Some metaphysics are provided showing that what is commonly called ‘the physical world’ can be deconstructed into three ‘levels’: a single, unified ‘noumenal world’ on which everything supervenes; a ‘phenomenal world’ that we each privately experience through direct perception of phenomena; and a ‘collective world’ that people in any given ‘language using group’ experience through learning, using and adapting that group’s language. This deconstruction is shown to enable a clear account of qualia and of how people can hold some things to be physically real even when it is clear no one can ever directly experience those things as phenomena. It is further shown to enable a single, internally consistent, largely empirically supported conceptual framework – a ‘metacosmology’ – able to encompass not only the physical world as people conceive of it for everyday purposes, and as scientists conceive of it for scientific purposes, but also people’s first person phenomenal experience of a physical world and, prospectively, the mechanisms by which such first person, conscious experiences can be generated.

This is Appendix B to the note, Deconstructing the Physical World (DPW). This appendix extends DPW to provide a set of new conceptual tools able inter alia to deliver a systematic, well-structured and highly novel set of insights into: core aspects of how language learning and use might work; what precisely is going on in inverted qualia thought experiments and in relation to the knowledge argument; and how incorporating differentiated forms of qualia into some fundamental ideas about language learning and use can help more clearly define what we mean when we refer to such things as ‘concepts’ and ‘imagination’.
