Rav Aharon Lichtenstein - Leaves of Faith 2 - Chapter 10

Nevertheless, given our present situation, I see no alternative to turning inward. The combination of rising assimilation and declining power mandates increased concern for specifically Jewish needs - spiritual, physical , and emotional. Despite the best humanitarian intention, we cannot escape the pressure of priority. "Many are thy people's needs, and their wit is limited," intones the piyyut and this aptly describes our current situation.Whether certain communal manifestations of of our collective generosity were in order a generation ago is perhaps debatable; that most can no longer be afforded is not. At the same time, we should make an educational effort to contain the insidious effects of creeping insularity. The notion, altogether too prevalent in some circles (albeit, perhaps not those likely to read this paper), that the concerns or even the suffering ofmere goyim are irrelevant to us cannot be countenanced.

Avraham Avinu and Moshe Rabbenu, at any rate, thought otherwise.
