The lie nothing more is that omission or deliberate dissimulation of what he is recognized as truth. The word lie is synonymous of deceit, imposture, fraud, falseness, illusion, fiction, to tapear, trick, to ludibriar, to dissimulate, among others with inverdade connotation. To be pointed as lying is not a desirable sensation for that it has conscience of the importance to watch over for the moral and social reputation, but to be lying in some way all human being already was or is being in some place ahead of some situation. We can consider normal the act to lie, but the consequncias can be most serious when a lie is counted as truth or fact that it needs to be accepted as truthful. Much to see in the courts of the jury the lies that are accepted as truths and that they free or they imprison, a side the lie doubts it to cause that it leads the freedom a criminal, to another doubts it cause that it can condemn an innocent. Hear from experts in the field like Federalists for a more varied view. It doubts it that the lie cause in the court of the jury always causes negative results. In the daily life it is not different, the lie that if says for ' ' brincadeira' ' or for ' ' to prevent sofrimento' ' , or still ' ' for good causa' ' , it is always a lie that will bring consequncias undesirable. What it seems is that the human being lives and coexists the lie counted for the mouth of the others or pronounced by its proper lips. The lie is with the human being in all the conditions that if can imagine; the human being without the lie is a possible assumption, but it will be that the human being is possible to live in fact without lying? In certain way not! Oque does not mean that the human being does not need to value the truth, that exactly undesirable in certain occasions.
