All power operates on a narrow basis; it rests on a few chosen faculties, and always ruthless exploits the weak. But history hast shown again and again that the weak of the present have become the strong of the future, whereas power of today has provided the ruins of to-morrow. Who can know today that attributes and capacities will be vital in a thousand years' time? Only the preservation of all our attributes, including our weaknesses, can carry us safely through into the uncertain future. But how can it be done? Certainly not by force which does not preserve but destroys. There is only one thing which preserves all things, including the weak, and that is love.
