Perennialism focuses on teaching principles rather than facts, and believes education should develop students' rational and moral powers. It recommends teaching liberal topics like humanities, arts, theology and history by having students read the great books of influential thinkers from the past. Perennialists believe this approach cultivates a sound personality and prepares students for lifelong learning and understanding universal truths. They stress teaching subjects like philosophy, languages, sciences and more that provide a well-rounded liberal arts education.
