How it could be that we could think of God as a circle whose center is everywhere and circumference nowhere (to use the formula Borges is so fond of). A little bit about infinite sets. Seeing the Aleph (or another Aleph) in the Aleph. The relation of such sight to the Library of Babel: could there be an accurate (multi-volume) catalogue in the Library of Babel which listed every catalogue that didn't list itself? Leonardo on focal points and their relation to the Aleph. By occasion, mention of the Kabbalistic idea of the Aleph uttered only once in history, by God at Mt. Sinai.
