Physical domain ==
First, we note that Chalmers' definition of "physical domain" includes what is often called "material" or "physical" configurations, such as neurons or brain tissue,
as well as more fundamental physical notions such as "mass, charge, and space-time"<ref name="character" />Chalmers, David J. The character of consciousness. Oxford University Press, 2010.</ref> or "atoms, electro-magnetic fields, and so on"<ref name="mind" />.We thus define the term ''physical domain'' to refer to all those phenomena which are currently considered to be the subject of a natural science (i.e. subjects of physics, chemistry, earth science, biology, etc.).
== Causal closure ==
Chalmers assumes that
== Function, structure and explanation ==
We denote this notion of explanation by E1. Assuming some laws or theories relating to the physical domain as given (= accepted by the scientific community by and large) and referring to them as 'accepted theoretical notions', this might be put as follows:
== Phenomenal consciousness ==
We refer to these phenomena as 'phenomenal aspects of consciousness':
The key requirement for this definition of what is to be studied by a science of consciousness to make sense is to establish that there are aspects of experience which satisfy D1, i.e. which neither have a spatio-temporal structure nor a causal role in the production of behaviour. It is the second requirement with respect to which A1 is crucial, for A1 can be utilized to argue that nothing non-physical can have a causal influence on the physical domain.
== The goal of the scientific study of consciousness ==
It may be conjectured that what is to be studied in the scientific study of consciousness are, according to this grounding, phenomenal aspects of consciousness and their relation to the physical domain.
Since these are, by definition, not accessible to the usual scientific methodology, Chalmers proposes that the task of a science of consciousness is to find what he calls "sychophysical psychophysical laws"<ref name="mind" /> which relate the physical domain to phenomenal aspects of consciousness. Due to Assumption A1 and an underlying stance on the nature of causality
"[t]hese laws will not interfere with physical laws; physical laws already form a closed system. Instead, they will be "supervenience laws'', telling us how experience [= phenomenal aspects of consciousness] arises from physical processes"<ref name="mind" />. In combination with E1, this implicitly points at the major parts of the methodology to be used according to this proposal.
== Questions ==
Chalmers' grounding raises several questions related to the definition and ontological status of causality, to the validity of Assumption A1, to the nature of experiments in his grounding , and to the validity of the subsumed notion of explanation. There may be conceptual problems which that make it questionable whether a scientific research program based on this grounding can be carried out at all (cf. e.g. Appendix B in <ref>Kleiner, Johannes. "Mathematical Models of Consciousness." Entropy 22.6 (2020): 609.</ref>).
Furthermore, any scientific approach based on this grounding faces the question of which mathematical structure one is to use in order to describe phenomenal aspects of consciousness when formulating "psychophysical laws". Whereas the physical domain comes with a clear-cut mathematical structure, Chalmers' grounding merely asserts that the phenomenal aspects form a set and offers no systematic way of tying additional mathematical structure to the phenomenology of experience.
