"... It does not lie in our power, Jung declares, to transfer 'disposable' emergy at pleasure to a rationally chosen object. On the contrary, the transfer is inevitably not only out of control, but also complementary to the conscious will; for, as Jung observes, quoting Heraclitus, who, as he says, was indeed a very wise man, 'everything tends sooner or later to go over into its opposite'.

The old Greek philosopher Heraclitus (c. 500 B.C.) called the process of psychological, historical, and cosmogonic overbalancing enantiodromia, 'running the other way'. And as an example of the process no better instance could be sought than that supplied by the two contrasting epics of Homer on which Heraclitus and his whole generation were raised: on one hand, the Iliad, with its world of arete and manly work and, on the other, the Odyssey, the long return, completely uncontrolled, of the wisest of the men of that heroic generation to the realm of those powers and knowledges which, in the interval, had been waiting unattended, undeveloped, even unknown, in that 'other mind' which is woman: the mind that in the earlier Aegean day of those lovely beings of Crete had made its sensitive statement, but in the sheerly masculine Heroic Age had been submerged like an Atlantis."
