I know that it is a very wise injunction, that every man should mind his own business; and that, if every man would only do that, the world would go on as well as heart could wish. I believe this, firmly. But then, since, in the very constitution of things, every man's 'own business' is inextricably interwoven with every other man's 'own business,' who shall draw the line? Who shall define the circle and the sphere of the private individual? Has not our Creator defined it already in our very being, inasmuch as, by the indestructible ties of human sympathy and a common nature, he has bound up the life, the interests, the business of the individual, with the life, the interests, the business of the whole? By his very nature, then, is it not every man's own business to know what the world is busy about, and to take an interest in the world's affairs, because they are his own? Is it not a truth written in the constitution of every individual man, the well-known declaration of the Roman slave: 'I am a man, and I hold nothing human foreign to me?' And does not our common Christianity teach over and over again in a thousand ways, that we are all members one of another, and that no man lives for himself? And is there any one fact, which the progress of events is now making, more manifest than the oneness of all mankind? Why, my hearers, it is because this simple and indestructible fact is not seen; because individuals are for ever trying to live, and work, and enjoy, not with and for, but at the expense of, their fellow-men, that things are so continually getting out of joint, and the world is so full of uproar and misery. My brothers, we are all One; and if we are resolved to mind each his own business, we must attend to the business which God and nature have given to us. We must interest ourselves in the cause of our common humanity. I do not say, that we must make this great cause our business. It is made our business already by our Maker.
