The map is not the territory. Maps can be more or less accurate, and more or less easy to use. The question is whether the map helps me get where I want to go, or leads me astray. Dualism or monism are two different structural commitments. What does each buy, and what do they cost?

Philosophical schools are approaches not positions

Yep. A map is a means to get somewhere.
