In what sense there is no science of curruptible things: an analysis of Posterior Analytics I 8

Aristotle claims that the object of scientific knowledge cannot be otherwise, and at Posterior Analytics I-8 Aristotle adds that there is no scientific knowledge of corruptible objects. These claims have been traditionally understood in terms of a strict requirement of eternal existence: objects of genuine scientific knowledge must be eternal in the sense that they must exist eternally. In this paper, I offer an alternative view and discuss Aristotle’s argument in Posterior Analytics I-8. Keywords: Scientific explanation. Essentialism. Causality. Demonstration. Knowledge. Ontology.
