Founding Address (1876), Life and Destiny (1913) 
Context: It is not possible to enter into the nature of the Good by standing aloof from it — by merely speculating upon it. Act the Good, and you will believe in it. Throw yourself into the stream of the world's good tendency and you will feel the force of the current and the direction in which it is setting. The conviction that the world is moving toward great ends of progress will come surely to him who is himself engaged in the work of progress.
By ceaseless efforts to live the good life we maintain our moral sanity. Not from without, but from within, flow the divine waters that renew the soul.
                                    
“There is in each of us a stream of tendency, whether you choose to call it philosophy or not, which gives coherence and direction to thought and action. Judges cannot escape that current any more than other mortals.”

Context: There is in each of us a stream of tendency, whether you choose to call it philosophy or not, which gives coherence and direction to thought and action. Judges cannot escape that current any more than other mortals. All their lives, forces which they do not recognize and cannot name, have been tugging at them — inherited instincts, traditional beliefs, acquired convictions; and the resultant is an outlook on life, a conception of social needs. … In this mental background every problem finds it setting. We may try to see things as objectively as we please. None the less, we can never see them with any eyes except our own.

                                        Sejamos simples e calmos,
Como os regatos e as árvores,
E Deus amar-nos-á fazendo de nós
Belos como as árvores e os regatos,
E dar-nos-á verdor na sua primavera,
E um rio aonde ir ter quando acabemos...
E não nos dará mais nada, porque dar-nos mais seria tirar-nos mais.
