Anyone attempting to identify the thread that runs through the writings of the late Erich Fromm (1900-1980) will soon discover an unequivocally humanistic worldview. This was Fromm's guiding principle. From the 1930s on it signified his break with the Institute for Social Research, and marked his disputes with Marcuse, Horkheimer, and Adorno. Fromm himself frequently refers in his writings to the humanistic aspect of man: humanistic science, humanistic socialism, humanistic religion, humanistic psychoanalysis. This posthumous volume includes writings from one of Fromm's most fertile periods, the 1960s, during the last twenty years of his life. They are based on lectures, works written for specific occasions, and manuscripts intended as books. Of special interest is the extended essay on two very difficult thinkers, Meister Eckhart and Karl Marx.
