You'll never get a definition where it will always be possible to judge whether every entity you examine belongs to that category.
Then it's impossible to reject all gods, or all beliefs in gods. Is nobody an atheist?
However, you can produce definitions that allow unambiguous classification in the majority of cases.
And that might work if you were defining atheism as "rejection of belief in
the majority of gods"... are you?
Here is one for "god":
"A supernatural being that has control over natural physical forces and that people worship."
Hmm. Okay... for the purposes of this discussion, that probably works. It might be overly broad - IMO, it probably includes some things like spirits, djinns, kami and the like that aren't normally considered gods - however, if you reject them while rejecting all gods, it's no skin off my nose.
Now... can you actually use this defintion as the basis for a rejection? Are you able to reject all things that meet this definition?
No. What I was saying was that you cannot know the meaning of "atheism" if you do not know the meaning of "god".
But you don't need to know the meaning of "atheism" to be an atheist. That requirement's not even in your overly restrictive definition.
I see no difference at all. A communist must know what communism is. An anti-communist must know what communism is.
So... in your view, someone who lived centuries ago, who espoused beliefs that we now recognize as being completely in keeping with communism, but never heard the word "communism" cannot be called a communist validly?
There are lots of words that are just like "theist" and "atheist". Your special treatment of words that rely on the concept of "god" is a form of special pleading, since you deny the relevance of your argument for other words.
Okay... can you give an example, then? Give me a word that, like your definition of communism, requires that the person make some express action or decision (e.g. rejection) for an entire category of thing (e.g. gods). Once you do, we'll see whether it has the same problems as your definition of atheism does.
You've completely lost me with this one.
Just as an atheist is someone who only believes in things that are not gods, an "a-geologist" is someone who only studies things that are not rocks.
Perhaps it would be better to stick with "-ism" examples. There is such a thing as antisemitism, and it is relevant to ask whether a given politician is an antisemite. If you tried to define antisemtism, you would find that it is not so easy. There are clear cases of it and borderline cases, just as there are for communists and atheists.
I don't see how this is relevant.
When we speak a language, we strive to use the same meanings for words as others--i.e. we assume that our meaning is "external" or acceptable to others. So we assume that our understanding is shared by others. The word "god" is no different from "door" in that respect and should not be treated as special. Again, I see you as engaging in special pleading in order not to be backed into the corner of admitting that you know enough about gods to believe that they do not exist. Doors, on the other hand, do exist, because we've seen them.
The issue isn't with the word "door" or "god"; it's with the issue "reject" and how it requires us to apply it to the thing in question. And if anything, I think it's you who's engaging in special pleading and me who's asking for consistency.
Rejection is a volitional act. If I say that I reject an entire category of things, then this means that I reject every single thing within that category. If the category is not properly defined to the extent that I can tell whether anything I don't reject falls within it, then I cannot truthfully say that I reject that category of thing.
I'm not sure what "other contexts" you mean here. I see no special problems that we do not encounter with other similar words.
I mean just what I touched on above: there are very few terms that require a person to perform an express act (e.g. rejection) on an entire category of thing (e.g. gods).
I thought about it more, and I came up with a couple... however, they seem to generally apply to cases where the category of thing is quite rigidly and narrowly defined, for instance: "vegetarian" (someone who refuses to eat all meats) or "teetotaller" (someone who refuses to drink alcohol). In these cases, it's easy enough to use the word, but these terms work
only because the distinction between "meat" and "not meat" (or "alcohol" and "not alcohol") is quite clear. This clarity is missing with the term "god".
Can you think of another term that's like your definition of atheist? One that involves someone performing an express act on an entire category of thing, but where that category of thing can't be rigidly defined? I can't think of any.
That doesn't even make any sense!
How exactly can I, reading your posts after you've written them, go back in time, climb inside your head and decide what
you meant to say?
Certaintly, we normally try to take the other person's understanding into account when we communicate, but ultimately,
my intended meaning is mine alone.
No, you were not using set theory properly to represent the babies state of mind. It is reasonable to believe that the baby has a set of beliefs about the world it rejects. All minds have that. What is unreasonable is to represent the set of things it doesn't have any concept for as being in that space. If there is a divide-by-zero error here, it is you who is committing the error. Move that empty set outside of the rejection space, and you have an accurate description of my definition and no division by zero.
Exactly what grounds do you have to "move the set"? It's an empty set; there's nothing to pin its location down anywhere.
Its location is undefined; you don't get to then define it as "anywhere but
this region".
That is a false dichotomy that is motivated by your desire to maintain your definition at all costs.
It's not a false dichotomy; it's a real dichotomy that comes from my understanding of the term "atheist". The mere fact that you have a different understanding of the term doesn't mean that I've committed a logical fallacy.
Your analogy with "conveyance" fails, because everyone knows what "car" and "conveyance" mean, and we can come up with conversational contexts where your sentence would sound natural. That is not true for persons who have no "god" concept. In any case, I've started a survey on usage just to see what folks in RF who hang out in this forum think.
Yes, and judging by how the survey's gone so far, it seems that the general consensus is going against you: as of right now, the majority of people who have responded to the survey have said that the term "atheist" does include babies.
Of course, it's not even a matter of a majority, is it? Even a sizeable minority would be enough to establish that it's a valid use of the term, right?
