anathematica

so thinking about neal stephenson's last tome, Anathem, it is a paeon to
science - the point of the story (spoiler alert:) Is that
the best people to communicate with aliens are scientists
because the "language" of science is (quite literally) universal (actually, it is meta-universal) so even if aliens show up from (several) parallel Universes
then we (scientists, or "avout" steeped in "theorics") can communicate with them - indeed, the aliens have a helpful clue (much as voyager does) which is they have a diagram of the geometric proof of Pythagoras (of coruse, neither they nor the folks
on the planet (arbre) call it Pythagoras) on the outside of their "ship"

one discussion about meta-theory centers on whether the metaverse is ordered (DAG) or random, and whether there is some "higher" versus "lower" plane; another discussion is about Hemn (quantum state) spaces....another is about cross breeding plants to grow a simulation of a part of history....still another is about time

most religions are given fairly short shrift in the book (though not all) and of course there are (as in snow crash) some cool dudes who do marshal arts quite well...
