The purpose of this paper is to explain what the“ third wave” of science studies is. First, I will explain the scheme of the three waves of science studies. Next, one of the main components of the “third wave,” “expertise studies,” will be introduced with examples to show what lessons it can bring to us. Then, another main component of the “third wave,” “elective modernism,” will be discussed, using concepts such as the “formative aspiration” of the scientific community to explain why we should choose science as our standard of knowledge. Finally, how science should be positioned in relation to democracy in our society is discussed, and a new expert advisory system called “the Owls” is described.
