Existentialism, emerging primarily in Europe before World War II, emphasizes that existence precedes essence, highlighting individual freedom and subjectivity over objective truths. Key philosophers like Kierkegaard, Nietzsche, Heidegger, and Sartre shaped its principles, advocating for an education system that fosters personal development, self-realization, and moral understanding. Critics argue that existentialism's application in educational settings may be limited due to its emphasis on individual freedom contrasting with conventional schooling structures.
