In the 19th century inhumanity meant cruelty; in the 20th century it means schizoid self-alienation.
Erich FrommThe two most far-reaching critical theories at the beginning of the latest phase of industrial society were those of Marx and Freud. Marx showed the moving powers and the conflicts in the social-historical process. Freud aimed at the critical uncovering of the inner conflicts. Both worked for the liberation of man, even though Marx's concept was more comprehensive and less time-bound than Freud's.
Erich FrommOur whole culture is based on the appetite for buying, on the idea of a mutually favorable exchange. .... For the man an attractive girl - and for the woman an attractive man - are the prizes they are after. 'attractive' usually means a nice package of qualities which are popular and sought after on the personality market. What specifically makes a person attractive depends on the fashion of the time, physically as well as mentally. ... Two persons thus fall in love when they feel they have found the best object available on the market, considering the limitations of their own exchange values.
