Is faith what it seems to be?
“Faith” always bothered me as a concept. I don’t mean faith based on experience, as “I have faith that my car will start” or “I have faith the pilot will land the plane safely”, but faith given as a reason for a belief (normally religious) in the absence of some actual evidence that the belief is true. It bothered me because it was apparent that there was nothing about faith that favored a true belief over a false one. “Faith” seemed to be whatever you felt like believing, and typically what people would like to be true has no particular connection to what is actually true.
In particular, it seemed unlikely that this could be an actual brain mechanism. Like our other organs, our brains seem to be extrememly well adapted for survival. Why would the brain have a mechanism which could generate beliefs that were independent of reality? This would detrimental to survival instead of helping it.
Perhaps the problem is that faith is not really a mechanism or reason for having a belief. Instead it is a reason people give when the real reason for having the belief is unacceptable for the purposes of argument. It is a rationalization. Like other rationalizations, the people giving it usually think it is the actual reason.
So if faith is a rationalization, what is the real reason for the belief? Wishful thinking is no doubt a part of it, but more often it is merely that we believe what others have told us. Someone in authority (a parent or a preacher) wants us to believe some doctrine. If we ask why we should believe their doctrine, they wouldn’t be very successful telling us to believe it “just because I say so”, or even because “everybody says so”. Instead they tell us to believe it through “faith”. They aren’t being insincere, because of course this is why they think they believe it themselves.
They also tell us that having faith is a virtue. This is a key to why “faith” as a concept is so successful. Good people have faith. Bad people don’t have faith. So rather than questioning whether what we have been fed is accurate, we are distracted by feeling good about ourselves because we have faith. We don’t even want to question what we have been told.
Faith has the additional virtue of being a conversation stopper. If somebody asks me why I believe what I do, I can say it’s because I have faith. I don’t have to provide any actual evidence. My discussion opponent has nothing to refute.
It is pretty obvious that what people believe on “faith” is tied closely to beliefs popular in their culture. People from India tend to have faith in the precepts of Hinduism, people in Saudi Arabia believe Islam, people from Ireland believe in Catholicism, and those from ancient Rome tended to believe in the Roman pantheon. This fits very well with faith being belief in what we are told.
So, is there some validity to believing things on faith, or is it just a rationalization for believing what we are told with some wishful thinking sprinkled in?
