Part of the relationship of complexity to values is that we understand by making patterns. If we are seeking understanding before judgement, then we need to see enough action to make sense. I include linguistic action in all action. And, given that we will have to speak about it to make very complex value judgements, the liguistic portion of the structure will be high and important. Behaviour is a pattern of action.
Practices are patterns of action.
The difference is that the first has psychological roots and the second has ontological roots. That provides the possibility of direct access to practices. Intelligence is the underlying organisational principle of the universe.
