Synopsis of Aesthetic Theory Aesthetic theory governs the developement and behaviour of planetary biologic systems beginning with an abstract premise and terminating in art. Whole planets are each individually governed by their own distinct harmonic systems of vibrational (or, structural) aesthetics which applies to the expression of mechanistic nature. The epitomy of planetary evolution--the thinking people (or, homo-sapiens) of their planets have the added luxury of expessing their impulses in an artistic manner: art, music, sculpture, dance, architecture; but governed by the same aesthetic theory of form. Mother nature would also be doing her own laboratory experiments in applied biology involving: organic chemistry, botanical structuring, humaniod neural behaviour, etc. This is to be distinguished from: individual concerns such as the humanities, i.e., literature, religion, politics, theatre, etc.; or, pure science studied at a level before it reaches application. Application of the laws of nature require aesthetic form to guide their behaviour. Science normally studies mechanics of operation while leaving choices among options, during nature's operations, open to question---are they naturally selected, randomly stumbled over, ...? This aesthetic theory provides that at least some of those questions when they arise have already been determined by an unknown decision reached by nature in a manner more mysterious than even mechanistic theory can explain.
