The present gives a brief exposition of the logical work of Frege, Peano, and Bertrand Russell. For by "Formal Logic" Mr. Shearman means here what has been variously designated by the names "symbolic logic," "mathematical logic," "algebra of logic," "symbol logic" (Mrs. Ladd-Franklin), "logistic" (Couturat). This kind of logic has not yet found its fitting name; but it is " making history." The purpose of "The Scope of Formal Logic" is to convince the reader of the importance of the work in this field, and, without presupposing any familiarity with the writings of Frege, Peano, Russell, to lead the uninitiated to these fountain-heads of modern logical thought. In the first chapter a number of important terms, such as "propositional function," "variable," etc., are elucidated. In the second chapter Frege's, Peano's, and Russell's symbols, or at least some of the more frequent among them, are explained by translating several propositions, some simple, some more complex, from their symbolic statements into English.
