Metaphysicians go on busily doing metaphysical thinking all over the world, and apparently with a modicum of self-assurance that they are not talking nonsense or pursuing an illusory will-of-the-wisp. Yet other philosophers of empirical, analytical, phenomenological, or other turns of mind seem to have more and more difficulty in understanding just how metaphysicians give meaning and positive content to the vast abstract concepts by which they seek to describe and explain the entire spectrum of reality extending far beyond present or (...) perhaps even possible human experience. Since there is no way of gaining direct insight into dimensions of reality beyond human experience, and since in order to be applied to the whole range of reality these concepts must abstract from purely human experience, it is hard for them to see—and it is a serious problem in itself—how these all-embracing terms can be anything more than empty, formal, verbal symbols or conceptual constructions, with no positive existential content describing reality itself across its whole spectrum. Even the metaphysician himself, though when left alone he may have a sure sense of how to do metaphysical thinking fruitfully, when questioned to explain and justify what he is doing, and is convinced is worth doing, can feel embarrassed and struck dumb as to how to articulate and justify the principles behind the procedures he is following.
