Four Spacetime Dimensions as “Type” Dichotomies
Been trying to develop this analogy for awhile, based on the four type dichotomies (Sensing/iNtuition [perception of tangible reality vs ideas], Thinking/Feeling [impersonal vs soul-affecting judgments], introversion/extraversion [inner vs outer focus], rationality/irrationality of our preferred “outer” directed function [used to help determine which is our “dominant” perspective]) as “divisions of reality”.
So I realized that the four “dimensions” I often compare to as the easiest illustration of how we “divide” reality, would be the best to extend to a full analogy.
So we start with a person facing one of the compass directions that we rotate in, N, E, S, W. He can also look up or down while looking in one of those directions. Two of the compass directions will correspond to Latitude (E/W), and the other one will be Longitude (N/S).
The opposite direction is totally behind him (basically, unconscious), but the perpendicular directions are in the corner of his eyes, and the nonvertical ones are basically the directions of his two arms. So we can imagine one of these directions is “secondary”. Primary and secondary are determined by the fourth spacetime “dimension”, Past and Future. He will look at his primary direction first, and then the secondary direction second.
So we have a person with one preferred horizontal direction, and one preferred vertical direction. He also has a secondary horizontal direction that he looks in afterward, and we have to presume that for the sake of “balance” for some reason, he must look the opposite vertical direction when looking in that direction (this is where the practicality breaks down. I tried to imagine a scenario where something would force the opposite “orientation” for the different directions).
When looking one direction, the other three are “undifferentiated” in that you are equally “blind” to them (to some extent), so they all are the same in being invisible (left and right, however, are partly differentiated in that you can see them a bit in the corner of your eye).
Basically, we should assume that since he spends most of his time looking in one direction, and he tends to look either up or down in that direction (perhaps observing something in that direction that directs his vision either up or down), when he has to look in any of the other directions, from his neck being tired of being bend up or down, he will look in the opposite vertical direction.
However, when looking opposite of the secondary direction, something will draw him to look in the same vertical direction as his main direction. Perhaps he’s looking at an arc shaped object in the sky or on the ground, and he needs to look away from it for awhile, causing him to look in a second direction, but when looking in the third direction, he will direct his gaze toward that object again. (Like perhaps a message written in the sky or something). Of course, when needing to look totally away from it can also be done by looking totally in the other direction (and opposite vertical orientation).
His shadow on the ground would basically be looking in the same horizontal directions, but opposite vertical direction. Even though this is hard to see with normal dark silhouettes, it is basically the same image that would be projected by standing on a reflective surface. So the reflections are always looking the same compass direction, but when looking up, the reflection’s head is actually pointing down, which is the reflection of “up” in the reflection, and if looking down, then the reflection would be looking at his “down” which is our “up”.
So you would have a person with one preferred vertical direction, and a primary and secondary horizontal direction. It could be primary East, secondary South, and an orientation of Up. We assume when looking South, he will “give his neck a rest” from looking up, and then look Down. We could use a simple code, U-ES: an Up/East looker with secondary South. Where he is basically a latitude type, looking first along latitude, someone decides that which direction he looks Up in is important, and denotes this by whether it’s the Longitude or Latitude. For him this corresponds, but for another East looker who looks Down in that direction (D-E), the direction he looks up with be the secondary one, which will be North or South; that is, Longitude. So, with “A”=”upward latitude” and “O”=”upward longitude”, we can make this first person’s code USEA. A person who looks down instead would be DSEO. (Since the order of directions [time element] is now determined by A/O, we are free to follow the standard order for direction combinations; S/N then E/W)
We then end up with sixteen “directional types:
USEA: Up, South, East, Lattitude first
USEO: Up, South, East, Longitude first
USWA: Up, South, West, Latitude first
USWO: Up, South, West, Longitude first
UNEA: Up, North, East, Lattitude first
UNEO: Up, North, East, Longitude first
UNWA: Up, North, West, Latitude first
UNWO: Up, North, West, Longitude first
DSEA: Down, South, West, Longitude first
DSEO: Down, East, Longitude first
DSWA: Down, Up, South, West, Latitude first
DSWO: Down, South, West, Longitude first
DNEA: Down, North, East, Lattitude first
DNEO: Down, North, East, Longitude first
DNWA: Down, North, West, Latitude first
DNWO: Down, North, West, Longitude first
