 Godfrey-Smith (1993) argues that systemic concepts of function do permit attributions of malfunction. He argues that a token component in a system is malfunctioning when it cannot play the role that lets other tokens of the same type feature in the explanation of the larger system. Davies (2003, 212) denies this. He says that functional types are defined in terms of what they can do and that if a component cannot carry out its normal contribution to the overall system then it ceases to be a member of a type. However, Davies’ objection appears to fail, at least in medical contexts, if we can identify components apart from their functional roles. Suppose we can identify biological components in terms of their anatomical position and relationships to other organs. If so, we can say that an organ in the position characteristic of its type remains a member of that type even though it has lost some capacity characteristic of that type, and hence is malfunctioning. Reasoning like this permits doctors to identify organs as normal or abnormal during autopsies, even though every system in a corpse no longer possesses its normal function in Davies’s sense.
