Blind Faith

"Blind faith is just as bad as being blind."
--The Doctor

Putting your faith into something that you know little to absolutely nothing about is just as bad as being blind. Blind faith is like crossing the street with your eyes closed; you never know where you are going.

I have noticed that quite a large fraction of misfortunes originate from not knowing where one has invested his trust. We always have a choice to put our faith in things, but we must never do it blindly.
