Yosef Hayim Yerushalmi - Zakhor (p. 44).
For whatever memories were unleashed by the commemorative rituals and liturgies were surely not a matter of intellection, but of evocation and identification.... This can perhaps be perceived most clearly in that quintessential exercise in Jewish group memory which is the Passover Seder. Here, in the course of a meal around the family table, ritual, liturgy, and even culinary elements are orchestrated to transmit a vital past from one generation to the next. The entire Seder is a symbolic enactment of an historical scenario whose three great acts structure the Haggadah that is read aloud: slavery—deliverance—ultimate redemption. Significantly, one of the first ritual acts to be performed is the lifting up of a piece of unleavened bread (matzah) before those assembled, with the declaration: Ha lahma ‘anya—“This is the bread of affliction which our forefathers ate in the Land of Egypt” Both the language and the gesture are geared to spur, not so much a leap of memory as a fusion of past and present. Memory here is no longer recollection, which still preserves a sense of distance, but reactualization...
...nowhere is the notion brought forth more vigorously than in a Talmudic dictum central to the Passover Haggadah itself. “In each and every generation let each person regard himself as though he had emerged from Egypt.”
Pesach Jews V. Purim Jews: The Agony of our Dilemma

Jewish history speaks to our generation in the voice of two biblical commands to remember. The first voice commands us to remember that we were strangers in the land of Eypt, and the message of that command is: Don’t be brutal. The second voice commands us to remember how the tribe of Amalek attacked us without provocation while we were wandering in the desert, and the message of that command is: Don’t be naive.
The first command is the voice of Passover, of liberation; the second is the voice of Purim, commemorating our victory over the genocidal threat of Haman, a descendant of Amalek. “Passover Jews” are motivated by empathy with the oppressed; “Purim Jews” are motivated by alertness to threat. Both are essential; one without the other creates an unbalanced Jewish personality, a distortion of Jewish history and values.
