Conceptualizing paradigms : on reading Kuhn’s history of the quantum

In this article, I discuss the criticisms raised against Thomas Kuhn’s Black-Body Theory. These criticisms concern two issues: how to understand Planck’s position with regards to the quantization of energy in 1901, and how to understand the book’s relation to The Structure of Scientific Revolutions. Both criticisms, I argue, concern the notion of a paradigm: the first concerns how Boltzmann acted as an exemplar for Planck, and the second whether the book provides a paradigm change. I will then argue that both criticisms presume a conceptualization of paradigms that does not align well with Kuhn’s conceptualization of it in both Structure and later work: they assume, more specifically, that sharing a paradigm presupposes sharing an interpretation of it, and that paradigm changes are essentially identical to gestalt switches. On the basis of this, I will then argue that the criticisms are misguided, that Kuhn’s position regarding Planck’s work is in fact quite close to the indetermination-view developed by some of his critics, and that the book fits Structure quite well. In conclusion, I will then reflect on how the narrative provided in Black-Body Theory connects with Kuhn’s views on the relation between history and philosophy of science.
