The notion of blasphemy is both in the field of linguistics - for blasphemy is an act of language - and theology - for blasphemy is an outrage to God. As is well known, the competence that I possess only affects linguistics. It is therefore in linguistics that I will pose one of the linguistic problems posed by blasphemy: that of the relations between blasphemy and autonomy. The result is to be foreseen: for lack of competence in theology, I will at most be able to pose this problem, without being able to solve it. I am not really sure that he can receive a clear solution. Before turning to this problem, however, I think it is useful to briefly describe the state of blasphemy today.
