Freud Turns On Himself

Was the concept of God that Freud rejected determined by his relation to his father?

And was Freud's atheism also determined by that relationship, instead of his alleged universalities of human nature?

After all, Freud himself said that his views applied to all human theorizing.

Material Needs Determine Materialism

MARX: Every aspect and thought is determined by social and economic factors. Material needs determine everything. Ideas and values are determined by the material realities of life. Material reality is the foundation on which the superstructure of ideas is erected. Hence, people's social and economics conditions determine what they think.

ME: What material needs and realities determined that theory itself?
