Answer
Sigmund Freud, the father of psychoanalysis, was deeply influenced by Ludwig Feuerbach's philosophical and anthropological ideas. Feuerbach's critique of religion, his emphasis on human nature and self-awareness, and his materialism greatly shaped Freud's thinking. Freud adopted Feuerbach's notion of projection, recognizing that our beliefs and values are influenced by our own experiences and desires. This concept became central to Freud's theory of the unconscious mind.
