  Aristotle uses mathematics and mathematical sciences in three important ways in his treatises. Contemporary mathematics serves as a model for his philosophy of science and provides some important techniques, e.g., as used in his logic. Throughout the corpus, he constructs mathematical arguments for various theses, especially in the physical writings, but also in the biology and ethics. Finally, Aristotle's philosophy of mathematics provides an important alternative to platonism. In this regard, there has been a revival of interest in recent years because of its affinity to physicalism and fictionalisms based on physicalism. However, his philosophy of mathematics may better be understood as a philosophy of exact or mathematical sciences.
