Deutero-learning

Learning to learn. Bateson's hierarchy: Learning 0 (no change), I (a change of response within a set), II (a change of the set itself), III (a change in the way sets are formed) — which he thought rare and destabilising.

Level II is where "character" lives, and where therapy actually operates. Level III is Bateson's own name for what Wilson would call leaving Chapel Perilous.
