The Psychological Implausibility of Naturalized Content

Conceptual Atomism (CA) is the view that psychological concepts are a toms (no internal structure, no n ecessary relations to o ther concepts). CA is a psychological/semantic theory. I show that CA has become mixed up with a separate, meta-semantic project t hat seeks to n aturalize c ontent, and that this Naturalized Conceptual Atomism has ended up in the self-defeating position of positing non-atomic structures for a large number of concepts. The solution is to separate the two projects again, and allow them to develop on their own.
