Rudolf Arnheim moves in Entropy and Art from describing to prescribing. Capture the reader by the move from a description of an artefact to a description of values and principles. Spot the reader a drink, saddle up a pony.
The structural theme must be conceived dynamically, as a pattern of forces, not an arrangement of static shapes.
And back again to description:
These forces are made visible, for example, by the confluence of the large folds in the Madonna’s garment which lead to the hand supporting the child.
Dynamic-static decomposes fast when inertia is considered as speed. Pattern-arrangement seems to play with the repeatable and the unique or the specific. Pattern unlike arrangement is multifocal. Arrangements are always on the way to pattern. Force shape. Shape force.
And so for day 60
