Nature, Thought, Intelligent Design

Spinoza's concept of Nature is of a dynamic, creative Substance.  Hence, more accurate than 'Thought' and 'Extension' as terms for its attributes, likely references to Descartes' static substances, are 'Thinking' and 'Extending'.  Now, one way to understand what he means by the attribution of Thinking to Nature is to examine an exemplification, i. e. the Thinking of a Mode as it creates.  So, his description of the guiding of the drawing of a circle by following the definition of a Circle is one such example.  On that basis, more generally, any production, guided by a model, whether of a sequence of behavior, or of the manufacture of some thing, exemplifies the Thinking of Nature.  Accordingly, his attribution of Thought to Nature is equivalent to the attribution of what might be called  'intelligent design' to Nature, though, quite contrary to the usual use of that phrase, the design is a product of immanent designing, i. e. is the self-designing of Nature.
