Psychosis (n.) can ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠be beautiful, a schizophrenic girl told Jung, hating him for barring her from hers, a reminder that madness can hold ecstasies and adventures that tempt patients back.

Psychosis (n.) is, ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠psychologically speaking, a state in which formerly unconscious elements take the place of reality, which happens when people lose their hold on life's concrete values.

Schizophrenia (n.) deserves ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠a square deal for its psychic side, Jung demanded, since biology, anatomy and physiology had had all the attention and still knew little of heredity or the primary symptom.

Schizophrenia (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠Bleuler's "split mind", which for Jung has a psychology with causes and aims like normal life, except that the ego is only one of several experiencing subjects, the person split into a plurality of autonomous complexes.

The Toxin hypothesis (n.) Jung ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠returned to late in life: emotion exceeding the capacity of brain-cells might cause a local organic disintegration, a view encouraged by experience with mescalin.

The Toxin hypothesis (n.) was ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠Jung's tentative 1906 guess that the affect in dementia praecox might trigger metabolic poisons injuring the brain, so the last complex "coagulates" and further development halts; a primary physical change could not be excluded.

Affectivity (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠the essential basis of personality, Jung held; thought and action are, as it were, only its symptoms.

Alcoholic jealousy (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠an unconscious compensation: the drinker's love for his wife has not vanished but sunk below the threshold, and can return only as jealousy.

Belle indifférence (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠the smiling calm with which hysterics describe what should move them deeply; the autonomous complex lets itself be reproduced only when it wishes, so the mask breaks suddenly in a storm of affect.

A Complex (n.) stands ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠in relative independence from the ego, a vassal that will not give unqualified allegiance; its associations come only with struggle, slip away, and fall into amnesia, while indifferent ones come smoothly.

A Dream (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠the hallucination of normal life, nothing but a hallucinatory representation of repressed complexes.

Insanity (n.) is, ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠literally and not as metaphor, a dream that has become real and replaced waking consciousness; the dreamer is normally insane, and the phenomenology of dream and schizophrenia is almost identical.
