Adventure is humdrum and routine unless one assimilates it, unless one relates it to a central core which grows within and gives it contour and significance. Raw experience is empty, just as empty as the forecastle of a whaler as in a chamber of a counting house; for it is not what one does, but in a manifold sense, what one realizes that keeps existence from being vain and trivial.
