Reply To: opinion about OTD

YYA> De facto Yitchok Avinu saw plenty of the surrounding population in the home of Avraham, and how Avraham interacted with them.

I think R Hirsh means that Yitzhak needed to observe people who think differently, not just those who were already talmidei Avraham.

If you want to put it in statistical terms, if Yitzhak’s role was to expand on Avraham’s teaching [although this contradicts a popular idea that Yitzhak was mostly following what Avraham did, like wells …] – then observing talmidei Avraham is not sufficient – he needs to observe those who were not yet affected.
