Yes.


You seem to be blinded by your prejudices.

Before we can do that, we would have to ask: *what* things does
religion ask us to accept on faith?


It doesn't.


which causes you to misunderstand what John said. OF COURSE religion
asks us to accept certain things on faith. So does science.

Because we should accept nothing on faith.


Then you have no science. In fact, you have no LIFE.

To do so is to reject reason.


Not at all. Such a position is arrogant nonsense.

Faith is an epistemological system that can never reliably produce
accurate knowledge.


"Accurate knowledge." Hmm, that phrase seems to be tinged with private
interpretation. Science deals with models that allow prediction of
observable events. Models are maps, and we know that a map is not the
territory it purports to describe. "Accuracy" is a relative term, and
"knowledge" is what we gain by living and growing.

If faith is involved, then the search has already failed.


Then everything is vain. As John pointed out, science requires faith
in certain things, too: "Scientists accept on faith that the laws of
nature are consistent and intelligible."

This was certainly a problem for Saint Albert with the development of
quantum mechanics, which he himself started.

“If you are not completely confused by quantum mechanics,
you do not understand it.” -- John Wheeler

“It is safe to say that nobody understands quantum mechanics.”
-- Richard Feynman

We can predict a LOT of things with QM, so if "knowledge" means that,
then science gives us "accurate knowledge," but if "knowledge" means
"understanding" then science doesn't give us "accurate knowledge."

Some of the biggest questions in cosmology today are (1) What is dark
matter? (2) What is dark energy? (3) How can general relativity and
quantum mechanics be made compatible? (4) Did time start at the Big
Bang?

Quantum field theory is the most accurate map we have of the small,
but we have no idea how far "down" it reaches. Does it go to the
Planck level? What's below that? Is there a "below that"? String
theory says no. General Relativity is the most accurate map we have
of the large, but it doesn't tell us what dark matter and dark energy
are. Cosmologists take of faith that the FRWL metric accurately
describes the universe, but does it? Spacetime is a model, and we
don't know what the heck it is.

“spacetime is likely to be an approximate description of something quite
different.” – Steven Carlip
