[3] His philosophical standpoint may be characterized as a reaction from the pantheistic tendency of Hegel's idealistic rationalism towards a more pronouncedly theistic position.

[3] Ulrici's later works, while expressing the same views, are largely occupied in proving the existence of God and the soul on the basis of scientific conceptions, and in opposition to the materialistic current of thought then popular in Germany.

His first works were in the sphere of literary criticism; of his treatise On Shakespeare's Dramatic Art (1839; editions, 1847, 1868, 1874), the 3rd ed.

In 1841 he published Ueber Princip und Methode der Hegelschen Philosophie, a severe criticism of the Hegelian system.

From 1847 onward Ulrici edited, jointly with I. H. Fichte, the Zeitschrift für Philosophie und philosophische Kritik.
