The Posterior Analytics (Greek: ????????? ??????; Latin: Analytica Posteriora) is a text from Aristotle’s Organon that deals with demonstration, definition, and scientific knowledge. The demonstration is distinguished as a syllogism productive of scientific knowledge, while the definition marked as the statement of a thing’s nature, ... a statement of the meaning of the name, or of an equivalent nominal formula.

Aristotle's “Posterior Analytics”, Book II, Chapter 19, contains one of the most significant texts in the history of philosophy and, in particular, the field of epistemology. Paolo C. Biondi's book offers a new English translation, along with a commentary and critical analysis, of this important text. The originality of the translation is grounded in the exegesis found in the commentary, which also provides an overview of the interpretations of many Aristotelian philosophers from the Greek commentators through to contemporary scholars. The critical analysis is an in-depth essay on Aristotle's thoughts on logic and psychology. Even though the essay's main argument — that human intuition lies at the base of the mind's grasp of the principles of science — reaffirms the traditional position, the conclusion is arrived at by an ingenious step-by-step study of each of the various human faculties of cognition, a study that is much like the process of putting together the pieces of a puzzle.

This study explores the theoretical relationship between Aristotle’s theory of syllogism and his conception of demonstrative knowledge. More specifically, I consider why Aristotle’s theory of demonstration presupposes his theory of syllogism. In reconsidering the relationship between Aristotle’s two Analytics, I modify this widely discussed question. The problem of the relationship between Aristotle’s logic and his theory of proof is commonly approached from the standpoint of whether the theory of demonstration presupposes the theory of syllogism. By contrast, I assume the theoretical relationship between these two theories from the start. This assumption is based on much explicit textual evidence indicating that Aristotle considers the theory of demonstration a branch of the theory of syllogism. I see no textual reasons for doubting the theoretical relationship between Aristotle’s two Analytics so I attempt to uncover here the common theoretical assumptions that relate the syllogistic form of reasoning to the cognitive state (i. e. , knowledge), which is attained through syllogistic inferences. This modification of the traditional approach reflects the wider objective of this essay. Unlike the traditional interpretation, which views the Posterior Analytics in light of scientific practice, this study aims to lay the foundation for a comprehensive interpretation of the Posterior Analytics, considering this work from a metaphysical perspective. One of my major assertions is that Aristotle’s conception of substance is essential for a grasp of his theory of demonstration in general, and of the role of syllogistic logic in particular.
