Different forms signify different possibilities and potentials on many different levels. The number of protons causes some things on some levels by virtue of its topological potentials, but that is not the cause of order in the the cosmos, or awareness. Gold could be any number of protons in a nucleus, it just happens to be using that configuration, just like the ip address of a website does not determine its content. > What led you to chose the chemical elements as the origin of sense and > feeling, as opposed to higher level structures (neurology, circuits, etc.) > or lower level structures (quarks, gluons, electrons)? > The chemical elements have nothing to do with the origin of sense and feeling at all, just like the letters of the alphabet have nothing to do with the origin of Shakespeare.

The complexity of presentations and representations contribute to each others complexity and allow both to become more elaborate, but in an ultimate sense, the presentation is driving the complexity rather than the other way around.
