Political ethics can be simply defined as the rules of mutual treatment among people in the political activities, or norms to be followed by people in the political arena. Confucius said, ”He who exercises government by means of his virtue may be compared to the north polar star, which keeps its place and all the stars turn towards it.” This is a good example of exposition of political ethics. The ancient Greek philosopher, Aristotle, classified politics and ethics as practical philosophy, regarding both studies not only as a branch of human knowledge, but also as a practice to be realized in human life. These two subjects are interrelated to each other, because ethics pursues the highest good, i.e., happiness of the individuals, while politics pursues the highest common good of the polis or the whole society. Both aim at the highest good, and happiness, but politics ranks the highest among all subjects. The paper consists of four parts. In the first place, we shall try to define what political ethics is and also its scope. Secondly, we shall try to expound the relationship between political ethics and political culture. Thirdly, we shall try to select some basic issues in the political ethics. Fourth, and in conclusion, we point out that the study and the education of political ethics is an inescapable element in building up a sound democracy.
