Of course, like all over-simple classifications of this type, the dichotomy becomes, if pressed, artificial, scholastic, and ultimately absurd. But if it is not an aid to serious criticism, neither should it be rejected as being merely superficial or frivolous; like all distinctions which embody any degree of truth, it offers a point of view from which to look and compare, a starting-point for genuine investigation.
