Parrhesia appears in Midrashic literature as a condition for the transmission of Torah. Connoting open and public communication, "parrhesia" appears in combination with the term ("dimus", short for "dimosia"), translated "coram publica", in the public eye, i.e. open to the public. As a mode of communication it is repeatedly described in terms analogous to a commons. "Parrhesia" is closely associated with an ownerless wilderness of primary mytho-geographic import, the "Midbar Sinai" in which the Torah was initially received. The dissemination of Torah thus depends on its teachers cultivating a nature that is as open, ownerless, and sharing as that wilderness. The term is important to advocates of Open Source Judaism. Here is the text from the Mekhilta where the term "dimus parrhesia" appears (see bolded text).
