Here's an old question: How can you be religious when there is zero evidence to support the idea of Gods and no reason to think such a thing exists? Is it not foolish to act so illogically?
And here's one perspective.
I live with depression. Depression is very clever at erasing evidence. You can list all sorts of reasons for being glad and enjoying life, and depression can knock down every last one of them. When depression is masking your brain, it truly seems as though there is no reason at all to keep going.
But you keep going nonetheless, because you have some hazy idea that there's something beyond what the evidence suggests. Some days faith in that idea is the only thing that keeps you from giving up and swigging lethal quantities of codeine and whisky.
Most people around one agree that giving up is a bad idea. They encourage you to keep it up with the blind faith, against all perceptible evidence and rational analysis. Thus, apparently, sometimes blind faith, against the evidence and contrary to logic, is not wholly a bad thing.
I live much of my life on the basis that there is a state of being better than the one I presently perceive, even though the depression in my brain makes me unable to reason out how this could be. Even though all the available evidence suggests that such a belief is entirely unfounded, I choose to believe it, and no-one would say me nay.
As a religious person, I also live much of my life on the basis that there is a state of being beyond my present perception, even though reason and observation cannot support it.
Just as sometimes the depression lifts and life can be enjoyed, sometimes life's perspective widens and transcendence can be experienced. Both of these add value to my life.
The frames of mind which lead to each are precisely similar. One does not require any more suspension of disbelief than the other. It is not about living one's life entirely by rational scientific principles and then having a whole different set of rules for religion that require reason to be abandoned; from this perspective, it is simply about how much one concedes may be beyond the evidence. If it is not unreasonable to live with irrational faith concerning the one, it does not seem unreasonable to live with irrational faith concerning the other.
