**6. Conclusion**

Truly a designer can assign determined values to the arguments or weights in cause and

Hence Design is no longer a derivation from art, not even from object engineering (MOURA, 2012). Design can be what informs about human creativity, that emerges from the combination and interaction between the several fields of creativity itself, to what we would like to add that it depends on the combining of different arguments and weights of the system of beliefs to what that designer pertains and that will always be the one he received in its School as a

We here designate as pertaining to a same school all those who share the same arguments with

Hence we can state that we can have as much Schools or Systems of Beliefs as the nature of

with the same weight allowed to the same arguments:

The result is that a System of Beliefs is a School, a cluster, and it shares the same arguments

Hence we can deduce that Schools have the gift to simplify things. And that the set of data or arguments is equal to *1*. Naturally the better the School the less data it will need to explain or

In conclusion, some aspects can be evidenced:


In conclusion we can also state that Maeda's laws are not effectively laws, but methods or suggestions to define simplicity, because as we saw the simplicity measure explained does not need further increase.

Hence, if we use this relativist measure for simplicity coupled with the complexity measure, we then have the quantitative parameters that release us of qualitative laws for engineering or for design. They allow us the necessary amount to assess design, or engineering, or both.

Therefore the encounter between complexity and simplicity is an art, once we are capable of measuring it and, as such, to quantify it, we acquired the necessary tools for either an engineer or a designer, to achieve the objective of conceiving and build concepts, methods, processes or products, either organic or functional, and hence, at the very end this is what an engineer or a designer aims to. Complexity and simplicity is an art over which we are capable to put measures and, as such, to quantify.

In conclusion we dare state that if we were in the presence of a philosopher; he would say that the true definition for simplicity would be: it exists as to make sense within the world that surrounds us.

It will be then demonstrated that "Simplicity" (its measurement) in particular that of Design, being measurable, is also an Engineering parameter.
