Agnosticism is the view that the truth value of certain claims—especially claims about the existence of any deity, but also other religious and metaphysical claims—is unknown or unknowable. Agnosticism can be defined in various ways, and is sometimes used to indicate doubt or a skeptical approach to questions. In some senses, agnosticism is a stance about the differences between belief and knowledge, rather than about any specific claim or belief. As such, the term agnostic does not necessarily signal a particular view about religion or a deity, as some agnostics also identify as theists or atheists.
