Here's a follow-up to my "Atheism isn't a belief. It is a lack of belief." That post had quotes from James Lindsay's second book.
The passages below are from Lindsay's first book, God Doesn't, We Do. Once again, he persuasively challenges the false assumption that theism, believing in God, and atheism, not believing in God, are somehow both belief systems.
Doesn't make sense. Read on to see why.
Another common misconception among believers is that infidels, atheists in particular, subscribe to a religious view that is called Atheism. This is incorrect, generally speaking.
We might be able to call (capitalized) Atheism a quasi-religion in that it lacks a Supreme Being -- indeed it categorically denies the existence of any such thing. Quasi-religions of varying sorts could be built beginning with a categorical denial of deities, for example by equipping that denial with ideas from Buddhism, Taoism, the Jedi of Star Wars, or many New Age belief systems.
States could also create them. Maoism, particularly, could easily have become such a religion. Importantly, though, this position is rarely held. This is because it is the difficulty with claiming an unknowable philosophical position with certainty that pushes people away from theistic belief.
While Atheism is an ideological position without a completely firm philosophical basis, (lowercase) atheism is just the denial or rejection of theism, the belief in a god or gods, and its philosophical, moral, and intellectual base is substantial.
Lowercase atheism is not a religion or even an ideology.
...Since atheism is a position free of dogma, those that have denied religion are free to think about the world how they will, often earning them the title of freethinker. Without religion, many turn to or seek a scientific understanding of the world, frankly because it works quite successfully, though excitingly incompletely, at explaining what is.
Even in this worthwhile endeavor, though, there is no requirement. Atheism, quite opposite religion, and in some ways to its detriment (politically, for example) requires and thus has no unifying creed, doctrine, dogma, or agenda.
It is just an unfortunate title for people that do not believe in supernatural gods, and it is a title that should be every bit as unnecessary as a-Santa-ist or a-faerie-ist.
