This is the first translation into English of a work of late German enlightenment by Karl Leonhard Reinhold (1757-1823). Reinhold was an acute thinker, who is best known for his interpretations of Kant and whose writings on theoretical philosophy were decisive for the development of philosophy after Kant. Roehr's extensive historical-analytical work provides the context necessary for fully appreciating Reinhold's work. She analyzes the moral, religious, political, and philosophical elements of the period, as well as the history of their development. Philosophers, political theorists, historians, theologians, and eighteenth-century scholars in general will gain much insight from this valuable study and the accompanying translation.
