"I do not, in my private capacity, believe that a baby gets his best physical food by sucking his thumb; nor that a man gets his best moral food by sucking his soul, and denying its dependence on God or other good things. I would maintain that thanks are the highest form of thought; and that gratitude is happiness doubled by wonder."
