It emphasizes subjects as the individual, choices and the nonsense of the life human being when contemplating a rational understanding of the universe (Blackburn, 1997; Cabral, 2006). The first philosopher who if really affirmed as existencialista, that assumed this denomination, was Jean Paul Sartre (Borheim, 2005; Cabral, 2006), but, for some researchers, existencialistas characteristics can be perceived in the writings of diverse authors, amongst them: Kierkegaard, Heidegger, Marcel, Jaspers, Unamuno, Abbagnano, Chestov, Camus among others (Borheim, 2005; Vicente, 1885, v.05). How much to the existencialistas workmanships, generally romances, these, on the other hand, react against the point of view of that the Universe is a closed system, coherent and intelligible; however on the other hand, they see the uncertainty resultant of this paradigm as an affliction reason. It was in this context that Jean-Paul Sartre pointed out in its writings the importance of the freedom human being and, in consequence, its freedom moral. Still for Sartre, the existencialismo is the only doctrine that leaves a possibility of choice to the man (Sartre, 1987). When defending this affirmation, the existencialistas mention the fact to it of that, to its to see, during the existence, each one constructs its proper essence (Cabral, 2006).
In accordance with the writings of Sartre (1987), ‘ ‘ The man nothing more is of what what it makes of itself mesmo’ ‘. In this way, Blackburn (1997) and Cabral (2006) corroborate when affirming that the workmanships of Sartre have matrix of exploration of tension choices and can sociopoliticamente be considered with the period where they had been written. The existencialismo concentrates its studies in the man concrete, limited for the time, searching a direction it its life.
