Edge Behaviour

What follows is an excerpt from a paper by Yuri Milov. Basically, it's saying there are 'edges' between the real, physical world, the mentally perceived world, and the world of ideas. Interesting things happen at those edges.

METAPHYSICS:
Existential Cycle
A tradition in perceiving our world as a relation between three independent worlds has recently received some new development. Roger Penrose [5] considers three worlds and relationships between them. One of the worlds is the mental world of the person. It is objective and real. Another world is the objective physical world. The third world is Plato's world of ideas, mathematical structures, absolute truths, etc. In the mental world there are real "things" and "phenomena".

For example, there exists happiness and pain, smell and colour, love and understanding, impressions and images of stars, tables, chairs, etc. In the physical world there are the real tables and chairs, sun, stars, stones, flowers , butterflies, space and time, molecules and atoms, electrons and photons. The Platonic world also has real existence, as well as the two previous ones. Ideas and mathematical structures exist in the same sense in which things really exist in the physical world (under the physical laws) and images, feelings and imaginations exist in the mental world (maybe under psychological laws). The crucial question is how are these three worlds connected?

Firstly, physical reality submits to laws of nature that have an exact mathematical form. Physical reality would seem to be born in the body of mathematical structures. Secondly, real physical phenomena and bodies create the mental world (at least in the form of human consciousness). Thirdly, ideas, concepts, and mathematical theorems have to be discovered in the mental world to continue their "independent" existence in the Platonic world.
