Ignosticism claims that knowledge regarding the reality of God is altogether unprofitable. This idea is directly contested by the mainstream teachings of monotheistic religions such as Judaism, Christianity, Islam, and Bahá'í Faith. It is the idea that every theological position assumes too much about the concept of God and other theological concepts; including (but not limited to) concepts of faith, spirituality, heaven, hell, afterlife, damnation, salvation, sin and the soul.
Ignosticism and theological noncognitivism are similar although whereas the ignostic says "every theological position assumes too much about the concept of God", the theological noncognitivist claims to have no concept whatever to label as "a concept of God", but the relationship of ignosticism to other nontheistic views is less clear. While Paul Kurtz finds the view to be compatible with both weak atheism and agnosticism, other philosophers consider ignosticism to be distinct.
