2.d) Optimization in the human brain structure

Logically, yet against widespread belief, the design of the way the brain operates should tend to its optimization along with the human evolution to take advantage of the available resources in the brain structure. Moreover, we would say optimization is an epistemological principle of any system of vital impulse.

We are not trying to justify the evolutionist or the creationist theory (evolutionism versus essentialism), or more particular philosophical tendencies like animal psychology (instinct as a pseudo-concept), behaviorism, and etiology or, from another point of view, ethnocentrism, cultural relativism, or universalism.

On the contrary, our analysis tries to explain the possible connection or conceptual identity between the present reality of the complexity of the human brain's cognitive functions and the original essence of these vital functions, qualities or capacities by the study of their real evolution and its logical requirements.

If we had to describe our ideas in this subject philosophically, their roots belong to vitalism. That is to say, that the essence of the life implies freedom, intelligence, and memory and that, a logical (non-random) and internal evolution has undoubtedly existed throughout time, and since the beginning of which we call time.

Notably, we can detect in human evolution the following characteristics related to brain structure optimization in both intelligence and memory.


2.d.1. Multiple functions and multiple facets

Although we can use these characteristics as synonyms, we are going to assign them two different concepts or nuances. The multifunctional nature refers to intelligence processes' diverse functions of analyses and information relation. For example, the operations may be aiming to conclude an individual's specific or the result of a mathematical operation –for intelligence usually is the most well-known case. However, it can also operate analyzing and classifying information to store in the different memory levels.

We will also consider the different way intelligence operates a part of its multifunctional nature within the human brain structure, offering somewhat specific responses according to the operative mode. A more detailed explanation related to intelligence is in the book about the intelligence.

Memory also has a multifunctional nature within the human brain structure, although there are differences regarding the intelligence brain structure. We can cite the different types of memory as regards to the temporal horizon with which it works: instantaneous, short, medium, and long term. Likewise, this nature of memory we will see in more detail in the book about the memory.

We understand its multifaceted nature as the different subject to which both memory and intelligence can be applied. For example, apropos intelligence, we can cite, among others, spatial, color, and auditory relations, logical abstraction, and multiple characterizations.

Moreover, as far as memory is concerned, we can mention information related to images, abstract concepts, linguistics, and colors.

We can explain these characteristics using computers as an example. As previously mentioned, the central processor is used as much for the treatment of information as for its localization, and, at the same time, to execute programs of diverse natures. About computers, there are various types of information support, and multiple subjects to store.

For intelligence, this multifunctional and multifaceted nature allows us to delve slightly deeper into its content or definition. We have mentioned that we understand intelligence as a capacity to relate. Therefore, the group of abstract and elemental relational functions that allow all reasonably complex operations to be carried out is what form intelligence.
