  Rubin was an ardent admirer of the system and personality of Spinoza; and wrote much to prove the close relation between Spinozism and Judaism.Among his earliest literary productions are a compendium of Spinoza's writings, entitled "Moreh Nebukim he-Ḳadash" (Vienna, 1856-1857), and "Teshubah Niẓẓaḥat" (Lemberg, 1859), a refutation of S. D. Luzzatto's attacks on Spinoza.Rubin's essay in German, "Spinoza und Maimonides, ein Psychologisch-Philosophisches Antitheton", won for the author the title of doctor of philosophy from the University of Göttingen.
