Proper use of conceptual analysis leads to the identification and constructions of models of the world. Concepts are defined for a particular purpose. Generalizing the concepts beyond intended purpose, which is allowed, brings concepts into conflict with other concepts that are defined for other purposes. Conceptual analysis, therefore, should be carried out in a specific purpose to identify and analyze concepts behind words. Formal or informal conceptual analysis is a basic method of determining meanings. Meanings define the human mental models and are an epilogue regarding the limits of formal reasoning. The conceptual analysis comprises of a conceptual graph that is finite connected two parts consisting of concepts and conceptual analysis. Conceptual relation links to concepts (Sowa, 1984). Whereas conceptual analysis can be used properly, they can be subjects to improper use. Improper uses are one that deviates from the identification and constructions of models of the world. Using a network of concepts is an improper use of conceptual analysis. The network of concepts cannot present a perfect model of the world. The world is a continuum and the discrete that are identified and constructed and displaying a network of concepts deviate them from their purpose creating conflicts between conflicts with a different purpose (Sowa, 1984). Another improper is using the perceptual analysis to express an aspect of reality that is fixed. Concepts are inventions of the mind that comes from experience. For this reason, one set of concepts may not be more fundamental or natural than others. One cannot object one concept as false while the other concept as real. Reality is relative and conceptual relativity is a limitation to conceptual analysis. Concepts, despite their usefulness, are not absolute. A person with a notion that concepts are absolute, he, or she focuses only on words. hence, concepts they symbolize miss realities they express. One may use concepts, but he or she should not be bound to them as absolute (Sowa, 1984).
