In my epistemological system, thinking on the physicalist level is thinking not in terms of first-person experience, which is the ultimate foundation of knowledge, but on a higher level: in terms of physically existing people and things (past, present, and future). The physicalist level is built on the phenomenalist level.

That is, the physicalist level isn’t subjective but objective, isn’t about the mental experience of the physical (e.g., the colors, the smells), which is epistemologically primary, but about the physical itself.
