All psychiatrists agree that schizophrenia is a severe mental disorder, a condition where the normal order of thinking has been impaired. A return to orderly thinking is the way forward to healing ones mind. Common symptoms of schizophrenia include delusions, including paranoia and hallucinations, and disorganized thinking patterns. Schizophrenia is a widespread affliction. Its has a world-wide provenance and has little regard for social class.
Your brain is divided into two cerebral hemispheres that are only loosely connected via a bundle of nerve fibers. We are taught that we only have one brain but that is not necessarily exactly true: we have two slightly asymmetric brains that communicate with each other, may disagree frequently and sometimes one brain overrules the other one.
I (and some others like Alfred de Grazia) believe that man is born schizophrenic. Only nurture and playing with his peers will eventually result in some level of saneness. But that is only a thin veil and rates of schizophrenia always rise with rising social disorganization.
So, say goodbye to the sane Homo Sapiens and entersay hello to Homo Schizo.
