"Kindness begets kindness and brings results. . . . Love, intelligently and humanely applied, has not only produced gentleness in the horse, but has contributed to the intelligence of the animal. And why does kindness contribute to intelligence? Because kindness is an attribute of intelligence. And like begets like. We know that restraint and self-control are necessary to the possession of the spirit of kindness, and these command the attention and submission of all domestic animals. . . . Why have the words of Jesus of Nazareth moved men to work and suffer, to think and feel as the words of no other man have done? It is the love, the intelligence, as well as the authority in which they were spoken. All nature responds to love. From love comes contentment, and the highest form of service."
