First, Darwinian theory tells us how a certain amount of diversity in life forms can develop once we have various types of complex living organisms already in existence.
Also, since art is a vehicle for the transmission of ideas through form, the reproduction of the form only reinforces the concept. It is the idea that is being reproduced. Anyone who understands the work of art owns it. We all own the Mona Lisa.
The great charm and comfort of the system is, that its affects are palpable within a week of trial, which creates a natural stimulus to persevere for few weeks more, when the fact becomes established beyond question.
