Scientism is to science as Christianism is to Christianity, and as any other fundamentalism is to its respective host faith.

Faiths are not doctrines, nor are they moral laws, nor are they sets of rituals — nor are they all three. These explicit things are important expressions of faith, but faiths themselves are like people — we know them indirectly by what they do, by how they affect us, and most of all by how they shock us. The minute we reduce the soul of a person or a faith to the explicit forms we can pack nicely into the confines of a mind we repeat the original sin of treating knowledge as something we grasp with comprehending fingers instead of as something we inhabit, like an environing garden. 

We know science by how it works, how it responds to challenges and shocks, by what happens to us when we work together by its faith that we can come to [always-tentative!] agreements — if we respect one another enough to produce and accept demonstrations showing why we ought to believe whatever we believe. 

Amen?
