ABSTRACT
Materialists deny that the world includes both mental and material substances. Every substance is a material substance. Minds are fashioned somehow from the same elementary components from which rocks, trees, and stars are made. If we take the fundamental particles that make up inanimate objects and arrange them one way, the result is a granite boulder; differently arranged, the outcome is a creature with a mind. The mind is not a separate, nonmaterial entity, but only matter, suitably organized.
