Idealism is the oldest school of philosophy that focuses on ideas and ideals rather than material things. It believes that God or the mind is the source of all creation and knowledge, and that spiritual aspects are more important than the physical world. Some of the main proponents of idealism include Plato, Kant, Hegel, Gandhi, and Tagore. The principles of education under idealism stress spiritual development and self-realization over worldly concerns. The aim of education is to help students unfold their divine nature and cultivate eternal values like truth, goodness, and beauty.
