This book offers a challenging alternative to what many will believe without question; that is, that we are free souls with inner agents and thoughts that guide our behaviour. This fine introduction to the behaviorist position offers the opposite view. It states, very simply, that behavioural responses are learnt through interaction with environmental stimuli and that behaviour is determined and not free at all. Skinner also attempts to address some of the commonly held myths surrounding the philosophy of behaviorism such as there is no place for the self or that thinking should be disregarded. As a radical behaviorist Skinner simply states that thinking is internalised behavior shaped by the same contingencies of reinforcement as other learnt responses. Now that's something interesting to think about!
