of purity, a devotion to purity, and flying from the first insi- 

 dious approaches of evil are the remedies to be relied on. And 

 when religion is a real, earnest, practical faith, entering into the 

 whole life, living in good works of piety and charity not a 

 mere sentimentalism, or trying to feel good, but rather a trying 

 to do good and the whole life is one consistent prayer for the 

 highest and purest love, bad men, living in sensuality, will 

 have no power to injure. 



What is jealousy, and what are its uses? Every passion 

 thwarted gives us pain. Every object of desire wrested from 

 us is a cause of grief, which may be accompanied by feelings 

 of hatred and revenge. The loss of what we prize, what we 

 have a property in, or a right to, is painful. We are jealous of 

 our property, our position, our reputation, and most of all jealous 

 of those we love. But the element of selfishness shows itself 

 most strongly in our sexual relations. We are willing to, share 

 our friends, our fortune, our common pleasures with others. 

 The enjoyment of others heightens our own. A man likes to 

 have his dinners relished, his pictures enjoyed, his music 

 applauded, his children praised, his wife admired; but whatever 

 a man wants exclusive possession of whatever he loves with a 

 selfish and exclusive love, he will be jealous of. If we grant 

 the right of exclusive love and possession, we must admit the 

 utility of the pain and passion that guard it. We have love 

 and honour as our guarantees on one side ; on the other, pain 

 and fear. Perfect love casteth out fear casteth out jealousy. 



People say, where there is reason for love, there can be no 

 reason for jealousy, and vice versa. But love itself is not always 

 reasonable. With entire trust there can, of course, be no dis- 

 trust ; but perfect trust can come only of perfection the sense 

 of perfection in ourselves, and the recognition of perfection 

 in another. A high estimation of one's self is a great protec- 

 tion from jealousy, which often comes from morbid humility 

 and morbid approbativeness. We feel unworthy to be loved;
