"Many are now skeptical of Freud’s theory – and of psychoanalysis in general – but the broad idea that the unconscious is in the driving seat has become widely accepted and has been given empirical support by contemporary research in psychology. Experimental psychologists might be less convinced by the primacy of Freud’s eros and thanatos – the sex and death drives – but they have catalogued a large number of biases and distortions of thought that affect each and every one of us. They may have abandoned Freud’s specific ideas but they have only added to the general picture of human nature he painted in which we are not so much rational as rationalisers, using reason to make sense of our beliefs and actions after the event. Must we therefore accept that reason is a mere veneer for irrational impulses, or can can psychology justify giving rationality an important role in human thought and judgement?"
