There is part-whole physicalism, that everything is exhausted by basic constituents that are themselves physical, or supervenience or levels physicalism, that the putatively non-physical is dependent on the physical.

A Reaction
The cite Hüttemann and Papineau 2005. I am not convinced by this distinction. Ladyman and Ross oppose the first one. I'm thinking the second one either collapses into the first one, or it isn't physicalism. Higher levels are abstractions.
