While Will and Kate push this day over the top, I figured it would be a nice foil to go back to basics. This is what being Atheist means to me.
I don't believe there are any supernatural gods. I don't know that there aren't any supernatural gods but my commitment to applying logic to what I believe leads me to a conclusion that there is a much stronger probability of the inexistence of gods than the existence of gods. I am not afraid of being wrong and hence don't feel compelled to close my mind to the possibility (albeit incredibly unlikely) that a god exists. What makes me, and I suggest all non-theists, different than believers is that the foundation of my non-belief is based on that which is objectively probable, while their belief is based on a faith with no objective probability. This is not a judgement statement, just an indisputable observation.
Simple as that. My deeper value set and how I choose to treat the world and its creatures doesn't come from my lack of theism just like a theist's approach to life doesn't stem from his or her non-belief in the thousands of gods outside of their chosen faith. How shallow would that be? My chosen life approach comes from an innate desire to treat my world with deserved respect. An inherent feeling that it is just "right" to do good. Call it humanism if you must label it.
That's it. If this sounds like you, embrace it openly.
Enjoy the wedding and congrats William and Kate. You seem lovely.
