German idealism
Dieter Henrich's 1973 lecture course on German Idealism introduced to American audience the contemporary currents in German philosophy. His lectures were since then published as "Between Kant and Hegel" that showed the continuity between German idealism and contemporary philosophical attitudes. Henrich introduced the idea that I-thoughts (what he also called "the epistemic self-relation" ["Das wissende Selbstverhältnis"]) imply a belief in the existence of a world of objects.
