The zeal which defends truly conjugial love is the highest form of zeal, because that is the highest form of love, and the pleasures it is anxious to protect are the highest forms of pleasure. For, as was shown above [64], that love is the chief of all loves. The reason is that this love makes a wife a form of love and a husband a form of wisdom; and these two forms united into one cannot produce anything which is not touched by wisdom and at the same time by love. Since the zeal of conjugial love is the highest form of zeal, it acquires a new name and is called jealousy, as being a model of zeal.* * Latin zelotypia 'jealousy' is a Greek loan-word, a compound of zelus 'zeal' and typus 'model, type'.
