Abstract
To what extent is conceptual analysis under strict semantic control? In an effort to show that conceptual structure transcends the linguistic dimension proper, the tensions within, and between, several current treatments of the concept red are revealed and explored. It is argued that certain extra-semantic factors — factors, broadly speaking, which concern the manner in which a concept applier interacts with the world as an extralinguistic agent - provide a backdrop against which conceptual analysis guided by language in a strict sense must be deepened and tested.
