This can be seen in space as well, there is no up down left and right or north west east south unless you say there is, therefore there is, hence such thing's as that only exist because "you" or "another" say's they do, therefore you make them have an existence...:rolleyes:
You could see it as human's making lable's for the system of are existence.
Tool's must be labled to share them with other's...
(hence such concept's are mearly tool's to share perception)
(yet every tool has a purpose and an oppisite purpose to it)
Not to say I disagree with your conclusions, but there is some physical quality associated with north and south, as the rotation of the earth, and the magnetic poles of the earth, and that it is North and South as opposites which give East and West their meaning, because from our perspective, on a flat earth, we need to orient ourselves. With moral opposites we orient ourselves in regard to others without a true physical reference point, which often means that we have found a very undistiguishing point by which to distinguish ourselves. If we talk about people we should first realize that we are not opposite to each other, and that word labels like good and bad, white or black, right or left, wrong or right, all serve to alienate each from the other, and should be used sparingly if at all. People are people and we all have similar if not identical needs. Some have different abilities, but geniuses are as common as idiots, so we should all try to get by and help each other. imo. Thanks
