First Published in 1998. This is Volume IV of eighteen in the Sociology of Behaviour and Psychology series This is a study of social isolation, plus its causes. Written in 1952 rather than just ask what is wrong with the state of the world today, Dr Halmos turns to scientific analysis, constructive criticism and positive suggestion has he passes from study of basic social forces, through historical and empirical investigations, to the practical problems of reform and therapy. He has penetrated below the facile generalisations of common experience by distinguishing between neurotic types -the anxious, the depressed and the hysterical-and studying the different ways in which each is related to social isolation or participation.
