Gottfried Leibniz
Leibniz tried to prove that reality is not a random heap of facts but a rational order—one in which even loss, conflict, and contingency can be read as parts of the most intelligible world God could have made.

Timeline
Birth of Leibniz
**1646-07-01** — Leibniz was born in Leipzig in 1646, near the end of the Thirty Years’ War. The political and confessional devastation of central Europe formed the background against which his lifelong search for intellectual and social reconciliation took shape.
University Studies Begin
**1661** — Leibniz entered the University of Leipzig and immersed himself in logic, law, and philosophy. The academic world he encountered still bore strong scholastic traces, but he was already moving toward a broader synthetic vision.
Publication of the New Method in Law
**1666** — His early legal work, including "De arte combinatoria" and related writings, revealed the direction of his intellectual life: the search for a formal method capable of organizing thought and dispute. These texts already hint at his dream of a universal calculus.
Paris Sojourn
**1672** — Leibniz traveled to Paris, where he encountered leading mathematicians and natural philosophers. The period was crucial for his development in mathematics and for his conviction that a rational symbolism could transform inquiry.
Development of Calculus Notation
**1676** — During the mid-1670s Leibniz developed the differential and integral notation that became standard in mathematics. Although the priority dispute with Newton later complicated the story, Leibniz’s notation proved extraordinarily influential.
Discourse on Metaphysics
**1686** — Leibniz wrote the "Discourse on Metaphysics," one of the clearest early formulations of his mature philosophy. It presents his view of substance, divine choice, and the intelligibility of creation in compressed but decisive form.
The New System Circulates
**1697** — Leibniz’s ideas about pre-established harmony and monads began to circulate more widely in Europe. This period marked the emergence of the metaphysical architecture that would later define his reputation.
Locke and Leibniz in Philosophical Contrast
**1704** — The publication and circulation of Locke’s empiricism sharpened the contrast between Leibnizian rationalism and British experimental philosophy. Leibniz’s response took shape in the "New Essays on Human Understanding," though it would appear only posthumously.
Theodicy Published
**1710** — Leibniz published "Essais de Théodicée," his most sustained defense of divine justice and the best possible world. The work brought his optimism into open debate and established the phrase that would later dominate his public image.
Monadology Composed
**1714** — Leibniz composed the "Monadology," a compact summary of his mature metaphysics. It condenses his theory of monads, perception, and pre-established harmony into one of the most famous short texts in philosophy.
Death of Leibniz
**1716** — Leibniz died in Hanover in 1716, neglected by the court he had served for decades. His death marked the end of one of the most wide-ranging philosophical lives in European history, but not the end of the debates he helped define.
Voltaire Satirizes Leibnizian Optimism
**1759** — Voltaire’s "Candide" transformed Leibnizian optimism into a cultural target. The novel ensured that generations of readers would encounter Leibniz first as a symbol of excessive philosophical confidence, even when the doctrine itself was more nuanced.
