Should politicians pursue common ground and reasonable consensus or elusice ideals. It is a goal of politics to searching for common ground and reasonable consensus. However, the pursuit of an ideal is also the goal of the politicians. And most of the time these two issues are not mutually exclusive.The goal for the politics of a nation is to ensure that the nation runs with a minium of contention an develops in a farvorable direction. To achieve it, the politicians need rule out the needs of the majority of its people and search for common ground and reasonble consensus. If needs and willings are frequently ignored, the citizen will resist and make the policies break away practical significance. Futher it does harm to the foreign affairs, since common  ground and resonable consensus are the foundation for people, with different culture to communicate, to cooperate and to make contribution of human. North Keroa is a good count example.Regardless the appearing for peace and harmony, North Keroa is stubborn research of the nuclear weapons. Thus suffered isolated and heavily criticized from the out world, which is do harm to the development of the country. What's worse, not well communicating with other countries in the oversee, and not establish the democratic mechanism in the domestic, it is not hard to imagin how abject and poor lives of its people.However, the ideas of one segment of the public, no matter how vocal, sometimes does harm to the whole nation as well as themselves as a result of their limited knowledge and viewpoint. Therefore, it is politicians who must remain clear-headed facing the need to make right choicews. Before the China's reform and opening up , most people, including the majority of the government officals take it for granted that we should advocate public ownership, and restraict to private ownership, and carryed out planed economy policy. Sounded ridiculous today, but it did exist, even prevail during that period, and it isTeng Hsiao-ping,without him we may still take the stupid view for granted, who reverised the situation. He brought up the reform and opening up policy and market economy, from then on, the economy, the qualiality lives of people,  the national defence and diplomacy of our country has been dramatically enhanced.Most of the time, reasonabkle sonsensus and a political ideal need not be mutually exculsive. Such as an ideal of peace, the desire for a more safe and harmony world, and the pursue for progress. For this similarity, the goal of politics is also the reasonable consensus. Each field need theory to conserve its elite and guild the practice, and every theory need continual refine and innovation, such it is inadvisable to advise a poliotic to stop chasing elusive ideals, which may be necessary for the evelopment of politics. For example, the reform and opening up of China, not only increase the speed  development of economy and people's lives, it also brought about theory innovation,  socialism with Chinese characteristics. Its essence is that we should consider the reality when make any policy and what have been successful  practised in capitalist countries can and should be learned from.In sum, I do disagee with the statment that  politicians should pursue common ground and reasonable consensus rather than elusice ideals. Considering the goal of politics and the limited version of the majority of  people, and the necessary of  ecusive ideads for development of politics, I suggest a comprehensive consideration. Futher, these tow aspects are not exculive  most time, so taking exreme attitute is not a smart politician will do.
