Summary

In this seminar, Robert Brandom introduces Frege’s Grundlagen der Arithmetik (1884), focusing on the first 60 sections. He argues that Frege’s primary interest is not numbers per se, but rather the introduction of new meta-concepts of object and concept. Brandom highlights Frege’s motivation: numbers are paradigmatic objects because we lack causal interactions with them, forcing a purely semantic understanding of objecthood. He discusses Frege’s early view from the Begriffsschrift, where conceptual content is defined inferentially via substitution in implications. Brandom contrasts this with a truth-based model, noting a tension that Frege later resolved. He then examines Frege’s question ‘How many?’ and his claim that numbers are answers to this question, leading to the idea that objects are what can be counted. Brandom introduces the distinction between object naturalism and subject naturalism (following Huw Price), linking the latter to Wittgenstein’s approach: understanding the practice of counting suffices to understand numbers. He critiques the view that numbers are properties of objects, showing why ‘one’ cannot be a property. Finally, he discusses Frege’s rejection of the notion of ‘unit’ as combining identity and difference paradoxically, and hints at Frege’s positive account to come.
