ABSTRACT
H. J. Eysenck provokes and, seems to relish controversy. Since Eysenck is an excellent controversialist and can turn in a much better wounding phrase, a neater intellectual insult, than most, such a reasonableness can be infuriating. He admits that he enjoys opposing other people's ideas. Eysenck seems very sensible and moderate in advocating a kind of integration of psychology, physiology, genetics and biochemistry. Eysenck, also rather surprisingly, derides the mania for prediction. He certainly thinks that prediction is important. And, as Eysenck believes in the need for psychology, physiology and other biological sciences to co-operate in the strongest ways possible, he thinks that the borderlines between these disciplines can be especially fruitful in ideas which one cannot often hope to be particularly strong but which, with patience and with work, can yield valuable results. Psychologists who want that gloss of rigour tend to avoid precisely such areas.
