 Talk of biological functions does often seem to have at least a teleological flavor. For example, to say that it is the function of the heart to pump blood can seem equivalent to saying that hearts are for pumping blood, or that hearts are there in order to pump blood (see esp. Wright 1973). There is also the closely related concept of an artifact’s function that appears to be purposive: for example, when we say that moving the cursor is the function of the computer’s trackpad, we might mean that this is what the trackpad was designed to do or was intended to do by the computer’s designer or user. Of course, if a teleological theory of mental content is to be a non-circular theory of original intentionality, the functions to which it appeals, as grounding original intentionality, cannot in turn depend on other intentional phenomena. (Some, but not all, prefer to use the term “teleonomic” in that case.)
