Enabling Constraint

#concept #stub2 mentions

An enabling constraint is a Constraint that creates alternatives:

constraints not only reduce the alternatives - they also create alternatives. Constraints, that is, can also create properties which a component exhibits in virtue of its embeddedness in a system, properties it would otherwise not have.Juarrero (1998), 234

But constraints also bias a constrained object towards reaching points and trajectories in the state space that would otherwise have been practically impossible or vanishingly unlikely.Winning & Bechtel (2018), 293
