It is the power of making the world happy, or at least of so greatly diminishing the amount of unhappiness in it as to make it quite a different world from what it is at present. This power is called kindness. The worst kinds of unhappiness, as well as the greatest amount of it, come from our conduct to each other. If our conduct therefore were under the control of kindness, it would be nearly the opposite of what it is, and so the state of the world would almost be reversed.
