Agnosticism is the view that the truth values of certain claims—especially claims about the existence or non-existence of any deity, as well as other religious and metaphysical claims—are (currently) unknown. 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 difference between belief and knowledge, rather than about any specific claim or belief.
