Origin:
1150–1200; ME religioun (<>religion) <>religiōn- (s. of religiō) conscientiousness, piety, equiv. to relig(āre) to tie, fasten (re- re-+ ligāre to bind, tie; cf. ligament ) + -iōn- -ion; cf. rely

It's a pretty loaded word, isn't it? Brings up some deep, passionate feelings and beliefs. I have had many a debate simply because someone mentioned this one simple word in such a way that contradicted my meaning. But what is it really?

In a conversation about belief vs knowing (belief as in religion ; knowledge as in scientific proof and such), I came to the conclusion that belief fills the holes knowledge cannot. At least that is how it seems to work for me. If I don't know something or I find myself afraid of something, I turn to my religion for answers. It seems like that was common among at least a few others in the group (and please correct me if I'm wrong about that)

-I don't know how the world was created so I turn to the bible.

-I am afraid when I am alone in the dark so I turn to prayer.

-I worry about what comes after death so I turn to the church's teachings.

With this realization, I got to thinking. How can someone live without religion? I would surely go absolutely insane without it. ((Of course, I guess you could argue one could absolutely insane with it too...)) I really can't imagine my life without it. Does anyone have any thoughts on the topic? Or another definition of religion to ponder?
