<div dir="ltr"><<As I understand him, the CI (YD, Hilkhos Tereifos 5:3; Yevamos 57:3)<br>
is saying there was an exact time of transition from the era of Torah<br>
to the era of Geulah. That's different than saying that time was the<br>
year 4000 AM on the nose. Just as the year 2000 AM (in a chronology the<br>
CI would accept) doesn't mark any notable event I'm aware of -- Migdal<br>
Bavel was 1996 AM, Noach dies in 2006, Beris Bein haBesarim is 2018.>><br>
<br>
I just have trouble with the concept that R Chiya could disagree with Rebbe<br>
one day but not the following day.258)<br>
<br>
Reminds of the discussion about the halachic dateline where most poskim say<br>
we don't take 90 degrees (according to that shita) from Jerusalem because that would<br>
imply that two halves of a house are in different days. Rather we extend the time<br>
zone to the end of the land mass.<br>
<br>
On a slightly different matter I looked again Hilchatit Refuit by Dr.<br>
Steinberg (vol 2 p258)<br>
He brings the gemara Bechorot44b and Yevamot 75b that the male has 2 parts<br>
for semen and urine while modern anatomy claims they combine. CI (Even Haezer 15:7) claims<br>
that nishtane hateva while in Peer Hador vol 4 p142 it seems that CI held this<br>
was a physical change and not just a halachic rationalization.<br>
<br>
Note that in other cases various rishonim already use nishtane hateva to<br>
change halachot from the days of chazal<br>
