I've updated a chart that maps out the basic relationships between atheism, agnosticism, and theism, and their respective statements or beliefs. Atheism is sub-categorized into gnostic and agnostic forms, and further sub-categorized into strong, moderate, and weak forms, along with agnosticism and theism, which allows for a 9 point scale of belief from atheism to theism.
No chart will ever satisfy everyone though. While atheism and theism are generally about belief, agnosticism is about knowledge. But gnostic atheism and theism both make claims to knowledge, and that's why they both come in gnostic and agnostic forms.
This chart also doesn't include other isms like pantheism and deism, so believers in those views might be disappointed in this scale. It isn't supposed to cover every possible god option, just the scale between atheism and theism.
So where do you fall in this category? Feel free to link or share this chart.
