To Have or to Be?

To Have Or To Be? is regarded as one of the seminal books of the second half of the 20th century. This book is a summary of the penetrating thought of Erich Fromm. His thesis is that two modes of existence are struggling for the spirit of humankind: the having mode; and the being mode. Fromm explains why the having mode is taking the world to the brink of psychological and ecological disaster.
