 The other is the topic of this essay: the problem of the specific engagement between science and early Chinese philosophy, and whether Chinese philosophy was in some way inimical to scientific inquiry. To answer the latter questions it is necessary to consider both the intellectual and social contexts of Chinese philosophy and Chinese science. Which sciences are relevant to Chinese philosophy? Using Sivin's categorization, the quantitative sciences are largely separate from the engagement between science and early Chinese philosophy. The greatest degree of engagement between philosophy and science comes from the qualitative sciences of astronomy (or astrology) and medicine.
