The division of philosophy into a practical philosophy and a theoretical discipline has its origin in Aristotle's moral philosophy and natural philosophy categories. In Sweden and Finland courses in theoretical and practical philosophy are taught separately, and are separate degrees. Other countries may use a similar scheme—some Scottish universities, for example, divide philosophy into logic, metaphysics, and ethics—but in most universities around the world philosophy is taught as a single subject. There is also a unified philosophy subject in some Swedish universities, such as Södertörns Högskola.
