Summary

German philosopher and mathematician who invented calculus independently, developed monadology — the view that reality consists of simple, immaterial, windowless monads — and argued this is the best of all possible worlds.

Core Contribution

Monadology: reality consists of simple, immaterial, indivisible substances (monads) with no real interaction — only pre-established harmony established by God. This is the best of all possible worlds (optimism). Invented calculus independently of Newton. The principle of sufficient reason: everything has a reason.

Key Spikes & Highlights

The Newton-Leibniz calculus priority dispute was the bitterest scientific controversy of the early 18th century — Leibniz was posthumously tried by the Royal Society (presided over by Newton) and found guilty.
Each monad is a mirror of the entire universe from its own perspective — the best of all possible worlds is the one God chose because it contains the greatest variety of phenomena from the simplest laws.
Voltaire's Candide is a sustained satirical attack on Leibnizian optimism — the best of all possible worlds, after Lisbon and Auschwitz, became a philosophical punchline.
