This thesis develops Dewey’s theory of inquiry and provides a novel perspective on what realists consider to be Dewey’s most controversial claims: his rejection of the view that inquiry aims at providing an accurate representation of reality, his claim that the object of knowledge is constructed, and his definition of truth in terms of warranted assertibility or fulfilment of the requirements of a problem. My strategy is to draw a gradual and relative distinction between what I call “framed” and “framing” inquiry. While the distinction is not explicitly present in Dewey’s works, it rests on Dewey’s functional distinction between existential and universal propositions. In a framed inquiry, the problem is covered by an existing conceptual framework, which is used to resolve the problem, without being revised. In a framing inquiry, the problem is underdetermined by existing conceptual frameworks, which are created, revised, or expanded. My general argument is that Dewey’s main contribution and controversial claims should be understood in the context of framing inquiry. In Chapter 1, I set the stage for the thesis. I paint the portrait of Dewey as the archetypal anti-realist; I present pragmatism as moving above this debate; and I present the specifically Deweyan brand of pragmatism. In Chapter 2, I introduce the distinction between framed and framing inquiry. In Chapter 3, I argue that realist notions of knowledge as representation, existence as independent facts, truth as correspondence can be cast in terms of framed inquiry, while most realists mistakenly interpret these notions as “unframed.” In the next three chapters, I defend and develop Dewey’s views for framing inquiry. In Chapter 4, I argue that framing inquiry should be construed as articulating rather than representing reality. In Chapter 5, I maintain that Dewey’s view avoids idealism. In Chapter 6, I defend the pragmatist theory of truth as a standard for framing inquiry, by contrast with representational standards.
