Rabbi Dunner describes the extraordinary career of Rabbi Pinchas Menachem Mendel Hacohen Singer of Warsaw, a forgotten rabbi whose diligent leadership and patience with litigants and those seeking his counsel were faithfully recorded by his son many years after his death.

Using this amazing narrative record, and citing a Sefat Emet commentary on the verse in Shoftim (Deut. 16:20): “You must surely pursue justice,” Rabbi Dunner explains why the pursuit of justice and peace — even if at first glance ‘pursuit’ appears like an unseemly word to use — is a crucial aspect of one’s duty to these two fundamental aspects of the kind of society desired by God.
