Abstract
The rationality of the human being applied in science-technique in the contemporary capitalist system is distorted; the purpose, which is the good life for human beings, has become the means to sustain and feedback the technicist system of technological capitalism. Thus, the modus operandi of science, aims only to legitimize technology, apart from the ethics applied in this relationship between technology and human beings, and cut off from critical philosophical thinking. With the result presented, the problem lies in the reason of the contemporary human being, who seeks to satisfy his desires and envisions the good life (eudaimonía) in material goods, suppressing the contemplative leisure of life (ataraxia); becoming a slave to the system it fosters. The objective is to demonstrate the need to reformulate the modern system, in order to earn a good life for human beings as a purpose of technical science, which should be the means for this and as technological advances in favor of the quality of human beings. and, not for capitalist reproduction. The research methodology is an exploratory bibliography, exposing and dialoguing with authors on the subject in order to forge our conclusion, that pleads for science-technical that enjoys ethics and human reason in favor of eudaimonia.
