 It would be difficult to exaggerate the influence of Reinhold’s inquiries into systematicity and first principles upon an entire generation of philosophers. Though some recent research on Reinhold and the “Jena circle” of the late 1780s has stressed the degree to which Reinhold himself soon came to have doubts about the project of “philosophy from a single principle” (see the work of Dieter Henrich and his students, such as Marcello Stamm), this project was nevertheless enthusiastically embraced by Fichte and the young Schelling, and inspired others, notably Hegel, to re-examine (and to question) the alleged connection between systematic form and self-evident first principles. Reinhold’s subsequent reservations about his own Elementary Philosophy notwithstanding, the Elementary Philosophy remains one of the clearest examples of a thoroughgoing “foundationalist” project in the history of European philosophy.
