As kind of introductory remark, let me state that I'm not academically-trained in philosophy, so my apologies if this comes up as a rather simple question.
I was reading Logique de Levinas by JF Lyotard, and I came upon, at the very beginning of the book, the following axiom which Lyotard coins as the enunciation clause, that is:
If "A is B", then "A is"
If we admit this axiom, which Lyotard states to be of dramatic importance in phenomenology, we're lead to aporia in some statements of Levinas, for instance:
Le tout autre est autre que tout ce qui est.
Loosely translated, "the Other is different from everything that is". But therefore, "Other is", which leads to a contradiction because it is different from anything that, precisely, is.
I'd like to know if there's some material there in the literature that discusses in a more pedagogical way this problem!
Thanks a lot!
