Discussing the mind, we face a clear asymmetry: While the brain can be scientifically observed, the mind cannot. However, in order to reproduce something, we need to observe it. The claim according to which the artificial reproduction of some mental activities would be helpful in understanding the mind is weak in principle. For instance, what any school of A.I. tries to reproduce is not the mind but a model of it coming from a specific psychological or ontological paradigm that assumes the existence of the mind as something given. Therefore, the "eradication" of the mind from the brain evolution and activity adds a further degree of arbitrariness to the unavoidable bias and transfiguration that characterizes every attempt to reproduce natural objects, that is, to design naturoids.
