In this Conclusion, the author summarizes the main features of his theory of epistemic rationality and explains how his theory avoids commitment to any of the five presuppositions of the Proof Paradigm. He explains his new solution to the epistemological version of Berkeley’s puzzle. He recaps the real-world epistemological issues addressed by his theory. He concludes with some final thoughts, including a call to philosophers to reject both the presuppositions of the Proof Paradigm and the narrow scientism that characterizes so much of contemporary American philosophy. He urges us to replace that narrow scientism with a more expansive understanding of the human mind that can make sense of its “unreasonable effectiveness” in scientific and other inquiry.
