It isn't that they can't see the solution. It's that they can't see the problem. They can't see the problem if they are looking in the wrong place. They can't see the problem if they have blinders on - for 'none are so blind as those that will not see'.
Gilbert K. ChestertonReal development is not leaving things behind, as on a road, but drawing life from them, as from a root.
