"What is the use of this fuss about morality when the issue only involves a horse? The first and most difficult teaching of civilization concerns man's behavior to his inferiors. Make humanity gentle or reasonable toward animals, and strife or injustice between human beings would speedily terminate."
"Our lives are fed by kind words and gracious behavior. We are nourished by expressions like excuse me and other such simple courtesies... Rudeness, the absence of the sacrament of consideration, is but another mark that our time-is-money society is lacking in spirituality, if not also in its enjoyment of life."
