These materials represent unpublished versions of articles, book chapters, and conference papers, with the vast majority being articles intended for publication in scholarly journals. The manuscripts are arranged alphabetically by author and in the case of coauthors, the manuscript is filed by the primary listed author. While this series contains works written by Sellars's peers, the authors here are largely his former students. These student manuscripts reveal their development as professionals in the philosophical community. Most of the manuscripts do not contain annotations, and those that do have minimal markings consisting of underlined sections and minimal commentary in the margins. Approximately half of the manuscripts contain cover letters, which generally introduce the manuscript and solicit comments from Sellars. The topics covered in these manuscripts are strictly philosophical and center on Sellars's expertise in philosophy of mind, epistemology, meaning, pragmatism, and history of philosophy. Some notable exceptions to the minimal annotations are the manuscripts originating from Rigoberto Juarez-Paz, which were heavily annotated. Also noteworthy are the manuscripts of Robert Turnball's "Aseity and Dependence in Leibniz's Metaphysics" and Gregory Vlastos's "The Senonian Argument Against Plurality," which contain detailed critiques from Sellars. While a generalization, one could also state that the manuscripts Sellars most heavily analyzed were those that referred to his own works.
