Abstract

I propose a rational reconstruction of the early quantum theory (1900-1913) in terms of the ideas presented by Ernst Cassirer. Specifically, I propose to reconsider the early quantum theory through the lens of the method of conceptual functionalization that Ernst Cassirer laid down in his Substance and Function (1910) and he later refined in Determinism and Indeterminism in Modern Physics (1937). Following Cassirer’s functional interpretation of natural sciences, it is my primary concern to reconsider the conceptual evolution of Planck’s quantum of action from 1900 to 1913. In this regard, I shall emphasize the importance of the quantum of action (Planck’s constant) in the architectonic structure of the early quantum theory, in the role of an element of fundamental continuity between the first quantum theory and the formulation by Niels Bohr of the first atomic theory.

Author Biography

Roberto Angeloni, Université Paris 7 – Denis Diderot, France

Roberto Angeloni is a Marie Curie fellow at the University of Paris Diderot, France, after being awarded the
prestigious Marie Skłodowska Curie fellowship. Since his PhD’s completion (University of Cagliari, Italy, 2011),
Angeloni has organized several international workshops and seminars; he has participated in numerous
international conferences, and he has published two books and several papers in the field of the history and
philosophy of science and history of physics. Angeloni’s research interests range over a great variety of themes: from the foundations of quantum theory to the history of contemporary philosophy, with particular regard to the neo–Kantian School of Marburg and the history of the philosophy of science in the twentieth century.
