Emanation, Evolution, Geometry

If, as Wolfson interprets it, Spinoza's doctrine is Emanationist, then his God/Nature/Substance begins as absolutely simple, and infinitely develops in complexity.  Thus, the doctrine can also be classified as Evolutionist, e. g. one event in which is a development in the complexity of the thumbs of some simians.  Now, according to Spinoza's Parallelism, all Ideas are fundamentally actual, i. e. correspond to some Body or another.  But, if so, his concept of Eternity is problematic when attributed to Ideas, for that attribution entails that an Idea might pre-exist its corporeal actualization.  More specifically, insofar as he defines a Circle in terms of how to draw one, the Idea of a Circle cannot be eternal, since a corporeal Circle cannot pre-date the evolution of the Mode with the bodily capacity to execute the definition.  Instead, on the basis of the premises of his doctrine, the Circle, and all figures that must be drawn, i. e. Geometry, must be a concomitant of Evolution.  In other words, in an Emanationist doctrine, as an in an Evolutionist theory, the idea of Geometry is no more eternal than Species are fixed.
