The Discovery-Justification Distinction and the New Historiography of Science: On Thomas Kuhn’s Thalheimer Lectures

Abstract

I will examine the first of Thomas Kuhn’s Thalheimer Lectures delivered in 1984, with the purpose of establishing a connection between Kuhn’s historiographical thought and his criticism of the traditional distinction between the context of discovery and the context of justification, or, as I call it, the DJ distinction. In order to do this, I will start by exploring the Kuhnian view of the so-called static approach in philosophy of science, taking as my main reference the work of Bacon, Descartes, and foundationalist epistemology. I will continue by examining the relationship between Kuhnian historiography and the DJ distinction, comparing the first Thalheimer Lecture with other texts published by Kuhn. Finally, I will assert that Kuhn’s rejection of the DJ distinction is the result of adopting a historiographical matrix whose philosophical consequences are irreconcilable with the static approach in history and philosophy of science, for which the DJ distinction is essential.
