Should we prevent non-therapeutic mutilation and extreme body modification?

In this paper, I discuss several arguments against non-therapeutic mutilation. Interventions into bodily integrity, which do not serve a therapeutic purpose and are not regarded as aesthetically acceptable by the majority, e.g. tongue splitting, branding and flesh stapling, are now practised, but, however, are still seen as a kind of 'aberration' that ought not to be allowed. I reject several arguments for a possible ban on these body modifications. I find the common pathologisation of body modifications, Kant's argument of duties to oneself and the objection from irrationality all wanting. In conclusion, I see no convincing support for prohibition of voluntary mutilations.
