On the Mad Seer.

Too often, the seer is  condemned to the Fate of Madness. Yet this is not a mental state, at least not at the outset, but a legal state. Insanity is not a medical term, but a legal term. Medical terms include neurosis and psychosis. Yet one would seldom be mistaken in the identification of a Psychotic. Yet the few times this does happen it is itself a grave neurotic symptom. Usually, the psychotic himself is either terrified by his sudden divorce from Civilised Reality or past the will and ability to express himself. Yet even then, a refusal to make one's self 'understood' in a comfortable, conventional way can at best be guessed to be a symptom of a lack of will; one may be Able but not willing.
Yet that is apparently illegal. Is it for this reason that the psychotic is Insane? Is it only for this reason?

The neurotic, definitionally, is one who is unaware of a personal problem. The Seer is one who becomes aware of an External problem.
Yet who can fairly draw a line betwixt the internal and the external, nor between Fact and illusion, if all 'Reality' is perception? If our perceptions are filtered by culture, we require Seers to glimpse, sometimes with Terror, those things which brew underneath the surface of our common self-flattery. To speak in religious allegory, we need to See things which are only shown to one person at a time.
