In The Principles of Mathematics, Bertrand Russell set forth his logicist thesis that the concepts of non-applied mathematics are those of pure logic. In this revisionist interpretation. Gregory Landini explores an important central thread that unifies Russell’s thoughts on logic in the two works. The heart of Landini’s book is a careful presentation and exploration of Russell’s largely unpublished “substitutional” theory of propositions.
