Full Idea
Roughly, Frege's picture of counting is this. When we count something, we determine what number belongs to a given concept.
Gist of Idea
Frege says counting is determining what number belongs to a given concept
Source
report of Gottlob Frege (Grundlagen der Arithmetik (Foundations) [1884], §54) by Kathrin Koslicki - Isolation and Non-arbitrary Division 2.1
Book Ref
-: 'Synthese' [-], p.405
A Reaction
If the concept were 'herd of sheep' that would need a context before there could be a fixed number. You can count until you get bored, like counting stars to get to sleep. 'Count off 20 sheep' has the number before the counting starts.
