yekke2 –
I was talking about the ???? of the ????”?.
Even so, I would argue that there is no difference between the mechanism of rov and the mechanism of bitul. Both are dinim, and both are based on the concept that the probability is in the majority. (And while according to the Rosh there is the added din by bitul that the minority changes its din to be like the majority, that is a secondary halacha which takes place precisely because the classic din of rov took effect.)
Truth is when I learned Kesubos in yeshiva I had a whole bunch of ideas about sfeikos and rov too. But when I relearned it in the context of Yoreh Deah and after I’d become acquainted with the mehalech of being ???? ?????? ????? ??????, I laughed at my earlier self. If you don’t already, do yourself a favor and learn lots of bekius (Gemara+Rashi+the Tosafos that look interesting). It’ll do you a wealth of good.
Anyway, forgive me for getting on my soapbox and all. It’s not personal, this is just kind of my “thing.”
