When considering the sciences and arts, a useful perspective that includes both wholistic and reductionist advantages is that of universal adaptation. This perspective is that everything may be viewed as being adaptive to varying degrees, from 0 to 100%, with typical cases being somewhere in between these extremes. And by "everything" we neccessarily have to include the boundaries and contexts that define anything. If this perspective seems objectionable for any reason(s), have patience for it will become clear later on why this perspective has many advantages when one is interested in creative, problem solving, analysis or related tasks.
input => interactive (adaptive) object => output
A classic systems theory view of such an object has a canonical form description as:
input =>(difference) => feed forward mechanism, H => output \\ // <======= feedback mechanism, G <======In the classic systems theory Laplace transform form:
In the classic logistic map form:
For the corresponding canonical recursive integrator (infinite impulse response low pass filter or IIR LPF), H(n) = b0 = constant and G(n) = -a1/b0 = constant:
For the unity DC gain version of this IIR LPF, b0 = 1-a1, for a1 being a parameter that has values of 0 (no adaptation) to 1 (infinite integration):
Examples of things often considered
As a concrete example,
There are advantages to view contexts as boundaries and vice versa. In doing so, there are two main points to make here regarding adaptability of boundaries:
