And when he grows to manhood, what then? Why he dies, and so becomes alive. The caddis-fly leaves his tube behind and soars into the upper air; the creature abandons its barnacle existence on the rock and swims at large in the sea. For it is just when we die to custom that, for the first time, we rise into the true life of humanity; it is just when we abandon all prejudice of our own superiority over others, and become convinced of our entire indefensibleness, that the world opens out with comrade faces in all directions; and when we perceive how entirely arbitrary is the setting of our own life, that the whole structure collapses on which our apartness from others rests, and we pass easily and at once into the great ocean of freedom and equality. This is, as it were, a new departure for man, for which even to-day the old world, overlaid with myriad customs now brought into obvious and open conflict with each other, is evidently preparing. The period of human infancy is coming to an end. Now comes the time of manhood and true vitality. Possibly this is a law of history, that when man has run through every variety of custom a time comes for him to be freed from it--that is, he uses it indifferently according to his requirements, and is no longer a slave to it; all human practices find their use, and none are forbidden. At this point, whenever reached, "morals" come to an end and humanity takes its place--that is to say, there is no longer any code of action, but the one object of all action is the deliverance of the human being and the establishment of equality between oneself and another, the entry into a new life, which new life when entered into is glad and perfect, because there is no more any effort or strain in it; but it is the recognition of oneself in others, eternally. Far as custom has carried man from man, yet when at last in the ever-branching series the complete human being is produced, it knows at once its kinship with all the other forms. "I have passed my spirit in determination and compassion round the whole earth, and found only equals and lovers." More, it knows its kinship with the animals. It sees that it is only habit, an illusion of difference, that divides; and it perceives after all that it is the same human creature that flies in the air, and swims in the sea, or walks biped upon the land.
