This article proceeds along five sections. The first section, Foreword, explains the why this article is titled as “Immortality and Reality,” which is based on Chao's philosophical theories on the one hand and explicates the Scholastic view of the history of philosophy on the other hand. The second section is divided into two parts to illustrate Chao's ideas about how to study the history of western philosophies; the first part analyzes the internal components of the history of philosophy, while the second part analyzes how the history of philosophy as a whole relates to other academic disciplines. The third section is his evaluations about all the different schools on the history of philosophy, whereby he evaluates and analyzes more than a dozen philosophical schools and categorizes them into rationalism, empiricism and Aristotelianism. The fourth section discusses the Scholastic view of the history of philosophy, highlighting moderate realism, which revolves around Aristotle and Aquinas, and distinguishing between philosophy and religion. The fifth section is to evaluate the Scholastic view of the history of philosophy, including its reality, immortality, substantiality, integrativeness and transcendence.
