Since Platon, the primacy of the common good on the self-interest has been a great interest for political theorists. Beyond the breaking of considerations on the politics that we notice today, many thinkers remains unanimous on the event that as Saint THOMAS said: “The social life finds its unit and its aim in the research of the common good” This work allows us to understand the common good as an objective politics to Julien FREUND. For him, the common is principally the total collective good in which individuals are integrated as members who attribute to themselves a state as institution. The common good is not to be confused as the privates neither to the amount of common good either of individuals or subordinate groups, these families or any other professional asocial nor to the state property as a state. The common good as aim of politics is insured to citizen when a leader insures the exterior security and the interior harmony. That is why Julien Freund considers that the government activity consists essentially though not exclusively on the collectivity defency against any possible attack. If the security tends essentially towards the life conservation of the collectivity, sometimes on the price of sacrifice, the interior harmony of the collectivity allow to citizens to find a reason to live practically and spiritually. However, for all time, it had been and remains the best task of the politics to organize the city as harmony as possible, according to the idea which seemed to be the best for giving to people, to a purely economic level, the possibility to satisfy well the need that they needs that they had experienced. Having the needs of achieving to the common good, Julien Freund considers the combination of strength and cunning. Indeed, he considered that cunning is the political mean of the civilization and the strength is the one of the uncultured. It’s that he expresses in this manner: ”The history is frequently seemed to be scorned towards chiefs who had survived only by brutal strength and barbaric and by killing many persons, slaughter and massacre while it vaunts the calculator and clever chiefs address who had triumphed to the favor of the cunning and the mischievousness”. To end, invited to manage the destiny of the daily activity, a politician can’t go beyond the moral. However, the choice of means in politics and the political responsibility is incumbent upon the first chief of people who hold the power.

The political and economic crisis that the Democratic Republic of Congo is faced to nowadays after fifty-six years is worrying to the extent that it is increasing. Violations rights are mentioned day to days in every corners of the country. International N.G.O. never stop reporting balances of violations and sometimes they are contested by authorities of the countries. Congolese citizen finds that he is very embarrassed and lived in bad condition in his proper country without a better future. The consequences of that crisis are considered differently according to social position of each citizen. To authorities we mention a fair of future, instability of actions and remedy to antitrust as lie, corruption, embezzle of public funds, fallacious promises… To people, ignorance of rights, fanaticism, fear is added and increase misery which a large party of population is plunged in. Face to that disconcerting politico-economic situation, the look of the way to go out becomes an obligation for every Congolese. It’s in this case that is intended this research that its foundation is philosophic. We consider that the crisis problem in the DRC is reliant of the loss of realistic political engagement which could consist: - To leaders a culture of true, sense of service and respect. They have to consider the power, not as career but as warrant to use for a profit of all citizens. - To citizens, to engage with courage, without fanaticism to fight injustice and violation of their right. - To International powers, to lead the democratic process by knowing that Congolese are able to take charge of their situation. Then, International powers will avoid imposing themselves in politic life of the Democratic Republic of Congo.
