It is important what it has practical character, useful and only satisfies the desires immediate, what it does not take care of to these questions is placed to the edge, it is not important, he is discarded. Therefore the question of the pleasure, as much in the hedonista thought how much in theories of Condillac, they permeiam the reality and they act however as mantenedores of the life, however as its annihilators, therefore good or the bad one of the pleasure inhabits in as if it looks for and until where it arrives and all the extremities are inconvenient, the pleasure excess invariably is become into vice. The escape of the displeasure As well as Hobbes and Condillac, Freud also relates the question of the sensations as originary of the thought and the actions of the human being, however if Hobbes locates the desire in the top of hierarchy of the passions and Condillac places the pleasure in this position, Freud has a particular vision of the pleasure notion, therefore it relates and any desprazeroso stimulaton all as something. The stimulatons are had by Freud as what desestabiliza the nervous system, therefore this desires ' ' repouso' ' , then all sensation is associated with the disequilibrium of the system that must ' ' to drain all carga' ' that it receives from the exterior, keeping the minimum of energy to only take care of to the internal stimulatons and thus to give maintenance to the organism. In this direction, Freud, exactly having as theoretical base the ideas of Condillac, dislocates in the hierarchy of the passions, the pleasure to an inferior position, it reduces the passion, the desire, the pleasure what it brings discomfort to the organism and that, therefore must be prevented, that is, the opposite of the status that these sensations enjoy in the ideas of Hobbes and Condillac, that they claim to the search for the pleasure and not it escape of it.
