 The key constructivist contention, as seen in the remark by Amundson quoted above, is that there is no natural, objectively definable set of human malfunctions that cause disease. Rather, constructivists assert that to call a condition a disease is to make a judgment that someone in that condition is undergoing a specific kind of harm that we explain in terms of bodily processes. But the bodily processes are not objectively malfunctioning; rather, they are merely judged by us to be unusual or abnormal because they depart from some shared, usually culturally specific, conception of human nature. The crucial difference between the positions then is that for naturalists, diseases are objectively malfunctioning biological processes that cause harms. For constructivists, diseases are harms that we blame on some biological process because it causes the harm, not because it is objectively dysfunctional.
