Introduction

A summary of Leibniz’s metaphysics in 90 short paragraphs, written in French in Vienna in 1714 without a title. It first appeared in a German translation in 1720 (“Monadologie” comes from this edition) and in Latin in 1721; the French original was printed only in 1840. In the same year Leibniz wrote a related text, the “Principles of Nature and Grace”, for Prince Eugene of Savoy. The Monadology describes simple substances that have perception and appetite but no parts and no “windows”. A famous paragraph imagines walking into a thinking machine enlarged to the size of a mill: one would find only parts pushing one another, never a perception.
