People’s strong opinion that they are entitled to certain rights dates back from ancient times and has crossed the whole history of mankind. "The idea that the human being possesses by its very nature certain rights that are valid even if they do not correspond to them, or they correspond in an imperfect manner to the provisions of the positive juridical laws”, appeared in the human mind in ancient times being then transmuted in wise words by the stoic philosophy and jurisprudence, in all subsequent ages sometimes inspired by the doctrines of Christian religion, sometimes only out of the light of rationality. Individual freedom is the fundamental right of a person, derived from the natural right of the human being. Despite the vocation of great political ideologies of the XXth century, man is more and more trapped by a social system in which the mechanism and means have come to prevail over the object and the ultimate result. The autonomy of managing personal life and the right to individual action only stops where this form of will violates the legitimate rights of other individuals.
