Leibniz's 1695 essay — first public statement of the doctrine of pre-established harmony
New System of the Nature and Communication of Substances, as well as of the Union between the Soul and Body (Système nouveau de la nature et de la communication des substances, 1695) is Leibniz's first public statement of the mature metaphysical system that would later receive its fullest expression in the Monadology (1714). The essay introduces: substances as windowless monads, the pre-established harmony as the proper explanation of mind-body communication, the rejection of Cartesian interactionism and Malebranchean occasionalism.

School Embodiments
Major statement of continental-rationalist metaphysics — substances, pre-established harmony, sufficient reason.
"I found that substances cannot communicate with one another by way of physical influence; what we call communication arises from the harmony pre-established by the supreme cause." (New System)
Leibnizian-idealist commitments — monads as ultimate constituents of reality.
"The ultimate constituents of reality are simple substances — 'monads' as I shall later call them — endowed with perception and appetition." (New System)
Foundational text for the subsequent analytic-metaphysical treatment of substance, identity, and individuation.
"Each substance contains within itself the marks of its complete individual concept; this contains everything that can be predicated of it." (New System, anticipating later monadological doctrine)
Strong eternalist-temporal framework — each monad's development through time as the unfolding of its complete concept.
"What we call temporal development in a substance is the unfolding of what was already contained in its complete individual concept." (New System)
The pre-established harmony presupposes God as the substantial coordinator of all monads.
"The supreme cause has so arranged things from the beginning that what appears as causal interaction is the orchestrated unfolding of each substance's own internal nature." (New System)
Pluralist-substantival metaphysics — infinitely many real substances, each ontologically distinct.
"There are infinitely many substances, each unique, each containing its own complete concept of itself." (New System)
Natural-philosophical commitments — the system motivated by Leibniz's sense of the inadequacies of Cartesian and Malebranchean physics.
"The natural-philosophical phenomena require an explanation that Cartesian interactionism cannot supply; the New System offers that explanation." (New System)
Internal Tensions
The pre-established-harmony doctrine has been variously assessed — defenders see proper metaphysical-rationalist solution to mind-body communication, critics (Kant, modern analytic) see ad-hoc rescue of a system that need not have been entered.
