Abstract
This welcome edition, the first volume of The Yale Leibniz, contains synoptically the original Latin text and an English translation of the very important philosophical papers written by Leibniz during his Paris period: on the one hand the series of the Elementa philosophiae arcanae de summa rerum from December 1675 to April 1676, and on the other hand a selection of the most important metaphysical texts and notes from March to December 1676. The printed text follows the Academy Edition, Series VI, vol. 3, but with the intention to make a readable edition for students and scholars does not include Leibniz's revision steps.
