quod erat demonstrandum

"which was the thing to be proved"

Two more phrases I've been saving:

“Les nerfs—voilá tout l’homme!” French doctor Pierre Cabanis, 200 yrs ago;
"The nerves: that’s all there is to man" (I think the translation is a bit weak though; I prefer something like "Nerves - voilá; that's all man is!").


“From death, from the fear of death arises all knowledge of the All.”
Franz Rosenzweig - first line of "The Star of Redemption". (apparently; I'm not yet sophisticated enough to have actually read it.) I assume it was in fact in German, but we've covered enough languages for now.
