Imagination

In very truth, a wise imagination, which is the presence of the spirit of God, is the best guide that man or woman can have; for it is not the things we see the most clearly that influence us the most powerfully; undefined, yet vivid visions of something beyond, something which eye has not seen nor ear heard, have far more influence than any logical sequences whereby the same things may be demonstrated to the intellect. It is the nature of the thing, not the clearness of its outline, that determines its operation. We live by faith, and not by sight.

--George MacDonald
