There is no such thing as knowing a man intimately. Every soul is, for the greater part of its mortal life, isolated from every other. Whether it dwell in the Garden of Eden or the Desert of Sahara, it dwells alone. Not only do we jostle against the street crowd unknowing and unknown, but we go out and come in, we lie down and rise up, with strangers. Jupiter and Neptune sweep the heavens not more unfamiliar to us than the worlds that circle our own hearthstone. Day after day, and year after year a person moves by your side; he sits at the same table; he reads the same books; he kneels in the same church. You know every hair of his head, every trick of his lips, every tone of his voice; you can tell him far off by his gait. Without seeing him, you recognize his step, his knock, his laugh. "Know him? Yes, I have known him these twenty years." No, you don't know him. You know his gait, and hair, and voice. You know what preacher he hears, what ticket he voted, and what were his last year's expenses; but you don't know him. He sits quietly in his chair, but he is in the temple. You speak to him; his soul comes out into the vestibule to answer you, and returns,--and the gates are shut; therein you can not enter. You were discussing the state of the country; but when you ceased, he opened a postern-gate, went down a bank, and launched on a sea over whose waters you have no boat to sail, no star to guide. You have loved and reverenced him. He has been your concrete of truth and nobleness. Unwittingly you touch a secret spring, and a Blue-Beard chamber stands revealed. You give no sign; you meet and part as usual; but a Dead Sea rolls between you two forevermore. It must be so. Not even to the nearest and dearest can one unveil the secret place where his soul abideth, so that there shall be no more any winding ways or hidden chambers; but to your indifferent neighbor, what blind alleys, and deep caverns, and inaccessible mountains! To him who "touches the electric chain wherewith you're darkly bound," your soul sends back an answering thrill. One little window is opened, and there is short parley. Your ships speak each other now and then in welcome, though imperfect communication; but immediately you strike out again into the great, shoreless sea, over which you must sail forever alone. You may shrink from the far-reaching solitudes of your heart, but no other foot than yours can tread them, save those "That, eighteen hundred years ago, were nailed, For our advantage, to the bitter cross."
