You Don't Choose What To Believe In

[haxxiy]

You are perceiving people as if they were static entities... just as personalities can slowly change with time, so does their beliefs.

I don't think anyone does believe that simply reading the bible, or say, understanding M theory, or a clever philosophical argument for one side or another, can suddenly make someone a christian or an atheist. We even have a special word for those rare cases where it supposedly happens: epiphany.
