Personally, I think the very fact that babies (or dogs or ants or rocks) can be included in your definition of atheism indicates that there is something wrong with the definition.
Exactly. Sorry for butting in on your other response, but I just wanted to add support to your points.
It's become a definition that only labels a condition, and it's a condition of ignorance, i.e. not having a brain pattern or synapses that results in something. It's like having to declare the empty glass as "a-full" and make a deal out of it. I have the "a-full" glass, what do you have?
And how come Anthony Flew, considered one of the greater philosophers of atheism, write books about atheism if it's just a lack of something? How many books can a person write about the physics of the "a-full" glass? Flew gave argument to support atheism. He wrote about why and how and the pros and such, not a book about how to reduce belief to a "lack" in the brain. That's easy to do. Just get lobotomized and you're an atheist. No need to discuss. To Flew, atheism wasn't just lack of something, but rather a presence of arguments against religion. Atheism was something to him.
Problem 1
As you say above, the term isn't very meaningful. Why choose a definition that fails to impart meaning? Why purposefully make "atheism" a meaningless term? Wouldn't communication be better served by defining "atheism" in such a way that it imparts useful, meaningful information?
Agree. Why would people identify themselves under this label that only would qualify as a medical condition? It's not even a state of mind. It's the lack of a state of mind. It's a lack of view, which makes it strange that so many have a strong view about this. Why is there such a strong opinion about not having an opinion? I don't get it.
Problem 2
The "lack of belief" of atheists arguing in online debate forums is being equated with the "lack of belief" of babies.
This is borderline equivocation. The "lack of belief" of those who have come to a considered position regarding the existence of gods is quite different than that of a baby. It is not the same thing, and yet all get lumped together using this particular definition of "atheism". Thus we return to problem 1: this definition of atheism encourages conflation, which fosters misunderstanding, leading to the definition not being very useful as it fails to impart accurate information.
Yup. I actually think it's demeaning and derogatory to those who took their time and became atheists through a tough journey. Some atheists lost their faith and belief because they had an experience. They had reasons. They paid the price. Now, they identification is compared to ignorance. Atheists now are reduced to people who are ignorant about God/gods. Hence, the label doesn't fit those who spent the effort to become "atheists". A new label is needed for those who are atheists based on philosophical grounds.
