There are men and women whose presence seems to radiate sunshine, cheer and optimism. You feel calmed and rested and restored in a moment to a new and stronger faith in humanity. There are others who focus in an instant all your latent distrust, morbidness and rebellion against life. Without knowing why, you chafe and fret in their presence. You lose your bearings on life and its problems. Your moral compass is disturbed and unsatisfactory. It is made untrue in an instant, as the magnetic needle of a ship is deflected when it passes near great mountains of iron ore. There are men who float down the stream of life like icebergs,--cold, reserved, unapproachable and self-contained. In their presence you involuntarily draw your wraps closer around you, as you wonder who left the door open. These refrigerated human beings have a most depressing influence on all those who fall under the spell of their radiated chilliness. But there are other natures, warm, helpful, genial, who are like the Gulf Stream, following their own course, flowing undaunted and undismayed in the ocean of colder waters. Their presence brings warmth and life and the glow of sunshine, the joyous, stimulating breath of spring. There are men who are like malarious swamps,--poisonous, depressing and weakening by their very presence. They make heavy, oppressive and gloomy the atmosphere of their own homes; the sound of the children's play is stilled, the ripples of laughter are frozen by their presence. They go through life as if each day were a new big funeral, and they were always chief mourners. There are other men who seem like the ocean; they are constantly bracing, stimulating, giving new draughts of tonic life and strength by their very presence. There are men who are insincere in heart, and that insincerity is radiated by their presence. They have a wondrous interest in your welfare,--when they need you. They put on a "property" smile so suddenly, when it serves their purpose, that it seems the smile must be connected with some electric button concealed in their clothes. Their voice has a simulated cordiality that long training may have made almost natural. But they never play their part absolutely true, the mask _will_ slip down sometimes; their cleverness cannot teach their eyes the look of sterling honesty; they may deceive some people, but they cannot deceive all. There is a subtle power of revelation which makes us say: "Well, I cannot explain how it is, but I know that man is not honest." Man cannot escape for one moment from this radiation of his character, this constantly weakening or strengthening of others. He cannot evade the responsibility by saying it is an unconscious influence. He can _select_ the qualities that he will permit to be radiated. He can cultivate sweetness, calmness, trust, generosity, truth, justice, loyalty, nobility,--make them vitally active in his character,--and by these qualities he will constantly affect the world.
