If you accept that (1) cognition (including language) is best explained by recursively applied symbolic rules and (2) physical reality is best explained as a manifestation of recursively applied computational rules, then it logically follows that *both* mind and matter can be seen as “threads” in a unified, generative network of rule-based processes. Thus, they are *not* separate substances or phenomena but rather co-emergent aspects of one recursive fabric.
They are part of a *multi-level causal interplay*: the physical level enables the rule to be carried out, while the rule *constrains* the organization of those same physical processes.
