From my studies it just sounds like people didn’t like how authoritative Freud was. Which is funny given the line about the necessity for a confident doctor leading to positive outcomes. Jung even had a falling out with him. But the author is also a neurosurgeon, quite a brilliant one at that. It sounds like a cyclical review in itself. Almost like a modern version of the exact book he is reviewing given his own relationship as a neurosurgeon potentially being forgotten alongside Freud.
Great article!
