“Nothing is more noble, nothing more venerable than fidelity. Faithfulness and truth are the most sacred excellences and endowments of the human mind.”
“Constancy has nothing virtuous in itself, independently of the pleasure it confers, and partakes of the temporizing spirit of vice in proportion as it endures tamely moral defects of magnitude in the object of its indiscreet choice.”
“What a fuss people make about fidelity! Why, even in love it is purely a question for physiology. It has nothing to do with our own will. Young men want to be faithful, and are not; old men want to be faithless, and cannot: that is all one can say.”
“People who love only once in their lives are shallow people. What they call their loyalty, and their fidelity, I call either the lethargy of custom or their lack of imagination. Faithfulness is to the emotional life what consistency is to the life of the intellect -- simply a confession of failures.”
