  "Ge She Zhi Zhi" is a novel saying in Chinese, stated as "To investigate
things from the underlying principle(s) and to acquire knowledge in the form of
mathematical representations". The saying is adopted and modified based on the
ideas from the Eastern and Western philosophers. This position paper discusses
the saying in the background of artificial intelligence (AI). Some related
subjects, such as the ultimate goals of AI and two levels of knowledge
representations, are discussed from the perspective of machine learning. A case
study on objective evaluations over multi attributes, a typical problem in the
filed of social computing, is given to support the saying for wide
applications. A methodology of meta rules is proposed for examining the
objectiveness of the evaluations. The possible problems of the saying are also
presented.
