This new evil seems no less deadly in its effects than an exaggerated personal ambition. Our complex social conditions render us in many respects more dependent on one another than formerly. We have associations and co-operations for everything. Increase of population and means of communication bring us more into contact with our fellows. Division of labour makes us indispensable to one another. We all govern one another. We all have, in some form, a voice in public concerns. Under the guise of advancing the common good, we have special opportunities for advancing Self; and it is the element of self-deception introduced into our striving after self-advancement, and our consequent habit of deceiving others, which are specially injurious to our moral sense. Marcus Aurelius tells us that that which is not for the interest of the whole hive is not for the interest of a single bee. He might with equal truth have said that that which is not for the higher interests of a single bee cannot in the long-run benefit the hive. It may be questioned whether our exceeding unrest, our yearning for notoriety, our eagerness to overwork ourselves, _i.e._, to draw on our nerve-capital at the risk of breaking the bank, are not symptoms of widespread nervous disease in the community rather than its causes; just as, in the individual, the restless excitement regarded often as the cause of the after-malady is in reality but a symptom of the disintegration which has already begun. We may console ourselves with the reflection that, neurasthenia in the individual being curable, neurasthenia in the community is curable also; the community being but a collection of individuals.
