ON GENERATION AND CORRUPTION: The passions to which bodies in the sublunar realm are subjected, generation and corruption, are explained and distinguished from similar phenomena. The material components of all created things are the four basic elements. How they combine or transform into one another. Material, formal, and final cause of generation and corruption.

ON THE COSMOS: Theological cosmology, based on Aristotelian views but with clear influences from other schools (Neopythagoreans, Stoics). A spurious work, likely from the period of eclecticism. Aristotle, son of the physician Nicomachus, was born in Stagira in 384 BC. There is very little information about the early years of his life. At the age of seventeen, he went to Athens to study at the Platonic Academy. He stayed there for twenty years, from 367 to 348 BC, until Plato's death.

Then Aristotle left for Assos in Troas and after a three-year stay there, went to Lesbos and then to Macedonia, where he took on the education of the royal youth, Alexander. When his student ascended the throne, Aristotle settled in Athens and founded his school, the Lyceum. After Alexander's death (323 BC), the philosopher's stay in Athens became difficult. He was forced to flee to Chalcis, his mother's homeland, where he died in 322.

A universal spirit, Aristotle created a vast and valuable philosophical and scientific work. Epistemology, logic, theology, physics, biology, psychology, ethics, political philosophy, aesthetics are the main areas of knowledge he researched and studied. The Alexandrian Hermippus estimated Aristotle's works at 400. Lists containing 143 titles of his works have survived to us. Diogenes Laertius estimated the number of verses in Aristotelian writings at 440,000. The impact of his work on the formation of global thought was, for centuries, and remains, strong.
