12 aspects of economy

In line with the recent 'The Ternary Classification' post, another quartet can be added to the two quartets of the 'Eight Aspects of Economy' post of 2010;

(((Gather, Hunt), (Farm, Manufacture)),

((Information, Intelligence), (Imagine, Create)),

((Barter, Trade), (Commerce, Finance)))

as the Application layer to complete the classification. I renamed the (Spiritual, Artistic) duality to (Imagine, Create). This way, the first quartet becomes the Measure, and the second the Theory of the ternary foundational classification. In the economics context, the first and third element can be called Production and Exchange.
