It seems? in the revealer the analogy that Rousseau traces between the natural regularity and the social one. What it wants showing in them? What this means? Rousseau ironically wants in them to indicate the nature of the corruption and of the decay, that is, he is ' ' natural' ' customs to be corrupted when the man if disnaturalizes, when the social inaquality is converted into ' ' natural' ' very for this contributes arts and sciences in reason of ' ' hunger of vaidade' '. The nocividade of the vanity consists of the attachment to the comparison in relation other had people as inferior, or as it explains N.J.H. Dent in its Rousseau Dictionary: ' ' the desire of the individual vain to measure in relation to others and of congratular themselves for its anteriority on them is, in understanding of Rousseau, one of the most spread out human desires in society, although to be deeply harmful in such a way for the perpetrador how much for the aimed at one for atitude' ' (DENT. 1996, P.
208). Nowadays we could say that, for Rousseau the vanity creates dependence and while such is one ' ' drug social' ' that it becomes the muddy sight hindering that we enxerguemos the man as it is. Therefore to enxergarmos the man in its moral perspective is necessary to desvencilhar? if of ' ' books cientficos' ' , therefore in they supply fallacious, representative knowledge to them on the man. In this direction sciences would be a powerful and efficient instrument of legitimation of the inaqualities, valuing pleasant knowledge in depreciation of that they can bring benefits. Science: a problem. In contrast of the enciclopedistas that turn the cientificidade as solution for the problems the man, Rousseau has the conception of science to consist in problematic way. For reason of the degradation, the inaquality and the dependence for vanity that it provides to the man.
