Hi Dynamix , your question about dualism is a bit complicated , made even more so by the fact that , 1. I am not a physicist and , 2. since I am not God I don’t have the capacity to plumb the depths and heights of these things and know them as they in fact are. So , the best I can do is to try to get a sense of these things and reason them out. And my reasoning may prove to be wrong , in which case I am always glad to amend my previously held opinions and embrace truth wherever I may find it. As to your surprise that you may have found a strange Mormon , at odds with the beliefs of his fellows , in the first instance your perception of me may not be quite correct , owing to a failure on my part to communicate clearly. Secondly , though Mormons tend to be united in belief on the major points of the Gospel of Jesus Christ , there is quite a wide variety of beliefs and views among Mormons about any number of subjects , both temporal and spiritual . Having made this introduction , I’ll try to answer your questions above.
When I wrote that we need to keep in mind that matter exists in more than one way , I may have miscommunicated my intent. My intent was that matter is manifested in more than one way. There is the form of matter that we can see (physical / natural) in our current human condition and there is matter that we cannot see (spiritual). Joseph Smith said that spirit matter is more pure and refined than physical matter and that we cannot see spirit matter with our natural eyes. We can see natural matter (the physical body of flesh , bones , blood and other natural things) but there is matter which we cannot see unless we comprehend it with our spiritual faculties. It seems to me though , that spirit matter (which Joseph Smith described as “Intelligence”) is the animating substance of physical matter. In the Bible we read from James “For as the body without the spirit is dead…”(James 2:26). It would appear that it is the spirit which animates the body , gives life to the physical. It was not until God breathed Adam’s spirit into his formed physical body that Adam became a living soul. And without the spirit (spirit matter) the body is dead and inanimate. Yet , though the body is inanimate at death it remains in our view as physical matter , separate from the departed spirit matter (Intelligence) which gave the body life.
In all honesty , I have not really thought much about these things until this thread and am just now reasoning my way through, the things which I have just written above having given me more cause to consider their ramifications. Are physical and spiritual matter substantially different or are they the same kind of matter manifested differently to our senses , as water may be manifested as either a solid or a gas? Or is it the case that , since spirit matter has the quality of Intelligence and it animates the matter of the physical body (and presumably the other physical manifestations of matter as in trees , plants , animals , etc) is spirit matter substantially a different kind of matter than physical matter? I can’t give you a definitive answer. I simply , at this point , don’t know. Sorry.
The other question about the Arctic has already been answered by someone else. The quote does exist as you posted it here , though it has been errantly attributed to Joseph Smith by your source. The quote is actually found in the Journal of Discourses and was made by Orson Pratt during a sermon he gave (Discourse by Elder Orson Pratt , July 25 , 1875 , 18:57). I think that a careful reading of what Elder Pratt actually said will allay any concerns you might have that Elder Pratt was saying that the 10 Tribes are living somewhere in deep snows and ice of the North Pole. Please take notice that Elder Pratt referred to the “north” , a rather broad reference and to the Arctic regions. I looked up the places which constitute the Arctic region and found :
The Arctic includes the Arctic Ocean (which overlies the North Pole) and parts of Canada, Greenland (a territory of Denmark), Russia, the United States (Alaska), Iceland, Norway, Sweden and Finland.
It would seem , then , that Elder Pratt may have believed that the 10 Tribes spoken of had been scattered among these nations and would come to Zion from this “north” and these “Arctic regions” from among the countries noted above.
