"ILLICH: I do this in order to make these students aware that virtuous behavior today might mean something different than at any previous time in history. I live with the refusal not only to say certain things but also to use certain words or to permit certain feelings to creep into my heart. I cannot allow myself to meditate on the atomic bomb without going under. Reflection on certain things we take for granted is, in my opinion, acceptance of self-destruction, of burning out your heart. And in addition to these easy-to-speak-about things, which cannot be discussed but only exorcised — such as genetic engineering, such as the atom bomb — there are other things, other realities which, once you accept that there might be intolerable realities, come very close to these destructive devices [...]
