Chapter Summary. Part i made a case for seeing the Posterior Analytics ii in a new light. In that new light, it does not provide poor answers to questions people bring to it about the path by which inquiry takes us from perceptual experience to first principles of demonstration. Rather it provides very good answers to questions about what questions ought to shape any inquiry aimed at knowledge and about how the answers to those questions are related to one another – it provides, that is, an erotetic framework for inquiry. Many of the norms that guide scientific inquiries, however, are domain-specific, and are not to be found in APo., though they are best seen as different ways of specifying the framework provided by the Analytics.
