[Footnote 2: Justus, no doubt, had done the converse, representing himself as a thorough Romanizer and Josephus as an ardent rebel.] At the end of the _Antiquities_ Josephus declares his intention to write three books concerning the Jewish doctrines "about God and His essence, and concerning the laws, why some things are permitted, and others are prohibited." In the preface to the same work, as well as in various passages in its course, he refers to his intention to write on the philosophical meaning of the Mosaic legislation. The books entitled _Against Apion_ correspond neither in number nor in content to this plan, and we must therefore assume that he never carried it out. He may have intended to abstract the commentary of Philo upon the Law, which he had doubtless come to know. Certainly he shows no traces of deeper allegorical lore in the extant works, and his mind was hardly given to such speculations. But a humanitarian and universalistic explanation of the Mosaic code, such as his predecessor had composed, notably in his Life of Moses, would have been quite in his way, and would have rounded off his presentation of the past and present history of the Jews. The need of replying to his personal enemies and the detractors of his nation deterred him perhaps from achieving this part of his scheme. Or, if it was written, the Christian scribes, who preserved his other works, may have suppressed it because it did not harmonize with their ideas. Photius ascribes to Josephus a work on _The Universe_, or _The Cause of the Universe_ ([Greek: peri taes tou pantos aitias]), which is extant, but which is demonstrably of Christian origin, and was probably written by Hippolytus, an ecclesiastical writer of the third century and the author of _Philosophumena_. Another work attributed to Josephus in the Dark and Middle Ages, and often attached to manuscripts of the _Antiquities_, is the sermon on _The Sovereignty of Reason_, which is commonly known as the Fourth Book of the Maccabees. The book is a remarkable example of the use of Greek philosophical ideas to confirm the Jewish religion. That the Mosaic law is the rule of written reason is the main theme, and it is illustrated by the story of the martyrs during the persecution of Antiochus Epiphanes, whence the book takes its title. In particular, the author points to the ethical significance underlying the dietary laws, of which he says in a remarkable passage: When we long for fishes and fowls and fourfooted animals and every kind of food that is forbidden to us by the Law, it is through the mastery of pious reason that we abstain from them. For the affections and appetites are restrained and turned into another direction by the sobriety of the mind, and all the movements of the body are kept in check by pious reason. Again, of the Law as a whole he says:
