gether by him, or, perhaps, from the composition of the work at different times—are questions, like the similar question about the “Iliad” and the “Odyssey,” which are worth asking, but which cannot have a distinct answer. In the age of Plato there was no regular mode of publication, and an author would have the less scruple in altering or adding to a work which was known only to a few of his friends. There is no absurdity in supposing that he may have laid his labors aside for a time, or turned from one work to another; and such interruptions would be more likely to occur in the case of a long than of a short writing. In all attempts to determine the chronological order of the Platonic writings on internal evidence, this uncertainty about any single dialogue being composed at one time is a disturbing element, which must be admitted to affect longer works, such as the “Republic” and the “Laws,” more than shorter ones. But, on the other hand, the seeming discrepancies of the “Republic” may only arise out of the discordant elements which the philosopher has attempted to unite in a single whole, perhaps without being himself able to recognize the inconsistency which is obvious to us. For there is a judgment of after-ages which few great writers have ever been able to anticipate for themselves. They do not perceive the want of connection in their own writings, or the gaps in their systems which are visible enough to those who come after them. In the beginnings of literature and philosophy, amid the first efforts of thought and language, more inconsistencies occur than now, when the paths of speculation are well worn and the meaning of words precisely defined. For consistency, too, is the growth of time; and some of the greatest creations of the human mind have been wanting in unity. Tried by this test, several of the Platonic dialogues, according to our modern ideas, appear to be defective, but the deficiency is no proof that they were composed at different times or by different hands. And the supposition that the “Republic” was written uninterruptedly and by a continuous effort is in some degree confirmed by the numerous references from one part of the work to another.
The second title, “Concerning Justice,” is not the one by which the “Republic” is quoted, either by Aristotle or generally in antiquity, and, like the other second titles of the Pla-
