Fields can be combined by nesting them, or stacking them, or adjoining them, or doing the virtual equivalent of connecting them with wires.

The feedback loop is a difficult structure. Computer programs normally deal very poorly with feedback loops. Surely the feedback loop is one of the most fundamental structures of nature. The idea of a poem which folds back on itself at the end is a venerable one, one of the classic ways to end a poem. In the network way of thought, a thought itself is a network, down to a fine grain.
