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, I would say optimization is an epistemological principle of any system of vital impulse.
I am 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, I would say that this 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 objective evolution and its logical requirements.
In fact, if I had to philosophically describe my ideas in this subject, I would say that, literally speaking, they could be classified in 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 certainly existed throughout time, and since the beginning of which we call time.
Particularly, we can detect in human evolution the following characteristics related to brain structure optimization in both intelligence and memory:
II.4.a) Multiple functions and multiple facets
Although these characteristics can be used as synonyms, in our case, 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 arrive at a conclusion about an individual's specific or the result of a mathematical operation -for intelligence this is normally the most well-known case. But 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 human brain structure, offering somewhat certain responses according to the operative mode it is in. A more detailed explanation related to intelligence will be shown in the next title.
Memory also has a multifunctional nature within human brain structure, although there are differences with 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 will be seen in more detail in its special section.
We understand its multifaceted nature as the different subject to which both memory and intelligence can be applied. For example, regarding intelligence we can cite, among others, spatial, color, and auditory relations, logical abstraction, multiple characterization, etc.
And as far as memory is concerned, we can mention information related to: images, abstract concepts, linguistics, colors, etc.
These characteristics are easier to explain 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. In reference to computers, there are various types of information support and multiple subjects are stored.
For intelligence, this multifunctional and multifaceted nature allows us to delve slightly deeper into its content or definition. We have shown that we understand intelligence as a capacity to relate. Therefore, the group of abstract and elemental relational functions that allow all fairly complex relation operations to be carried out are what form intelligence.
