- I don't believe in X -> I believe ~X.
- I don't believe in X -> I lack the belief X.
I hold (1), you hold (2). That is our difference. Of course we are talking about colloquial conversation, not some sort of partitioned-off logical analysis. I gave
an argument in the form of common phrases in favor of my position, and you gave no argument for your own. To be clear:
- I don't believe in unicorns -> I believe unicorns do not exist.
- I don't believe in second chances -> I believe second chances do not exist.
- I don't believe it will rain tomorrow -> I believe it will not rain tomorrow.
- I don't believe the Giants will win the Superbowl -> I believe the Giants will not win the Superbowl.
I admit that your case is not implausible at a first glace, but once the matter is analyzed more deeply it becomes clear that your argument is based on a misuse of language and an incapacity to acknowledge the actual meaning of words and phrases in English. You desire language to work like (2)
because this would be convenient for the type of "atheism" you wish to propose. But language isn't determined by convenience. In order to know what a word or phrase means we must look at usage and follow the evidence where it leads. We must accept the truth passively rather than actively imposing our personal will. In the colloquial and dictionary world, (1) is true and (2) is false. Therefore even the small percentage of definitions to which your argument applies do not favor your position.
