public sculpture 1

Correlatively, the formation of the I is symbolized in dreams by a fortress, or a stadium - its inner arena and enclosure, surrounded by marshes and rubbish-tips, dividing it into two opposed fields of contest where the subject flounders in quest of the lofty, remote inner castle whose form (sometimes juxtaposed in the same scenario) symbolizes the id in a quite startling way. Similarly, on the mental plane, we find realized the structures of fortified works, the metaphor of which arises spontaneously, as if issuing from the symptoms themselves, to designate the mechanisms of obsessional neurosis - inversion, isolation, reduplication, cancellation and displacement.
