This document discusses key concepts of existentialism including ontology, epistemology, ethics, and being. It outlines existentialist views on teaching and learning, curriculum, and provides a critique. The document is divided into two parts. Part A covers existentialist proponents such as Kierkegaard, Nietzsche, Sartre, and Jaspers and their views on reality, knowledge, morality, and human development. Part B discusses implications for education including how the learner should be able to freely identify what is good for themselves, the role of the student in curriculum choices, and existentialist criticisms of school as dehumanizing.
