What do you mean by faith Jim?
It seems that this reality within which we find ourselves is sufficiently complex that we must all adopt heuristics (rules of thumb, things that work in practice) at many different levels, to simplify things to a level that we can act reliably.
In this sense, we can be said to have faith in certain heuristics in certain contexts.
It seems that we need to be able to re-evaluate the utility of any heuristic if either the context changes, or we are confronted with sufficiently strong evidence of heuristic failure.
It is often difficult to recognise a change of context.
So in this heuristic sense, we all need faith at an operational level.
If one takes faith to mean the practice of ignoring evidence in favour of some pet belief, then it seems clear to me that is to be avoided, and it is something we are all prone to at many different levels.
