The strong feeling-tone, then, creates a path, which amounts to saying what we have already said about complexes.
Every complex has a tendency to autonomy—to act itself out independently; it has a greater tendency to persistence and reproduction
than ordinary, indifferent thought and so has a better chance of becoming automatic.
Hence, when something becomes automatic in the psyche an antecedent feeling-tone must be postulated.
The clearest example of this is hysteria, where all the stereotypies, such as attacks of cramp, trance-states, complaints, and symptoms, can be traced back to the underlying affects.
In the normal association experiment we usually find perseveration where the complex is located. ~Carl Jung, CW 3, Para 183
