You should consider his thoughts in the time he wrote them. His broad point of view is mainstream today. His specific methods are not. In the early 70s his way of thinking was new. Consider Sigmund Freud and his wild theories. Almost everything he did is now considered wrong today. His only lasting impact is popularizing the idea of unconsciousness. The idea of unconsciousness desires, needs, and thoughts affecting our life so mainstream today it's hard to comprehend that it was not in the conceptual toolbox in the west before him. (Friedrich Schelling predated Freud but his works were largely ignored during his time)
