I'm not sure what you mean by "permeates science" but I do know which part of my post you're referring to. I was comparing two forms of faith. In one hand we have those who are willing to accept another persons faith without asking for a shred of empirical evidence in return. In the other hand we have those who are willing to accept another persons belief in something for as long as there is a good chance that empirical evidence can be found. In both cases we have two sets of people who are willing to accept another persons belief simply on faith.
I'm not denying that empiricism is valid in certain contexts.
What I am questioning is whether or to what degree post dated rain cheques are compatible with it.
"Boyant"?
Why did they build the LHC? It had to of taken a measurable degree of faith to strap Yuri Gagarin into a Vostok 3KA spacecraft on April 12, 1961. Not only was he the first man to journey into outer space but he also completed one full orbit around the planet. He had to believe that everyone in his space program did exactly what they were suppose to do and they all had to believe that what they were doing could be done.
It also takes an element of faith to accept the instruction manual that comes with a kiddie chemistry set.
It becomes something slightly different when you extrapolate that to all circumstances.
For instance its one thing to say "we can send a man into space"
It becomes something else to say "we can one day send a man anywhere into space"
Or similarly its one thing to say "light rays can be materially reduced to an analysis of its particles"
And its another to say "all things can be reduced to an analysis of its particles"
In both cases, the underlying faith of both claims is the superiority of the senses. IOW it presupposes that there is nothing "knowable" outside of applying one's senses.
This approach doesn't factor in the existence of higher sentience (such as god), an existence we wouldn't expect to be privy to with the blunt application of one's senses.
As a gross example, take the example of the president.
On an empirical level, all that is required to directly perceive him is to open about 15 doors at the whitehouse.
However since the president enjoys a higher social status, such an approach won't see one get past the first of his 100 secretaries. Rather, direct perception is achieved by being compliant with his needs, interests and concerns (which is how such persons as the secretary of defense and others get to directly perceive him).
Validating the existence of god occurs along similar lines.
