I'm reading Levinas' book "From God who comes to the idea" (a Google translate from "De Dieu qui vient à l'idée"), and in the chapter "questions and answers" (a Q&A Levinas had with Dutch philosophers) appears a line "the other appears in a pantomathic way". I've looked up the definition of pantomath - basically a person who wants to know everything - and I just don't see the relation.
This line in the answer is related to the line in the question that stated that "when I read Finite and Infinity, it seems to me that the face of the other are as if they appear out of nowhere, what gives [Levinas'] philosophy a pantomathic characterism".
[note - all quotes are a vague translation by me, I hope you understand.]
