from Levinas's essay "Revelation in the Jewish Tradition.":
"...the totality of truth is made out of the contributions of a multiplicity of people: the uniquness of each act of listening carries the secret of the text; the voice of Revelation in precisely the inflection lent by each person's ear, is necessary for the truth of the Whole. The fact that God's living word can be heard in a variety of ways does not only mean that the Revelation adopts the measure of the people listening to it; rather, that measure becomes, itself, the measure of the Revelation. The multiplicity of people, each one of them indispensable, is necessary to produce all the dimensions of meaning; the multiplicity of meanings is due to the multiplicity of people."
Seems of self-evident and simple.
