In this article, the author demonstrated how recent histories relied primarily on previous accounts and one textbook to characterize George Pierce Baker's work. This narrow assessment of "The Principles of Argumentation" limits one's understanding of his contribution to argumentation theory and pedagogy. Similarly, one has seen the need for care when quoting and using different editions of his text. In addition, the author has argued that an analysis of any textbook is not enough to understand its potential use in the classroom. (Contains 20 notes.)
