Which interdisciplinary model does neuroethics require?

In this paper, I analyze two paradigmatic contemporary ways of understanding the relation between the disciplines involved in neuroethics. In particular, I criticize the form interdisciplinarity takes in these two models. It is pointed out that, according to one of these, the philosophical reflection does not allow neuroscientific evidence to influence in any significant way the theoretical presupositions of that reflection. According to the second model, on the contrary, the role of the empirical component, essential to neuroethics, rather blocks the ethical and philosophical reflection.
