From The Guardian:
Richard Bentall, a clinical psychologist, is a controversial figure in the field of mental health. An example of the hostility that his conclusions provoke among those practising conventional (that is, drug-based) psychiatry is given in the preface to this book, which raises serious questions about the treatment of mental illness. Bentall describes an encounter with an amiable-seeming psychiatrist who responds to a talk he has given as follows: “Professor Bentall has told us he is a scientist. But he is not! Nothing that Professor Bentall has said – not one single word – is true.”
The unlikelihood of a professor of psychology delivering, in the sober environment of an NHS conference, a talk in which every word is fictitious and every opinion fallacious gives a flavour of the threat that Bentall's theories pose. The response, as reported, sounds deranged and it is interesting to observe how debate among professionals over the causes of mental illness appears to induce its own version of madness, as if the topic itself were contagious. One sign of sanity, both in the individual and society, is the ability to deal with dissent.
In an earlier book, Madness Explained, Bentall was at pains to distinguish his approach from other anti-psychiatrists – for example, RD Laing, whose radical views were discredited because of his flamboyant lack of rigour and attendant inability to accept criticism. Bentall, as this book attests, is a different kettle of fish. With patient persistence and without recourse to rancorous diatribes, he has appraised the scientific evidence for the success of contemporary psychiatric treatments and come up with a dismal report. It is probably the very balance of his approach that drives his opponents crazy.
