In fact, there are very important writings of Marx which are not even translated into English.
Erich FrommAll great art is by its very essence in conflict with the society with which it exists. It expresses the truth about the existence regardless of whether this truth serves or hinders the survival purpose of a given society. All great art is revolutionary because it touches upon the reality of man and questions the reality of the various transitory forms of human society.
Erich FrommLove is active penetration of the other person, in which my desire to know is stilled by union. In the act of fusion I know you, I know myself, I know everybody - and I "know" nothing.
Erich FrommFor [Karl] Marx it is socialist society which realizes "concretely" the religious principles of equality, brotherly love, and freedom.
Erich FrommI am convinced that boredom is one of the greatest tortures. If I were to imagine Hell, it would be the place where you were continually bored.
Erich FrommModern man has transformed himself into a commodity; he experiences his life energy as an investment with which he should make the highest profit, considering his position and the situation on the personality market. He is alienated from himself, from his fellow men and from nature. His main aim is profitable exchange of his skills, knowledge, and of himself, his "personality package" with others who are equally intent on a fair and profitable exchange. Life has no goal except the one to move, no principle except the one of fair exchange, no satisfaction except the one to consume.p97.
