The “philosophy course” comprises four overarching fields of study, namely, philosophy, ethics, religious studies, and esthetics. In the narrow sense, the field of philosophy encompasses diverse topics based on an understanding of the history of Western philosophy from Ancient Greece to the present day. These topics include logic, which is concerned with the principles of reasoning essential to academic thought; ontology, which considers the world and the position of human existence within it; and epistemology, which discusses the origins of and grounds for our knowledge of the world.
