One of the problems of the machine assumption about systems and the barrier assumption about constraints is that they fail to realize the possibilities that constraints in a CAS have as points of initiating change. In a CAS various constraints act as potential points of leverage. Physical and Occupational therapists understand this concept of leverage as a deep part of their professional learning and work.
In a machine, a point of constraint has a single or a small number of potential uses as leverage. In our bodies, and in CAS generally, points of leverage operate in a Possibility Space, so that many currently unrealized uses of leverage are possible. This possibility space in us also involves our brain.
If you remember the discussion of how infants develop in a possibility space, you will remember that there is a lot more to development than the acquisition of a skill outcome. At every step, every experience of the child contributes to the development of the child’s ability to engage the possibility space. They also create new relationships with that space and what/who is in it, so the possibilities of the space expand as a direct result of developmental action.
Here, that means that using leverage and learning from its use enlarges the possibilities in the space and constitutes a core of what an enabling relationship means.
We need to internalize the idea that constraint=leverage by reflecting on the possibilities of any constraint we find in our work,.
