Knight points out that people who feel driven to intimidate others are usually defending themselves against anxiety. These people have a strong need for love which they are unable to admit. Their aggressive attitude provokes hostile responses which increase their anxiety and consequently the need for more aggressive behavior. Thus a vicious cycle is established which can only be broken by analyzing the anxieties. In a very interesting case Knight brings out the decisive factors which produced anxiety by analyzing the transference resistance. The patient, who came to treatment in a catatonic excitement, belonged to this group of belligerent personalities. The deeply repressed passive homosexual longings were the decisive factor in the illness.
