Many forms of nostalgia and longing signify no more than a return to uroboric incest and self-dissolution, from the unio mystica of the saint to the drunkard’s craving for unconsciousness and the “death-romanticism” of the Germanic races. The incest we term “uroboric” is self-surrender and regression. It is the form of incest taken by the infantile ego, which is still close to the mother and has not yet come to itself; but the sick ego of the neurotic can also take this form and so can a later, exhausted ego that creeps back to the mother after having found fulfillment.
