ned him, as well it should. So again, he wanted to understand something irrational -- the irrationality of mass behavior -- and he found some answers, this time in the writings of Karl Marx. 8To finish Fromm's story, he received his PhD from Heidelberg in 1922 and began a career as a psychotherapist. He moved to the U.S. in 1934 -- a popular time for leaving Germany! He then settled in New York City, where he met many of the other great refugee thinkers that gathered there, including Karen Horney, with whom he had an affair. 8Toward the end of his career, he moved to Mexico City to teach.

In other words, Freud postulated that our characters were determined by biology. Marx, on the other hand, saw people as determined by their society, and most especially by their economic systems. He added to this mix of two deterministic systems something foreign to them: The idea of freedom. He allows people to transcend the determinisms that Freud and Marx attribute to them. In fact, Fromm makes freedom the central characteristic of human nature.There are, Fromm points out, examples where determinism alone operates. A good example of nearly pure biological determinism, ala Freud, is animals (at least simple ones). Animals do not worry about freedom -- their instincts take care of everything. Woodchucks, for example, don't need career counseling to decide what they are going to be when they grow up: They are going to be woodchucks.A good example of socioeconomic determinism, ala Marx, is the traditional society of the Middle Ages. Just like woodchucks, few people in the Middle Ages needed career counseling: They had fate, the Great ...
