## 7 Conclusions  
Independent and mutually exclusive notions of scale, scope and resolution are provided:  
**Scale**: The set of different symbols used in a description. The scale can be numerically expressed as the symbolic diversity \(D\) of the system's description interpretation.  
**Scope**: The total number of symbols used in a description.  
**Resolution**: The density of symbols (alphabet-symbols or encoded symbols) used to create the symbols used in a description.  
A quantitative conception of scale is introduced. This conception allows for generalizing [PERSON]'s information expression to include transmission systems based on more than two symbols; an expression that may be useful when evaluating the convenience of transmitting information by means of non-binary communication systems. From a mathematical perspective, envisaging the symbolic diversity as the representative value of the observation scale is a convenient result, since it provides an intuitive reason to use the symbolic diversity as the base of the logarithm in a generalized version of [PERSON]'s entropy equation and being consistent with normalized versions [PERSON] (1949) of the original expression. Intuitively, saying a system is observed on the scale \(D\) is like saying the system is viewed from a distance at which exactly \(D\) different objects--or symbols, can be distinguished and from the system's description.  
The scale, the scope and the resolution form an interesting basis to describe the dynamics of our interpretation processes when facing complex descriptions. Considering scale as an essential model parameter reinforces the idea about our capacity of thinking of using our ability to build internal languages with useful symbols. The association of the concept of scale with the number of symbols of the language employed by the observer to interpret a description, offers advantages for the effective representation of complex systems. It also serves as an indication of the mechanisms triggered for our understanding of systems. This is a motivating thought since it paves the road to conceive intelligence as the capacity of finding observation scales--or interpretation scales--which lead to a more effective way of understanding nature and its phenomena. Intelligence, or at least part of it, can be regarded as the ability to find the set of symbols which better interprets a message by means of reducing its complexity and thus leading us to a better understanding of our environment.  
The concept of scale, along with the method for scale downgrading, is also a promising way to compare different interpretations of the same system, as well as comparing different systems at the same scale. The Fundamental Scale allows for the construction of near minimal entropy profiles, which may serve as systems' identifiers. These tools allow for future experiments which may help in our understanding about the interpretation process. The results provide a framework for building useful models to understand our interpretation process, lighting the mechanisms explaining the formation of information from arbitrarily shaped and meaningless symbols.
