Agnosticism

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 unknown and (so far as can be judged) 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 difference between belief and knowledge, rather than about any specific claim or belief. In the popular sense, an agnostic is someone who neither believes nor disbelieves in the existence of a deity or deities, whereas a theist and an atheist believe and disbelieve, respectively. In the strict sense, however, agnosticism is the view that humanity does not currently possess the requisite knowledge and/or reason to provide sufficient rational grounds to justify the belief that deities either do or do not exist.
