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’.
