Possibilianism is a philosophy which rejects both the idiosyncratic claims of traditional theism and the positions of certainty in atheism in favor of a middle, exploratory ground. The term was first defined by neuroscientist David Eagleman in relation to his book of fiction Sum. Asked whether he was an atheist or a religious person on a National Public Radio interview in February, 2009, he replied "I call myself a Possibilian: I'm open to ideas that we don't have any way of testing right now." In a subsequent interview with the New York Times, Eagleman expanded on the definition:
"Our ignorance of the cosmos is too vast to commit to atheism, and yet we know too much to commit to a particular religion. A third position, agnosticism, is often an uninteresting stance in which a person simply questions whether his traditional religious story (say, a man with a beard on a cloud) is true or not true. But with Possibilianism I'm hoping to define a new position -- one that emphasizes the exploration of new, unconsidered possibilities. Possibilianism is comfortable holding multiple ideas in mind; it is not interested in committing to any particular story."
An adherent of possibilianism is called a possibilian. The possibilian perspective is distinguished from agnosticism in that it consists of an active exploration of novel possibilities and an emphasis on the necessity of holding multiple positions at once if there is no available data to privilege one over the others. Possibilianism reflects the scientific temperament of creativity, testing, and tolerance for multiple ideas.

Kevin Kelly on possibilianism
Read technologist Kevin Kelly writing about the difference between agnosticism and possibilianism. An excerpt:
Agnostics end with the lack of an answer.
Possibilians begin with the lack of an answer.
Agnostics say, we can't decide between this and that.
Possibilians say, there are other choices than this or that.
Agnostics say, I Don't Know, it's impossible to answer that question.
Possibilians say, I Don't Know, there must be better questions.
