The Aristotelian paradigm of “saving the phenomena” in Geminos’s <i>Introduction to the Phenomena</i>

Unlike Euclidian and Ptolemaic approaches, Geminos doesn’t use many geometric proofs in Introduction to the Phenomena. To explore the approaches of Geminos, this article analyses the cognition of “phenomena” and the methods being used to establish the legitimacy of theories by Geminos and Aristotle. Aristotle and Geminos both take “phenomena” as sensory experience and rational knowledge. In their treatises, “phenomena” hold a central position, serving as a crucial criteria. Whether one kind of perception or theory is correct lies in its harmony with phenomena. Therefore, Geminos used the same paradigm of “saving the phenomena” as Aristotle.
