This presentation discusses the main branches of philosophy. It identifies metaphysics, logic, epistemology, and axiology as the key branches. Metaphysics concerns fundamental questions about the nature of reality. Epistemology is concerned with the nature and scope of knowledge, including the different sources and types of knowledge. Logic deals with questions about reference, predication, identity, truth, and quantification. Axiology examines the nature and types of values, especially in ethics and religion. The presentation suggests that questions in these philosophical branches relate to curriculum design and determining what knowledge and values are most important to teach students.
