The term schizophrenia has come to have so many contradictory meanings and implications. What is schizophrenia?

For me, almost the one certain thing about ‘schizophrenia’ is that it is a diagnosis, that is, a clinical label, applied by some people to others. Until recently, this label meant that the labeller was under the impression that the behaviour of the person he was labelling was symptomatic of some pathological process, itself of unknown nature and origin, going on in the body of the person. This view could be held together with the view that the pathological process was also, primarily or secondarily, a psycho-pathological one, going on in the psyche of the person. In any case the label had one connotation. The person labelled was not like us.

While this view has been at its height in the last quarter of a century, psychiatrists have become so possessed by it that this entirely hypothetical pathological process has ceased to be an assumption and has become a fact. Almost no one quite realized that the ‘process’, somatic or psychic, had never actually been discovered. The diagnosis tended to be made more frequently among members of the same kinship groups, and this seemed to support the view that the persons labelled possessed some inherited factor in common with each other, but not with the labellers, and this explained why they were being so labelled.

Briefly, the present position can be stated to be that recent critiques of the work on genetics, and the most recent empirical genetic studies, have alike brought all the apparent advances in this field back to square zero, while biochemical research is still inconclusive.

There now appears to be no substantiated evidence that these labelled persons have any constitutional factors in common with each other, that they do not have with us. It would now be an interesting experiment to study whether the syndrome of ‘labelling’ others runs in families. A pathological process called ‘psychiatrosis’ may well be found, by the same methods, to be a delineable entity, with somatic correlates, and psychic mechanisms, with an inherited or at least constitutional basis, a natural history, and a doubtful prognosis.
