The Plant

Knowledge grows like a plant cultivated for its fruit or like an animal raised for its meat. At the right time they both give up their existence for our nourishment and survival. Both live and survive in nature but both have been adopted to support our physical existence. In the end, both give up their being for our human intellect.
It's is our intelligence that recognizes our surroundings and as individuals we try to understand our existance by recognizing patterns of life around us. Our need for food has been dominated by our ability to recognize patterns and adapt them to a communal existance.
Adapting patterns is an individual's work but as the perceived pattern is shared they become something else. For our existance they combine space, time, scale and mass; taking a form that exists in the reality of many people. It is a natural process unique to our existance.
Eisenstein developed the mathematical formula E=mc 2 (square) - it existed in our perceptions prior to his formula but it was not integrated into our human knowledge. However, once the pattern was defined in such a way that it was understood and accepted by a great many people as being true then it was understood as part of our shared reality.
All human knowledge moves through stages of development and evolution that begins with our senses - if we use them.
