The Leibniz-Clarke Correspondence
Leibniz's 1715-16 final philosophical correspondence with Samuel Clarke (representing Newton) — the founding text of modern philosophy of space, time, and divine action
Tradition: Early modern philosophy of physics
Leibniz's 1715-16 last philosophical work — the founding debate over space, time, and divine action between relationalist and absolutist physics
The Leibniz-Clarke Correspondence (1715-16) is Leibniz's final philosophical work — an exchange of 5 letters with Samuel Clarke (representing Isaac Newton). The debate addresses: the metaphysical status of space and time (Leibniz's relationalism vs. Newton's absolutism), the proper conception of divine action in the world, the principle of sufficient reason, the identity of indiscernibles. Founding text of modern philosophy of physics and the locus classicus of the relationalism-vs-absolutism debate about space and time.

School Embodiments
Paradigm rationalist principles — sufficient reason, identity of indiscernibles — applied to physics.
"If space were absolute, God would have had no sufficient reason to place the world here rather than two feet to the side." (Leibniz to Clarke, Third Letter)
Leibniz's relationalism about time has been foundational for relationalist philosophy of time.
"Time is the order of successions; space is the order of coexistences." (Leibniz to Clarke)
The relational theory treats space-time as ideal-relational, not substantival.
"Space and time are not substances but relations of substances." (Leibniz to Clarke)
Foundational text of analytic philosophy of space, time, causation.
"The principle of sufficient reason — that everything has a sufficient reason for being as it is — is the foundation of all metaphysics." (Leibniz to Clarke)
Debate over divine action — Clarke's "world-machine that requires periodic intervention" vs. Leibniz's "perfectly designed machine."
"Whoever maintains that God periodically intervenes in the world-machine impugns His wisdom." (Leibniz to Clarke)
Realist about substances and relations; the relational theory does not reduce space-time to mere convention.
"Relations are as real as the substances they relate." (Leibniz to Clarke)
Internal Tensions
Einstein's general relativity has substantially vindicated relationalism about space-time; contemporary debate (Earman, Maudlin) continues. The Leibniz-Clarke exchange is the founding moment.
