Abstract

If the continental tradition from Nietzsche to Foucault has emphasized the critical and destabilizing implications of the genealogical method, analytical approaches have shown that it can also offer support to its own objects of investigation: behavioral norms, practices, concepts and so on. A genealogical account, for instance, is said to have a justificatory character when it identifies a necessary instrumental relationship between the concept or practice under consideration and human needs fundamental enough to be recognized as such by all. The question I want to address concerns the supposed justifying capabilities of this type of genealogical explanations. To what extent do they really modify – to use Wittgenstein's expression – the space of reasons? I here argue that their normative and evaluative scope is variable and that examining some borderline cases helps to demonstrate this. More specifically, I believe that in some cases the reasons offered through these explanations are reasons not so much to justify the use of certain concepts or practices, but reasons to excuse those who live by them.
