But how to determine, each man for himself, what is the direction of our development? A life becomes significant to itself so soon as it is conscious of its purpose, and it becomes harmonious as it makes all the details of experience subserve that purpose. The purpose of the individual life, so far as we can guess it, seems to be that the life shall be as complete as possible, that it shall fulfill itself and provide through its offspring for its continuance. It is true that no life is isolated; as every atom throughout the universe is bound to every other atom by subtlest filaments of influence, so each human life stands related to all other lives. But the man best pays his debt of service to others who makes the most of that which is given him to work with; and that is his own personality. We must begin at the centre and work outwards. My concern is with my own justice. If I worry because my friend or another is not just, I not only do not make him more just, but I also fail of the highest justice I can achieve, which is my own. We must be true to ourselves. We help one another not by precept but by _being;_ and what we are communicates itself. As physical life propagates and thus continues itself, so personality is transmitted in unconscious innumerable ways. The step and carriage of the body, the glance of the eye, the work of our hands, our silences no less than our speech, all express what we are. As everything follows upon what we are, so our responsibility is to _be,_ to be ourselves completely, perfectly.
