THIS BOOK WILL EXPLAIN WHAT MADNESS IS, TO SHOW THAT IT CAN BE
UNDERSTOOD IN PSYCHOLOGICAL TERMS, AND THAT BY STUDYING IT WE CAN LEARN
IMPORTANT INSIGHTS ABOUT THE NORMAL MIND. THE BOOK WILL ARGUE THAT
TRADITIONAL APPROACHES TO MADNESS MUST BE ABANDONED IN FAVOUR OF A NEW
APPROACH WHICH IS MORE CONSISTENT WITH THAT WE NOW KNOW ABOUT THE HUMAN
MIND. OVER THE LAST CENTURY OR SO IT HAS BECOME SO COMMONPLACE TO REGARD
MADNESS SIMPLY AS A MEDICAL CONDITION THAT IT HAS BECOME DIFFICULT TO
THINK OF IT IN ANY OTHER WAY. BENTALL ARGUES INSTEAD THAT DELUSIONS,
HALLUCINATIONS AND OTHER UNUSUAL BEHAVIOURS ARE BEST UNDERSTOOD
PSYCHOLOGICALLY, AND THAT SUCH EXPERIENCES FOR THE MOST PART REPRESENT
EXAGGERATIONS OF MENTAL FOIBLES TO WHICH WE ARE ALL PRONE.
