Moral Functions as Interests.

If morality consists in the exercise of one's specific functions, it follows that no detailed account of the content of the moral end can possibly be given. This content is thoroughly individual or infinite. It is concrete to the core, including every detail of conduct, and this not in a rigid formula, but in the movement of life. All we can do is, by abstraction, to select some of the main features of the end, such as the more common and the more permanent. While each individual has his own particular functions, which can no more be exhausted by definition or description than the qualities of any other individual object, it is also true that we can recognize certain typical functions to be found permanently and in all. These make, as it were, the skeleton of the moral end which each clothes with his own flesh and blood.

Functions are interests—objective interests were not the term tautological. Interests have three traits worth special mention.

1. They are active. An interest is not an emotion produced from without. It is the reaction of the emotion to the object. Interest is identified, in ordinary speech, with attention; we take an interest, or, if we say simply 'interested,' that involves some excitation, some action just beginning. We talk of a man's interests, meaning his occupations or range of activities.

2. They are objective. The emotion aroused goes out to some object, and is fixed upon that; we are always interested in something. The active element of interest is precisely that which takes it out of the inner mood itself and gives it a terminus, an end in an object.

3. An interest is satisfaction. It is its own reward. It is not a striving for something unrealized, or a mere condition of tension. It is the satisfaction in some object which the mind already has. This object may be possessed in some greater or less degree, in full realization or in faint grasp, but interest attaches to it as possessed. This differentiates it from desire, even where otherwise the states are the same. Desire refers to the lack, to what is not present to the mind. One state of mind may be called both interest in, and desire for, knowledge, but desire emphasizes the unknown, while interest is on account of the finding of self, of intelligence, in the object. Interest is the union in feeling, through action, of self and an object. An interest in life is had when a man can practically identify himself with some object lying beyond his immediate or already acquired self and thus be led to further expression of himself.

To have an interest, then, is to be alert, to have an object, and to find satisfaction in an activity which brings this object home to self.

Not every interest carries with it complete satisfaction. But no interest can be wholly thwarted. The purer the interest, the more the interest is in the object for its own sake, and not for that of some ulterior consequence, the more the interest fulfills itself. "It is better to have loved and lost than never to have loved at all", and love is simply the highest power of interest—interest freed from all extrinsic stuff.
