Delusional intuition

A phenomenological understanding is of an occurrence that is very much like the expression of the spontaneous occurrence of an inspirational idea, sprung from the soil, translated into a delusionary vehicle with the conviction of "immediate enlightenment" (Leon et al 1989) that occurs as a delire d'embléé i.e. complete in the actual instance. The delusion as defined autochthonous in this context is known as primary (Jaspers 1963).

Occurrence
The delusion is found described in clinical settings as a description of medical symptom of the psychotic illness known as schizophrenia, and is known within that milieu as a first rank symptom The delusional ideation sometimes occurs from a prior delusional mood (Fish 1985). According to the Klaus Conrad 1958 account, grātia gratiam parit, the delusion occurs as a second order development of earlier delusionary thinking.
