Editorial note — B. — Aristotle’s Doctrine.

The author nowhere states the principle upon which he selected the six books for a preliminary Abstract; but the actual selection, joined to various indications in the Abstract and marginal notes in his copies of the Metaphysica, leaves no doubt that he accepted the view of Brandis, more especially as set forth by Bonitz. On the whole question of the Canon of the Metaphysica, Bonitz’s Introduction to his Commentary may with advantage be consulted.]
