Introspection tells us: There are thoughts, sensations, and emotions and these are not electrochemical impulses in a neural network.

Therefore, the theory that says that thoughts, sensations, and emotions are electrochemical impulses in a neural network (reductive materialism) is mistaken.

Churchland's reply:

In external senses (e.g. vision) we discriminate "intricate electromagnetic, stereochemical, and micromechanical properties of physical objects" without knowing we are. So also in introspection.
