ABSTRACT
In 1896 Charles S. Peirce wrote two review articles for the Monist on Ernst Schroder's Vorlesungen uber die Algebra der Logik. The first review, devoted to the first volume of the Vorlesungen and titled "The Regenerated Logic", appeared in October 1896. The second, devoted to the third volume of the Vorlesungen and titled "The Logic of Relatives", appeared in January 1897. Peirce proposes a rectification of that old doctrine which takes into account the discoveries in the logic of relatives and in the analysis of assertion and inference that he has made in the meanwhile. An analysis of the conception of assertion, and thus an introduction to the principal concepts of speculative grammar, is thus requisite in any exposition of the method of logical graphs. In the Entitative Graphs that Peirce presents in the "Logic of Relatives", the oval is an integral part of the bond.
