What were Argentine writer Jorge Luis Borges’ religious beliefs?
Self-identified agnostic.
Didn’t he write/say that to him heaven would be an infinite library? Very Borgesian.
Well, hopefully not a Library of Babel. You spend five million years finding a copy of Hamlet only to discover the final act is replaced with the letter a repeated over and over. Sounds like hell to me.
I’m sure God would have bothered to install a computer search database 
Luckily somewhere in that library there is a directory of that library. In fact there, are many directories, one of them being correct, many of them differeing from the correct one by just minor spelling errors, and many others being utterly wrong. Now that I come to think of it, that wouldn’t be much help.
That wouldn’t help: read the first paragraph here.
