Leon Eisenberg quotes:

ADHD is a prime example of a fictitious disease.

Psychiatry is all biological and all social. There is no mental function without brain and social context. To ask how much of mind is biological and how much social is as meaningless as to ask how much of the area of a rectangle is due to its width and how much to its height

The university is the last remaining platform for national dissent.

To believe that man's aggressiveness or territoriality is in the nature of the beast is to mistake some men for all men, contemporary society for all possible societies, and, by a remarkable transformation, to justify what is as what needs must be; social repression becomes a response to, rather than a cause of, human violence. Pessimism about man serves to maintain the status quo. It is a luxury for the affluent, a sop to the guilt of the politically inactive, a comfort to those who continue to enjoy the amenities of privilege.
