On Religion

It does me no injury for my neighbor to say there are twenty gods or no God.

-Thomas Jefferson, third US president, architect and author(1743-1826)

This speaks to tolerance of others' beliefs. Of course, of your neighbour believes that his twenty gods oblige him to burn down his neighbour's house, then it certainly does injury.

However, Buddha had some interesting thoughts on belief formation which are very relevent, IMHO, to our time:

Do not believe in anything simply because you have heard it. Do not believe simply because it has been handed down over the generations. Do not believe in anything simply because it is rumored or spoken of by many. Do not believe in anything simply because it is written in Holy Scriptures. Do not believe in anything merely on the authority of teachers, elders, or wise men. Believe only after careful observation and analysis, when you find it agrees with reason and is conducive to the good and benefit of one and all. Then accept it and live up to it.

The Buddha on Belief, from the Kalama Sutra

There is no substitute for direct observation. Eyes Open! Mouth reserved! (I mean, not watching TV, but engaging the world).
