Not all faith is blind. Some faith is justified as its built into the system of knowledge.

Think about deductive truths, which are basically all tautologies such as 2=2. They're all knowable a priori. Are they really held to falsifiability though?

1+1=2. How could conceivably prove that wrong? Bearing in mind that if you would have to do so in a way that didn't demonstrate misunderstanding about the qualities of 1, 2, addition, or identity, because you'd simply be talking about something else.

Scientific zealots often think that the entire paradigm of thought needs to be rehashed scientifically, but in thinking to do so they ignore certain foundational assumptions that science operates by, the inner workings of science which are invisible to the process itself. Science is a powerful tool for progress but its application isn't total. Theories can be extended beyond their context with disasterous consequences (think social darwinism if you like). Science all too often fails to understand itself as metaphorically representative of reality.

And I fail to understand how some people think their particular representative mythologies are better than other peoples.
