In addition to being a founder of American pragmatism, Charles Sanders Peirce was a scientist and an empiricist. A core aspect of his thoroughgoing empiricism was a mindset that treats all attitudes as revisable. His fallibilism seems to require us to constantly seek out new information, and to not be content holding any beliefs uncritically. At the same time, Peirce often states that common sense has an important role to play in both scientific and vital inquiry, and that there cannot (...) be any “direct profit in going behind common sense.” Our question is the following: alongside a scientific mindset and a commitment to the method of inquiry, where does common sense fit in? Peirce does at times directly address common sense; however, those explicit engagements are relatively infrequent. In this paper, we argue that getting a firm grip on the role of common sense in Peirce’s philosophy requires a three-pronged investigation, targeting his treatment of common sense alongside his more numerous remarks on intuition and instinct. By excavating and developing Peirce’s concepts of instinct and intuition, we show that his respect for common sense coheres with his insistence on the methodological superiority of inquiry. We conclude that Peirce shows us the way to a distinctive epistemic position balancing fallibilism and anti-scepticism, a pragmatist common sense position of considerable interest for contemporary epistemology given current interest in the relation of intuition and reason.

ABSTRACT Although in recent years Christine Ladd-Franklin has received recognition for her contributions to logic and psychology, her role in late nineteenth- and early twentieth-century philosophy, as well as her relationship with American pragmatism, has yet to be fully appreciated. My goal here is to attempt to better understand Ladd-Franklin’s place in the pragmatist tradition by drawing attention to her work on the nature and unity of the proposition. The question concerning the unity of the proposition – namely, the problem (...) of how to determine what differentiates a mere collection of terms from a unified and meaningful proposition – received substantial attention in Ladd-Franklin’s time, and would continue to interest analytic philosophers well into the twentieth century. I argue that Ladd-Franklin had a distinct theory of the proposition and solution to the problem of the unity of the proposition that she developed over the course of her writings on logic and philosophy. In spelling out her views, I will also show her work interacted with and influenced that of the pragmatist who was her greatest influence, C.S. Peirce. (shrink)
