Soon, however, it begins to experience the happiness resulting from the relations of minds to each other, and then is developed the superior power of _love_, and its importance as a regulating principle. In the analysis of this affection, it is seen to consist, first, in the pleasurable emotions which arise in view of those traits of character in another mind pointed out on previous pages. When these qualities are discovered, the first result is emotions of pleasure in the contemplation. Immediately there follows _a desire of good_ to the cause of this pleasure. Next follows the desire of reciprocated affection--that is, a desire is awakened _to become the cause of the same pleasure_ to another; for the desire of _being loved_ is the desire to be the cause of pleasurable emotions in another mind, in view of our own good qualities. When we secure this desired appreciation, then follows an increased _desire of good_ to the one who bestows it. Thus the affection of love is a combination of the action and reaction of pleasurable emotions, all tending to awaken the desire of good to another. This passion may become so intensified that it will become more delightful to secure enjoyments to another than to procure them for self. Gratitude is the emotion of pleasure toward the author of _voluntary_ good to self, attended by a desire of good to the benefactor. This principle can be added to augment the power of love. There is a foundation for a very important distinction in the analysis of the principle of love. In what is thus far presented, we find that the desire of good to another results solely from the fact that certain mental qualities are _causes of pleasure to self_. Of course, this desire ceases when those qualities cease to exist or cease to be appreciated. This kind of love is the natural result of the constitution of minds in their relations to each other, making it _easy and pleasant_ to live for the good of another in return for the pleasure received from their agreeable qualities and manifestations. But the highest kind of love consists in the _desire of good to another without reference to any good received in return_. It is _good willing_. It consists in an abiding feeling of desire for the happiness of another mind.
