According to Peirce, normative sciences are the “most purely theoretical of purely theoretical sciences.” At the same time, he takes logic to be a normative science. These two sentences form a highly interesting pair of assertions. Why is logic among the most purely theoretical sciences? What does it actually mean that logic is a normative science? This chapter answers these questions by addressing the question of why the normativity of logic is, as a matter of fact, based on rules.
