This thread contains section 2 and part of section 1 of a 5 section paper I'm writing regarding consciousness. Section 2 is intended to create a more general theory around something used in engineering called "control volumes". I've also included part of section 1, the abstract, to provide a bit of an introduction to the concept of control volumes. Since the post is rather long, I've broken it into two posts. I'd like to get feedback on: 1. . the overall paper. General comments and questions are welcome. 2. . where there might be better philosophical terms or concepts that could be applied to and incorporated into the paper. Are there for example, any existing concepts like this one, and if so what are they? I'd very much appreciate any applicable internet sites you can offer. 3. . what references need to be included. The paper has a number of foot note markings such as  which are intended to mark existing concepts and where references might be included. If you have any suggestions as to what those references could be I'd appreciate the help. 4. . any suggested rewrites. Feel free to pick apart any section and rewrite it.

Very similar forms of the concept have been created and applied to almost all areas of engineering and science. These concepts have gone by a variety of names such as "finite element analysis ", "free body diagrams [2a]", "nodal analysis [2b]" and other names. Such concepts are used as tools to reduce a larger two or three dimensional space to small chunks. The concept stems directly from the concept that any system can be reduced and any phenomena which 'emerges' from such a collection, must also emerge from the collection of control volumes. This paper is intended first to generalize and expand on the concept of control volumes to the point it may be applied to any and all physical interactions. To achieve this goal, a method of applying the theory for all possible physical interactions will be proposed and outlined. The theory is based on the reductionist philosophy that anything can be broken down into its constituent parts, along with the causal relationships operating on those various parts, and the function of those parts can explain any and all phenomena which evolves. Control volume theory may be applied to both real, physical entities and imaginary mathematical entities. The theory is applicable to both, it is not just a mathematical tool. When used as a mathematical tool however, specific mathematical relationships used to model physical laws have been excluded from this paper. It is left to others to determine how best to apply the theory where it may be of use as a mathematical tool. Such a task is beyond the scope of this paper. This theory is intended for application to macroscopic volumes of space and matter only, and not exceedingly small parts in which quantum mechanical interactions might play a role. When referring to "macroscopic volumes of space and matter" what is being referred to are three dimensional volumes of space or large enough chunks of matter within which quantum mechanical interactions are thought to have no significant affect, such that one can make accurate predictions regarding the time evolution of the space and matter under consideration. Once the theory has been fleshed out, it can be used as a tool to examine any given mechanism to determine if a phenomenon can emerge from the interaction of various macroscopic volumes of space and matter. This is essentially a reductionist's tool, though it is limited to relatively large chunks of space and matter under relatively common conditions where quantum mechanical affects are not needed to determine the time evolution of those chunks. It may be used where only strict causal relationships between those chunks need to be considered.
