This because, to if dealing with an intellectual project, diverge opinions, being able to be considered since instrument for greater reach to be able on the part of the elites to powerful ' ' arma' ' of revolution of the popular layers. The sprouting of such science in sends the centuries behind to them, when the feudal society lost space for the capitalism and thus innumerable problems had appeared, such as unemployment, laboring illnesses and revolts, which would unchain a bigger analysis of the society and the search for one better social organization. These problems had after appeared double occured revolution in the Europe of century XVIII, in special and Industrial Revolution, that led, to the few, the society to the category of ' ' problema' ' to be investigated.
