  Another reason one sometimes encounters for denying that the Buddha is a philosopher is that he rejects the characteristically philosophical activity of theorizing about matters that lack evident practical application. On this interpretation as well, those later Buddhist thinkers who did go in for the construction of theories about the ultimate nature of everything simply failed to heed or properly appreciate the Buddha’s advice that we avoid theorizing for its own sake and confine our attention to those matters that are directly relevant to liberation from suffering. On this view the teaching of non-self is not a bit of metaphysics, just some practical advice to the effect that we should avoid identifying with things that are transitory and so bound to yield dissatisfaction. What both interpretations share is the assumption that it is possible to arrive at what the Buddha himself thought without relying on the understanding of his teachings developed in the subsequent Buddhist philosophical tradition.
