 These arguments all have their weakness when it comes to their ability to justify belief in other animal minds, just as the humancentric versions do when it comes to other human minds. Even when used in conjunction with one another, there is room for doubt when it comes to other minds. However, in the case of humans, it is deemed a mental illness to worry that the others around you are actually minded. The weakness of these arguments suggests that when we are doing science and trying to determine the causes of behavior, we are engaged in one project, but when we are considering the traditional problem of other minds when it comes to other animals, we are engaged in a different kind of project, one of relating to others.
