As quoted in "Stray Questions for: David Eagleman" by Blake Wilson in The New York Times (10 July 2009) http://artsbeat.blogs.nytimes.com/2009/07/10/stray-questions-for-david-eagleman/
Context: 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.

The Tragic Sense of Life (1913), IV : The Essence of Catholicism
Context: ... as the great Unitarian preacher Channing pointed out, that in France and Spain there are multitudes who have proceeded from rejecting Popery to absolute atheism, because "the fact is, that false and absurd doctrines, when exposed, have a natural tendency to beget skepticism in those who receive them without reflection. None are so likely to believe too little as those who have begun by believing too much." Here is, indeed, the terrible danger of believing too much. But no! the terrible danger comes from another quarter — from seeking to believe with the reason and not with the life.
