My favorite part of this is:
   " Otherwise the love of nature is beginning to turn into a
   nature religion. And then, even if it does not lead us to the
   Dark Gods, it will lead us to a great deal of nonsense."

   This is very true. A form of pantheism is noticeable within many
   of the sciences, when they speak of abstract concepts as if they
   have ontological reality.*

   "The Universe is Mathematics" is one of those ideas gaining
   force.

   One that is harder to tease out the troubles with is:
   [1]https://en.wikipedia.org/wiki/Panentheism*as it _can_ be
   somewhat compatible with Orthodox Christian theology in some
   forms (but it is heretical because it's mono and not Triune -
   and the idea was resolved WAY back in the 1st Ecumenical Council
   if I remember right, , but in other forms, it's completely
   heretical with no redeeming qualities.
