I've noticed in my reading that most everyone who blogs on atheism or something related at some point gives some time to defining atheism. Since so many people feel the need to offer their idea, it must mean that there is no universally accepted meaning for the term. Atheist don't have their 28 fundamental beliefs. I've seen dozens of versions of an atheist Ten Commandments, but nothing central that you can point to and say 'you're an atheist so I know this about your beliefs. Certainly no label can adequately describe someone's world view. At any rate I got to thinking that it would be a beneficial exercise for me to take my turn at trying to express what being an atheist means to me.
There is a down side to this exercise though. I run the risk someone looking at this post and this is all they need to know about what I believe. However, my sincere desire is that a week from now I will have learned something or experienced something that will require me to refine my world view. I hope for my way of thinking to alway be flexible adapting to new information. If I'm ever static in my approach to interpreting the world I have failed. With that in mind I will try to describe what I believe. At least for today.
I call myself an atheist. I don't know if there is a god, but I don't think so. I suppose give some amount of evidence I could believe in a god. Given that I don't actively deny the existence of a god, sometimes I'm asked why I insist on labeling myself an atheist since the term is viewed so pejoratively (especially considering my background). I choose to use such an aggressive term because it does come the closest to what I believe. With the social circles that I run in, I don't want to misrepresent myself and have to deal with people trying to reconvert me. I'm past that. Proof of god's existences is not possible, but I have yet to come across any evidence that there might be a god. If there were evidence I would believe.
I am, however, definitely post-Christian. There is too much of the 'they just made it up' stuff associated with the Bible for me to ever go back to that. Not to mention all the dogma, institutionalism, bureaucracy and procedural garbage that is tied up with religion.
To sum up: I don't deny that god could exist, but I doubt it. Never-the-less, I will continue to refine my views to adapt to new learning.
