This paper aims at discussing Max Weber's methodology, specifically based on his essay "Objectivity in Social Science and Social policy". It is well known that Max Weber made continuous efforts to construct modern social science; his Gesammelte Aufsätze zur Wissenschaftslehre are full of highly suggestive ideas and concepts for students who are interested in methodology generally. If media studies is also expected to be one of genuine social and cultural sciences, every piece of Weber's thought will be important. Every social reality is unique, concrete and infinitely rich; we cannot grasp it without constructing "ideal type" which is not real image of reality, but its edited one. It will be shown that Weber's "ideal type" is composed of three ingredients, that is, economy, value and history.
