Starting out as a "method of dimensions" to create "tight" specifications of information requirements, what started out as Locational-State has slowly developed as an approach which has gradually uncovered a theoretical foundation. Euclid, Alfred Korzybski, Minkowski and others have produced theoretical and applicable perspectives in physics and other spheres where space-time is expressed as a 4D model. However, there is an urgent need to model physical objects and their relationship to the environment within which they exist in a practical way so as to draw useful conclusions. For this there is a need for a more mundane but practical description of this compound expression (space-time) to enhance comprehension and thereby its utility. On the other hand it is of little use to elaborate a template or simple recording format that bears no real relationship to the locational-state imperative1. So we are faced with developing a practical theory of relevance. Truth is, as William James observed, "what happens". If the works of Charles Peirce, Willian James and John Dewey are reviewed we enter the domain of pragmatism where this is defined as the theory of truth. Locational-State never started out with the pretension of contributing to this fundamentally important discourse but, as research into Locational-State continues, this, it would seem, is what it is doing.
Several, relatively recent developments have helped place Locational-State in a context of increasing relevance as well as helping it become a combination of robust theory and practical utility. These are the works of George Boole in his development of a mathematical logic designed to explain how individuals deduce (The Laws of Thought published 1854) based on experience of events (probabilities) and releationships (determinants). Claude Elwood Shannon, whose 1938 paper, "A Symbolic Analysis of Relay and Switching Circuits" explained how Boolean Logic and the process of Boolean reduction could contribute to a more efficient circuit design. This seminal work launched Boolean logic into the digital world.
In the digital world, as early as 1960s, Kristen Nygaard and Ole-Johan2 became concerned with representation of heterogeneity, that is, to be able to describe and simulate reality. They developed Object Oriented Logic to address this issue and used this to build the SIMULA series of computational simulation programs. Ronald Howard, of Stanford University, also in the 1960s, coined the term decision analysis and created a strict dependency between the quality of determinant models, information or data quality and the probability of events resuscitating the fusion between George Boole's concern with experience and "what happens" with probabilities and questioning (decision trees) to refine the quality of information relied upon to deduce and take decisions. Roger Kaufman related systems operations design and objectives to user or constituency needs based on a broader consideration of the sustainability of the system (our world) while relating this to the details of the processes used by economic and social constituents.
What is lacking, quite often, are comprehensive descriptors and analytical methods that can be used to make a more effective decision analysis simulation models based on Object Oriented Logic and that integrate systems sustainability; locational-state theory has a major contribution to make in this area.
1 According to McNeill, the locational-state imperative (LSI) is the essential qualification of an object property in terms of its formative history and current environment and ecosystem. All phenomena are subject to this qualification. Data that lacks effective locational-state qualifiers is of a deficient quality. The LSI is an essential qualifier in relation to living organisms including people and relevant to agricultural production, biomedical spheres, natural ecosystems and biodiversity.
2 Object Oriented Logic (OOL) was developed as a way to program computers with a programming logic known as object oriented programming (OOP). This was first developed in the 1960s by Kristen Nygaard and Ole-Johan and who until their deaths worked at the Department of Informatics at the University of Oslo, Norway. Their objective was to address the problem of simulating reality when reality is characterized by heterogeneity. This they achieved with the simulation program SIMULA the first object oriented program in the early 1960s.
In agriculture, one of the most complex heterogeneous systems in the economy, the best approach to the identification of essential data for policy making is to deploy OOL. This is a rational approach since the relationships between critical variable elements of OOL is Boolean Logic which is the mathematical logic of how humans analyse and deduce. This is based on known cause and effect relationships, recent experience and access to information and our view of the probabilities of events. These are the basic factors deployed in human decision analysis
