ABSTRACT
The language of interdisciplinarity is a philosophical language. For an efficient exchange of information and argumentation, some conditions for a common philosophical ethical language must be fullfilled: it is necessary to avoid some fallacies in ethically relevant arguments, and another aspect which may be a hindrance to a common philosophical ethical language is a hermeneutical one. The empirical fallacy or the fallacy ‘from is to ought’ consists in replacing questions of ethically right or wrong action with questions of empirically validated acceptance rates in a relevant population. In vitro fertilisation remains an offer of medical treatment with a burden, with risks – which, for example in the case of Intracytoplasmic sperm injection, will need further assessment – with a more or less low success rate and with more or less instrumentalisation of the early embryos.
