The Emergence of Logical Pluralism: A Closer Look at the Philosophy of Hans Hahn
(History of Philosophy, English)

Outlines of the history or philosophy of logical empiricism mention Hans Hahn in passing, if at all. He is usually characterized as a typical proponent of the Vienna Circle, embracing both empiricism and modern logic, defending logicism, and rejecting synthetic judgements a priori.

However, by considering archival material and the specific audience of his few philosophical writings, this paper argues that a closer look at Hahn's philosophy reveals hitherto underappreciated peculiarities.

We argue that (1) by adapting Russell's logicism and Wittgenstein's nominalism, Hahn develops his own specific variant of logicism, (2) Hahn consistently defends a principle of tolerance and logical pluralism prior to Carnap and Menger, and (3) contrary to first impressions, Hahn's logical pluralism is compatible with his endorsement of Occam's Razor.
