The Orc-Urizen cycle

From The Anti-Teleological Dialogism of the Imagination in William Blake’s The Marriage of Heaven and Hell by Steven M. Streufert.

As these states are cyclic, not linear or mutually exclusive, so are they constantly reflective of one another, discursive and commingling. This cycle repeats itself throughout Blake's work, arising most notably and significantly as the Orc-Urizen cycle, wherein no rational ordering of the universe can exist for long at the expense of rampant energy without giving rise to new generative and imaginative profusions. No telos may long stand, as with any other trope or passing fashion. These made meanings feed upon one another, need one another, as they continuously reconstitute the very fabric of both organic reality and human society and understanding. The result is best represented by and understood as a fugue, a melding of seeming opposites in a complex, higher order of being within which forces and states of being are collaborative and mutually informative.
