Some thoughts from my Thesis note book...
A rock has it's own presence and purpose as well as a hard drive. I use rocks in the same way that I use hard drives as storage devices for past experiences. I have a unique understanding of the two individual objects, in the hands of another the meaning may change. The uniqueness there for is not a physical attribution of an object but in the meaning an individuals connects to the object. Leading me to the conclusion that the power of knowing is not in the objects themselves but in the mind of the observer that creates new meaning and since we are all uniquely experiencing the objects then our understanding will differ slightly from the next.
The physic experiment where you have a pond and two people with rocks on opposite sides of the pond drop their rocks into the water and wait for the ripples to meet each other in the middle. When they do meet new patterns are formed. Each drop of the rocks will create new patterns each unique. I think the space in the middle of the pond metaphors what I am writing about above, it is the space of the observers mind.
