the-under normal conditions-merely compensatory function of the unconscious becomes a guiding, prospective function capable of leading the conscious attitude in a quite different direction which is much better than the previous one
This is Jung’s canonical definition of the prospective function, specifying that it emerges when the individual’s conscious attitude is sufficiently unadapted, transforming the normally compensatory unconscious into a teleological guide.
