I do not know greek language, but I have to determine the exact meaning of two terms. The terms are "dsa" and "dei". One could find them in the following (Aristotle, "Topica",VII):
(Sorry for writing without accents)
"... dsa gar qateron categoreitai, xai qateron categoreisqai dei".
The meaning is something like "for all that is predicated of the one should be also predicated of the other" (Aristotle is giving a definition for "sameness").
