Action explanations that cite dynamic beliefs and desires cannot be modelled as causal explanations. The contents of dynamic psychological states cannot be treated as the causal antecendents to behaviour. Behavioural patterns cannot be explained in virtue of the patterns of operations performed upon the intentional antecedents to behaviour. Dynamic intentional states are persisting regulatory devices for behaviour that provide couplings with the environment. Behavioural patterns emerge from choice couplings rather than being produced by patterns for operating upon intentional antecendents to (...) behaviour in cognition. (shrink)
