Metaphilosophy
Metaphilosophy (sometimes called philosophy of philosophy) is "the investigation of the nature of philosophy". Its subject matter includes the aims of philosophy, the boundaries of philosophy, and its methods. It is considered by some to be a subject apart from philosophy, while others see it as automatically a part of philosophy, and still others see it as a combination of these subjects. The interest in metaphilosophy led to the establishment of the journal Metaphilosophy in January 1970.
Relationship to philosophy
Some philosophers consider metaphilosophy to be a subject apart from philosophy, above or beyond it, while others object to that idea.Timothy Williamson argues that the philosophy of philosophy is "automatically part of philosophy", as is the philosophy of anything else. Nicholas Bunnin and Jiyuan Yu write that the separation of first- from second-order study has lost popularity as philosophers find it hard to observe the distinction. As evidenced by these contrasting opinions, debate persists as to whether the evaluation of the nature of philosophy is 'second order philosophy' or simply 'plain philosophy'.
