On the basis of the Brazilian Constitution, and focusing on fundamental rights, on liability, on the rules and principles system theory, while considering the undeniable fact of the constant evolution of the use of the Constitution, as well as the sum of its parts in an attempt to better explore the legal field, this thesis will have as its solid base the clear human evolution. However, it would be neglectful not to mention that such systems and its consequences provoke serious issues and controversies, especially in the judicial sphere and in the fields of psycho-social behavior sciences and law. Indeed, such functional evolution involves all cultures and peoples, as well as world evolution itself, on the one hand facilitating human coexistence in accordance with norms that regulate the social context, but on the other hand, at the same time restraining and exacerbating individualism. Consequently, people bound or subject to said norms may suffer some kind of loss or damage that will be understood and judged according to the interpretation of the constitutional rules and principles, as applied to the fact at issue and the individuals involved. In this context, the present study analyzes, in general lines, the effect of the evolution in the use of the Constitution and the attempt to sum liability, rules and principles of the Constitution and its interpretations as applied to human behavior in the individual and social environments, as well as the structuring of law in these conditions and the legal support for the described situation.
