"The relation between logic and metaphysics is frequently obscure in translations and interpretations of Aristotle. Apostle's method of translation-one English word for one Greek word-makes his English text a faithful replica of the Greek original. The reader of his translations of the Posterior Analytics and of the Metaphysics will find a clear presentation of the difference between the metaphysical foundation of the organization of the sciences relative to the kinds of substances in Book Lambda of the Metaphysics and the logical analysis of definition and demonstration relative to terms and propositions in Book Beta of the Posterior Analytics."

"If what is wanted is an accurate, consistent and intelligible translation (rather than a paraphrase) of Aristotle's logic of scientific reasoning, then by far Apostle's translation is to be preferred for serious study in the English language; such a study is greatly facilitated by extensive philosophical and textual notes, often illustrated by mathematical examples."
