Abstract

As is well known, Frege stated that the expression ‘the concept horse’ refers to an object and not to a concept. In this article we firstly show how there are some hints of this paradox in texts prior to 1891. Secondly we review some arguments given in the literature to hold that with ‘the concept horse’ Frege referred to the extension of the mentioned concept. Finally, we argue that, even if the concept horse is such an extension, we still know very little about its nature, given the fragmentary way in which Frege introduces the extensions of concepts in Grundgesetze and in previous essays.
