In this sense, the relationship between mind and body is analyzed, presenting this phenomenon as a mental state that receives interferente from chemical reactions that occur in the human body. We also analyze how this interferes in the manifestation of this phenomenon. In addition to this aspect, it is emphasized the role that structuring and training play on the manifestation of conscious perceptual perspectives, in which they are recognized as relevant to the phenomenal adaptation. This dialectical dynamics, which takes place in between the mental events, contributes for the viability of the adaptations of perceptual perspectives, according to which human beings perceive the world and operate in it. In this work, we therefore seek to understand how the quest for survival and its maintenance, as well as the achievement of the needs raised by society and the search for knowledge, operate like demands or subjections that provide adjustments in one's conscious perceptual perspectives. / O presente trabalho investiga a ocorr?ncia do fen?meno da consci?ncia humana a partir da base biol?gica e tamb?m sob o influxo de fatores socioculturais e de componentes existenciais. Analisa-se, nesse sentido, a rela??o entre mente e corpo, apresentando esse fen?meno como um estado mental que recebe interfer?ncia das rea??es qu?micas que ocorrem na base corp?rea humana e como isso interfere na ocorr?ncia desse fen?meno. E al?m desse aspecto, ? destacado o papel que a estrutura??o e forma??o exercem na manifesta??o de perspectivas perceptivas conscientes, em que os mesmos s?o reconhecidos como relevantes para a adapta??o fenom?nica. Essa din?mica dial?tica, que ocorre entre os eventos mentais, contribui na viabiliza??o das adapta??es das perspectivas perceptivas segundo as quais seres humanos apreendem o mundo e operam nele. Procura-se, desse modo, compreender como a busca pela garantia e a manuten??o da sobreviv?ncia, o preenchimento das necessidades suscitadas pela sociedade e a procura e/ou aprofundamento de conhecimentos estariam a operar como demandas ou sujei??es que propiciariam adapta??es nas perspectivas perceptivas conscientes de uma pessoa.
