The matter is I can't imagine what these criteria may be in case of Philosophy, because philosophical systems differ very much, they often contradict each other, so if one view or another doesn't fit any given philosophical system, that never means it has no philosophical value. Who has worked out "universal criteria" for all Philosophy which can be applied to any work of any philosopher? For example, Plato's Parmenides and Heidegger's Zein und Zeit: how much are they alike?
