Strong agnosticism (also called hard agnosticism, closed agnosticism, strict agnosticism)—the view that the question of the existence of deities is unknowable by nature or that human beings are ill-equipped to judge the evidence.
Weak agnosticism (also called soft agnosticism, open agnosticism, empirical agnosticism)—the view that the existence or nonexistence of God or gods is currently unknown but isn't necessarily unknowable, therefore one will withhold judgement until more evidence is available.
Apatheism—the view that the whole question of God's existence or nonexistence is beneath consideration or concern.
Apathetic agnosticism—the view that the whole question of God's existence or nonexistence cannot yet be properly answered, and therefore one should free oneself from a fruitless search.
Ignosticism—the view that the concept of God as a being is meaningless because it has no verifiable consequences, therefore it cannot be usefully discussed as having existence or nonexistence. See scientific method.
Model agnosticism—the view that philosophical and metaphysical questions are not ultimately verifiable but that a model of malleable assumption should be built upon rational thought. Note that this branch of agnosticism differs from others in that it does not focus upon the question of a deity's existence.
Agnostic theism—the view of those who do not claim to know God's existence, but still believe in his existence. (See Knowledge Vs Beliefs) Whether this is truly agnosticism is disputed. It might also imply the belief that there is something resembling god (or gods,) but a doubt of their exact nature or validity of claim.
Agnostic spiritualism—the view that there may or may not be a god (or gods,) while maintaining a general personal belief in a spiritual aspect of reality, particularly without distinct religious basis, or adherence to any doctrine.
Agnostic atheism—the view that God may or may not exist, but that his non-existence is more likely. Some agnostic atheists would at least partially base their beliefs on Occam's Razor.
