The next great dividing line separating the Conservatives from the rest concerns an understanding of the nature of reality. Conservatives believe that while there is an objective reality which is extrinsic to their perception, not all of this reality is perceptible. In other words, there is a realm of existence which we cannot access directly with our senses. It is in this realm where stuff like universals, souls, gods and sky pixies of various types inhabit. With the exception of modern man, nearly all of the peoples that have ever lived believed that reality comprised an earthly component and a heavenly one. Be that Nirvana, Valhalla, Penglai Shan, Heaven, Aukumea, etc.
I suppose the minimum belief that a man can have and still be called a Conservative is agnosticism. Strict Empiricism, that is the denial of any plane of reality outside that which accessible by the senses separates a man from the conservative fold.
The importance of this "plane of non- perceptible reality" is that from it arise many of the transcendental imperatives by which a man must live his life. Ought can't be derived from is from the earthly plane but can be derived from from the transcedental one.
