I’ve been a Szasz since 1978. Have gotten into several arguments, especially with school social workers because of it.
Basically, people either have an organic issue, which with fMRI’s is getting easier to find, or thy have learned inappropriate behavior.
There is no such thing as ‘mental illness”
It ain’t rock science, just common sense.
My father has a similar opinion. The brain can be ill, but the mind is not a physical organism subject to illness.
