The new research series "Theoria" assembles systematic research work on theoretical philosophy. "Theoria" covers – but is not limited to – the core areas of theoretical philosophy, such as, inter alia, philosophy of language, philosophy of the mind, epistemology, or metaphysics. There is special focus on works that not only are systematically adept but also are historically informed and make the history of philosophy productive for systematic questions. The series is open for philosophical perspectives of diverse traditions of thinking, and accepts aside from research monographs also compellingly conceived anthologies and annotated text volumes. The professional expertise of the editorial team assures a high quality of publication. The languages of publication are German and English.
