Freud was a nut. You can tell because he thought we were all nuts, and he considered himself typical (thus why he dismissed all claims to cocaine’s addictiveness, because he didn’t get hooked). So think of every odd trait Freud insisted everyone has (but you probably don’t, and most people clearly don’t) and understand Freud had them all. Still some useful and interesting insights into the human condition, but still a man with serious issues whose primary method of dealing with them was declaring they were normal.
