 This gives Peirce’s early account of signs a rather narrow scope; it is concerned primarily with the general and conventional signs of which our language and cognition consist. The reason for this narrow focus is simple: for Peirce, since symbols are “potentially general” and fall under the remit of general rules, they are a fit subject of study for his primary focus, logic. This early account, then, focuses mainly on general and conventional signs, those signs identified by Peirce as symbols. Icons and indices, although noted at this early stage, are considered of secondary philosophical importance. As we shall see later, this narrow focus is something that Peirce was later to revise.
