Whiggish historiography takes modern achievements of present sciences as scales to judge the importance of ancient sciences. Whiggists divide history into two sides: good and wise scientists vs. bad and ignorant ones. They study the history of science to find the winners, with present-day criterion of "true" scientific claims. This paper firstly introduces Herbert Butterfield and his book on Whiggism. Butterfield in Whig Interpretation of History discusses and criticizes the idea of Whiggism as a deviate course in general historiography. Secondly, some examples from the history of astronomy will be presented and the issue of Whiggism in the historiography of science will be considered. The paper will be closed by some suggestions to avoid Whiggism in the history of science, and to what extend it is legitimate to use it.
