A shorter and less technical treatment of its subject than the author's acclaimed Buddhism As Philosophy (second edition, Hackett, 2021), Mark Siderits's The Buddha's Teachings As Philosophy explores three different systems of thought that arose from core claims of the Buddha. By detailing and critically examining key arguments made by the Buddha and developed by later Buddhist philosophers, Siderits investigates the Buddha's teachings as philosophy: a set of claims--in this case, claims about the nature of the world and our place in it--supported by rational argumentation and, here, developed with a variety of systematic results. The Buddha's Teachings As Philosophy will be especially useful to students of philosophy, religious studies, and comparative religion--to anyone, in fact, encountering Buddhist philosophy for the first time.
