Abstract

The debates about qualia are common in contemporary analytical philosophy, especially in the area of philosophy of mind or epistemology. Notwithstanding the significance of this notion in present-day investigations, there still appears to be a lack of agreement over how to understand the term “quale”. Due to this fact, our goal is to shed light on the concept of quale as it entered the modern history of philosophy. Strictly speaking, our concern shall be devoted to the American pragmatist philosophy of C. S. Peirce and C. I. Lewis. Therefore, we intend to outline the understanding of quale within Peirce's theory of categories at the beginning, and afterwards we shall present Lewis' remarks on quale in the context of his theory of the given. This approach will not only provide the grounds for relating Peirce's and Lewis' views with each other, but also it will let us interpret Lewis' notion of quale within the pragmatic framework.
