Can't a piece of a thing be a thing?
Then all things wouldn't be one thing. They would be one thing and separate things. This is complementarity - Perspectivism. One will see what one will see based on the manner in which one looks. All the action is still in the realm of thought an language in either case though, isn't it?
By what means do we apprehend, comprehend, organize and define
our reality? Fundamental to language, though largely unperceived in its ordinary use, we form the reality of things and motion through
relation. Things are understood, categorized and remembered according to categories of traits and uses stored from other things remembered. We recognize motion of objects from change in their position relative to other identified objects. Put simply, this is the only manner in which language, thought and the logic of "things" works.
Signs and symbols cannot capture the whole truth of things and motion, or causes and effects. The mere act of carving out of reality discreet things in relation to other things, and identifying discreet motion relative to other things, although quite useful to enable more mastery over my environment, detaches them from the complete whole of which they are a part. For example, to a boy eating an apple, the single identified fruit is a useful object. That same apple from the perspective of the grocer is merely part of a bushel of apples. That bushel (which contains our apple) from the perspective of the grower is part of his orchard. The orchard to the environmental planner is part of the development plan for valley . . . and so on. Which perspective of the apple is the true one? All and none. It depends on the use to which the apple is being put. And changing the perceived truth of the apple can be accomplished merely by changing perspective.
