To be constrained, and the constraint.

For a system to be useful it must have constraints. For example a system of N degrees of freedom can be represented in an N dimensional space, however without constraints it occupies that whole space.

The problem is the opposite for a system that is seeking to express itself. It needs freedom from constraints so that it may be large enough to contain all possibilities. The N dimensional space is the ideal system in which to express other systems because it is free from all constraints other than its dimensionality.

For a system to express itself it needs to have less constraints than itself. If it has the same constraints as itself then isn’t its representation the same as itself?
