They revealed that Leibniz developed in succession several versions of a \u201clogical calculus\u201d (<jats:italic>calculus ratiocinator<\/jats:italic>or<jats:italic>calculus universalis<\/jats:italic>). In consequence of Couturat's investigations it has become well known that Leibniz's development of these logical calculi adumbrated the notion of a logistic system; and for these foreshadowings of the logistic treatment of formal logic Leibniz is rightly regarded as the father of symbolic logic.<\/jats:p><jats:p>It is clear from what has been said that it is scarcely possible to overestimate the debt which the contemporary student of Leibniz's logic owes to Couturat. This gratitude must, however, be accompanied by the realization that Couturat's own theory of logic is gravely defective. Couturat was persuaded that the extensional point of view in logic is the only one which is correct, an opinion now quite antiquated, and shared by no one. This prejudice of Couturat's marred his exposition of Leibniz's logic. It led him to battle with windmills: he viewed the logic of Leibniz as rife with shortcomings stemming from an intensional approach.<\/jats:p><jats:p>The task of this paper is a re-examination of Leibniz's logic. It will consider without prejudgment how Leibniz conceived of the major formal systems he developed as<jats:italic>logical<\/jats:italic>calculi \u2013 that is, these systems will be studied with a view to the interpretation or interpretations which Leibniz himself intends for them. The aim is to undo some of the damage which Couturat's preconception has done to the just understanding of Leibniz's logic and to the proper evaluation of his contribution.<\/jats:p>","DOI":"10.2307\/2267644","type":"journal-article","created":{"date-parts":[[2006,5,6]],"date-time":"2006-05-06T19:30:20Z","timestamp":1146943820000},"page":"1-13","source":"Crossref","is-referenced-by-count":15,"title":["Leibniz's interpretation of his logical calculi"],"prefix":"10.1017","volume":"19","author":[{"given":"Nicholas","family":"Rescher","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2014,3,12]]},"reference":[{"key":"S0022481200088344_ref018","first-page":"379","volume-title":"Opuscules et fragments","volume":"2\u20133"},{"key":"S0022481200088344_ref017","first-page":"218","volume-title":"Phil.
