Abstract
One foundation of Eliminative Materialism is the claim that the totality of our ordinary resources for explaining and predicting behaviour, ?Folk Psychology?, constitutes a theoretical scheme, potentially in conflict with other theories of behaviour. Recent attacks upon this claim, as well as the defence by Paul Churchland, are examined and found to be lacking in a suitably realistic conception of theory. By finding such a conception, and by correctly identifying the level of conceptual structures within which Folk Psychology is located, the original claim is reinforced
