“Nothing is so sweet to the heart of man as love. However, for love to function, the suppression of sympathy may be necessary. A surgeon would be a failure if he indulged his natural sympathy at the sight of a bleeding wound. He must suppress his emotion to save a life, he must hurt in order to heal. Genuine love, genuine mercy, must not be taken to be indulgence of mere feeling, excess of sensibility, which is commonly called sentimentality.”*----------------------------/
