Hey, no problem, let me try and be clearer.
When we describe something, anything, there are different ways we may choose to describe it. I may say there is a cup in front of me. I have isolated the object 'cup' with my language.
I could also say there is a yellow patterned fired clay cylinder closed on one end and open on the other, with a curved hollow protuberance (the handle).
In the first instance I summed up that information with one word cup, because that was all that was needed to communicate the idea. There was also information loss. I did not say the cup was yellow, that it had a handle, that it was fired nor that it was patterned.
Local Level 1: Cup - a function
Local Level 2: The description of the cup
I could also look at the arrangement of the atoms. What type of atoms they are, how they are bonded, what conformation they take inside the cup. I could become very specific with my description of the atoms and the angles the bond configurations take as the cup takes form. Lots and lots of information.
At the level of the cup there are other objects about, such as myself and the desk. These also can be described at different local levels. When we say the man picked up the cup off the desk and we describe this in terms of atomic configurations and relative movements through the atoms in the air, the electrostatic bonds with my hand etc it is extremely complicated. It is best to use semiotics (the man lifted the cup off the desk).
It seems almost absurd to describe the action in terms of atoms, and yet, there is nothing else there. It is all atoms. Everything else is semiotic description. (OK even atoms are and we can keep regressing).
When we realise this, a Holy Cow moment comes over us - or me at least. What guided that? How did the atoms coalesce to create this complex phenomenon. In this example I have used things made by man rather than life or natural inanimate object interactions, and so it may seem a bit mundane, but the point I hope is clear:
When we back out of our local level and look at what is truly going on we find the security of semiotic understanding is removed. We begin to search for the fundamental driver of the action.
