According to Immanuel Kant, all rational knowledge is either material or formal: the former considers some object, the latter is concerned only with the form of the understanding and of the reason itself, and with the universal laws of thought in general without distinction of its objects. Formal philosophy is called Logic. Material philosophy, however, has to do with determinate objects and the laws to which they are subject, is again twofold; for these laws are either laws of nature or of freedom.

One of Kant's most well-known and classic philosophical writings, this is well worth reading for any student.

Immanuel Kant was one of the most important German philosophers during the Enlightenment, teaching and writing about philosophy and bridging those from the rationalist and empiricist schools of thought. His most famous works discuss metaphysical concepts like morality and reason.
