After reading the classics Robert Putnam's Bowling Alone and Sam Harris' The End of Faith, I wonder if people identify their religious beliefs not on scientific reasoning but community connections. Our increased individualistic society is only made worse by internet companies that keep us in what Eli Pariser calls a Filter Bubble. Yet finding common cause on the internet can create and support shared common values, of the religious or areligious type.
Community is key to believing. We are influenced by those around us and the sites we visit. Diversity is important not only to 'keep things interesting,' but also to ensure we do not become stagnant in our beliefs. If we want to share our beliefs, be they secular or spiritual, it is better to do so through relationship rather than pure reason.
