Husserl on Schroeder's View of Logic

We aim at clarifying to what extent the work of the German mathematician Ernst Schröder (1841-1902) on the algebra of logic is taken into consideration and re- hashed in the work of the early Husserl, focusing on Husserl’s 1891 Review of the first vol- ume of Schröder’s monumental Vorlesungen über die Algebra der Logik (Exakte Logik) and on Husserl’s text Der Folgerungskalkül und die Inhaltslogik written in the same year. We will try to show how and why Husserl, while praising Schröder’s calculus, strongly criticizes Schröder’s attempt at a philosophical clarification and justification of it.
