Discourse on schizophrenia

In one of RD Laing's books - RD Laing quotes Marx and lays forth a postulate....

he argues that under ONLY certain specific social and economic circumstances is a black person (or anyone) a slave...

in the 1800's an African (or African American) would only be a slave if they were under certain SOCIAL and ECONOMIC circumstances in the South... but in the NORTH they would be FREE....

Laing puts forth that similarly... under only CERTAIN social and ECONOMIC circumstances will a human be a SCHIZOPHRENIC .... however... anyone can go on a journey in their mind, so to speak....
