In the foreword to his book, Planetary Service, Eugen Rosenstock-Huessy observed:
Every religion is characterized solely by its type of sacrifice. There are all sorts of human sacrifices, as well as sacrifices of animals, of money, of time, and of sanity. And the only religion which would be appropriate for all of mankind would require that we sacrifice part of ourselves. This is therefore the only binding religion which has a future. A religion demanding human sacrifices a la Hitler, must disappear.
