particular theoretical controversy, the term 'unselfishness' refers to the kind of aims and objects which habitually interest a man. And if we make a mental survey of the kind of interests which evoke the use of this epithet, we shall see that they have two intimately associated features. (i) The generous self consciously identifies itself with the full range of relationships implied in its activity, instead of drawing a sharp line between itself and considerations which are excluded as alien or indifferent; (ii) it readjusts and expands its past ideas of itself to take in new consequences as they become perceptible. When the physician began his career he may not have thought of a pestilence; he may not have consciously identified himself with service under such conditions. But, if he has a normally growing or active self, when he finds that his vocation involves such risks, he willingly adopts them as integral portions of his activity. The wider or larger self which means inclusion instead of denial of relationships is identical with a self which enlarges in order to assume previously unforeseen ties.
In such crises of readjustment—and the crisis may be slight as well as great—there may be a transitional conflict of 'principle' with 'interest.' It is the nature of a habit to involve ease in the accustomed line of activity. It is the nature of a readjusting of habit to involve an effort which is disagreeable—something to which a man has deliberately to hold himself. In other words, there is a tendency to identify the self—or take interest—in what one has got used to, and to turn away the mind with aversion or irritation when an unexpected thing which involves an unpleasant modification of habit comes up. Since in the past one has done one's duty without having to face such a disagreeable circumstance, why not go on as one has been? To yield to this temptation means to narrow and isolate the thought of the self—to treat it as complete. Any habit, no matter how efficient in the past, which has become set, may at any time bring this
