One who professes ignorance on the knowledge of whether or not any gods exist, or even what the term means. It is a play on the
words "ignorant" (to lack knowledge) and "gnostic," (knowledge pertaining to gods).
Ignosticism is sometimes compared to theological noncognitivism, and while one
may be both an ignostic and a theological noncognitivist, they
aren't mutually inclusive. It is also often compared to agnosticism, and nontheism in general. Most ignostics would be categorized as "
weak" or "negative" atheists.
