The concept of "philosophy" originated in the West, and its connotation has undergone multiple changes throughout the evolution of Western history. This complexity makes it difficult to provide a precise definition, even as it has become a specific discipline within universities today. As an introductory course in philosophy, this class aims to guide beginners without a philosophical background through the historical context of the evolution of the concept of "philosophy." Based on the results of today's specialized divisions, the course will systematically introduce the main subjects encompassed within the discipline of philosophy, along with its classics, mainstream ideas, and fundamental important questions. This will provide beginners with a comprehensive learning map, facilitating deeper research based on their interests in the future. The first half of the semester will focus on theoretical philosophy, introducing metaphysics, epistemology, philosophy of mind, and philosophy of language. The second half will emphasize practical philosophy, primarily covering ethics and political philosophy.
