How are the Norms of Human Reasoning Possible——Towards a Peircean Solution

Before addressing the question of "What are the norms of reasoning?" there arises an epistemological inquiry:"How are the norms of reasoning possible?" The feasibility of normative regulation in human reasoning, which entails evaluative distinctions between good and bad reasoning, might be taken for granted by most logicians. However, some arguments against it or at least doubting it in a somewhat pessimistic tone are gathering in contemporary philosophy of logic. Charles Peirce, an early founder of modern logic, grappled with the profound issue of how the norms governing reasoning are possible. His theoretical framework concerning logical reasoning not only offers a distinctive approach to demonstrating their possibility but also contributes to resolving contemporary qualms surrounding the normativity of human reasoning.
