1) The big answers about life require struggle
With atheism, you don't get any prepackaged answers. Science has become the default explanation, but unlike theists, those answers had to be worked for, instead of just having them handed down from on high.
2) We are intricately part of the natural world
Voisey quotes Chuck Lunney:
Rather than being created apart and unique from the rest of the living biosphere, accepting the fact that humans are part of and intimately connected to the universe makes me care intensely about every little thing that exists.
3) A love for critical thought and skepticism
Another advantage [of the atheist] mindset is that it avoids hasty and irrational decisions. Every time I've heard about people being taken in by the silly Nigerian Email scam, it's always someone taking a "something for nothing" offer on blind faith. . . This is not to say that atheists are immune to such scams, but having a mindset that requires actually holding answers up to some sort of scrutiny greatly decreases the chances of getting taken in by frauds.
Another one of the things I'm quite happy about is that I have a general optimistic view of humanity. Unlike religion, which tells us that humans are all awful sinners and deserve eternal damnation unless they accept the particular deity of choice, atheism carries no such inherent emotional baggage. We're free to actually make informed decisions on one another.
5) Claiming ownership of one’s own life
Lastly, I'm glad for my time. Not just that I get to sleep in on Sunday mornings, but that I get to actually live my life without absurd notions about what I have to do or not do to to (sic) ensure eternal life. It's freeing to know that my time is my own and that, when I do give it, it's because I do so knowing I care about friends and humanity, and not because I'm trying to earn karma points for the afterlife.
These are positive values, and I subscribe to these, but I think some atheists mistakenly believe that these values are unique to atheism. I know they are not, as I personally know theists who subscribe to many of these as well. However, I wonder if intellectual atheism at least encourages these values.
