Principle of Sufficient Reason and Reflection

As has been previously discussed, the object of the earliest Philosophy is a Principle of Sufficient Reason, which soon gets transformed into a transcendent Principle of Self-Sufficiency, the privileged term of a Dualism.  So, when Socrates introduces Reflection as a factor in Philosophizing, the most prominent and influential of interpreters of Socrates, Plato, incorporates that factor primarily by internalizing the Dualism.  It is not until Spinoza, inspired by Emanationism, rejects the Dualist transformation, and combines Reflection directly with a Principle of Sufficient Reason.  The combination consists in his conceiving the production of his own doctrine as itself grounded in the Principle of Sufficient Reason, his Insight into which is rendered as the Intuition of God in his doctrine.  Subsequently, the combination of Reflection and Principle of Sufficient Reason is most patently expressed by Marx and Nietzsche, who recognize their works as further consequences of a Principle of Sufficient Reason.  Otherwise, for the most part, Philosophical Reflection has remained as detached from its object as a transcendent Principle from some inferior realm.
