Okay, so let me see if I understand you correctly. Now, there's the proposition ''/at least one God exists.'' It could be true or false. As for my belief about its truth value, we could represent it with any number from -1 to 1; -1 means I believe with certainty it's false, 1 means I believe with certainty that it's true, 0 means I'm completely uncertain and I don't lean either way. Then, there's everything in between. What you're saying is that an agnostic is someone who is 0 or very close to 0. An agnostic atheist is someone with a negative value who is still very close to 0, and an agnostic theist is someone who is positive but close to 0. Do I understand you correctly?
