Marvin Minsky on Sigmund Freud

“At one time, many philosophers held that faultless "laws of thought" were somehow inherent, a priori, in the very nature of mind. This belief was twice shaken in the past century; first when Russell and his successors showed how the logic men employ can be defective, and later when Freud and Piaget started to reveal the tortuous ways in which our minds actually develop.”

“Each child makes "internal models" that help them predict their Imprimers' reactions... as an "internalized" system of values—and this could be how people develop what we call ethics, conscience, or moral sense. Perhaps Sigmund Freud had such a process in mind when he suggested that children can "introject" some of their parents' attitudes.”

“Much research in psychology has been more concerned with how large groups of people behave than about the particular ways in which each individual person thinks... too statistical. I find this disappointing because, in my view of the history of psychology, far more was learned, for example, when Jean Piaget spent several years observing the ways that three children developed, or when Sigmund Freud took several years to examine the thinking of a rather small number of patients.”

“How much of a person's competence is based on knowing which actions not to take? We usually think of a person's abilities in positive terms... But one could take the opposite view that "An expert is someone who rarely slips up—because of knowing what not to do." However, this subject was rarely discussed in the twentieth-century—except, perhaps most notably, in Sigmund Freud's analysis.”

“Sigmund Freud's early view of the mind [is] as a system for dealing with conflicts between our instinctive and acquired ideas.”
