Foucault and ascetic language

["D.H.Moldenhagen" <Dag.H.Moldenhagen@xxxxxxxxx>]

 A friend of mine told me that there is some descriptions of theological or
scientific language as "ascetic language" in Foucaults history of sexuality.
I have searched through the works but has not succeeded in finding it. Does
anyone know about the reference?
