To be honest, certain words like "faith" or "grace" never made
any sense to me, even when I was going to church.
So for me, faith was a synonym for trust, as the words were used
interchangeably, and grace.. .well, that word still means
nothing to me.
So it could be a semantic error on my part.
I don't think modern physics requires faith/trust. The
correspondence level is very strong, although I always try to
make clear the distinction from the Map and the Territory.
It's when it goes into the esoteric that we end up with things
like parallel universes, string theory and such.
It's not that they might not be wrong, it's just these areas
seem more in the realm of religious faith rather than science.
