Full Idea
Any attempt to say what behaviour follows from a given state of mind can be shown to be false by producing an example in which the state of mind is present but, owing to the addition of new beliefs and desires, the behaviour does not follow.
Gist of Idea
No mental state entails inevitable behaviour, because other beliefs or desires may intervene

A Reaction
The objection seems misplaced against eliminative behaviourism, because there are held to be no mental states to correlate with the behavior. There is just behaviour, some times the same, sometimes different.
