In a different recent thread, for clarity we made a distinction between unbelief (to mean lack of belief in x) and disbelief (to mean belief that x is false).
Good for you for remembering that. I also participated in that thread. I made the argument that whenever you have two distinct concepts and two different words to assign them, it makes sense to assign one meaning per word rather than let the two meanings blend and the two words be synonyms. The alternative is the kind of ambiguity we are seeing in this thread.
So I propose once again, as you have defined them here, let unbelief be the absence of belief, and disbelief be that the assertion is considered not merely unproven, but disproven (note how
un- and
dis- are used in these words - exactly analogously to when they are applied as prefixes to belief).
By this reckoning, disbelief is a subset of unbelief. Using other popular nomenclature, we would say that gnostic (strong) atheism is a subset of atheism, which includes both gnostic and agnostic atheists.
Also, I have no third distinct concept to assign to nonbelief, so I avoid the word. Adding it to these lists offered by other posters has only muddied those discussions, as with the post above this one. I liked the first two definitions, but found that the third one added nothing useful.
Some people seem to have a hard time wrapping their head around the notion that atheists don't necessarily think God doesn't exist, they simply aren't convinced he does.
Yes, it is a continual stumbling block for many people. Part of the blame, in my opinion, is due to definitions like this one from the Oxford English dictionary: "
atheism - disbelief or lack of belief in the existence of God or gods," or as we might say it, disbelief or unbelief in the existence of a god or gods.
I dislike that definition because adds to the confusion. Disbelief is not a necessary condition for atheism. Unbelief, with or without disbelief is, however. So why mention disbelief in the definition, unless it is being used synonymously with unbelief? It's like defining theist by singling out one set of theists in the definition,as with
Theist - any believer that Jesus is God, or belief in any other god or gods. Why single out the subset in a general definition?
in general everyday language, I agree that the terms are interchangeable.
Yes, unfortunately.
