 An interesting feature of Peirce’s early account is that he is keen to associate signs with cognition. In particular, Peirce claims that all thought is in signs (W2. 213). We can see this from Peirce’s early idea that every interpretant is itself a further sign of the signified object. Since interpretants are the interpreting thoughts we have of signifying relations, and these interpreting thoughts are themselves signs, it seems to be a straight-forward consequence that all thoughts are signs, or as Peirce calls them “thought-signs”. One interesting consequence of this is that in the early account, Peirce is quick to dismiss the importance and relevance of icons and indices.
