Sympathy is an eye to discern, a lever to raise, an arm to sustain. The service to the world that has been done by the great thinkers––the poets and the artists––and by the great doers––the heroes––is, that they have put out feelers, as it were, for our Sympathy. A picture or poem, or the story of a noble deed, 'finds' us, we say. We, too, think that thought or live in that action, and, immediately, we are elevated and sustained. This is the sympathy we owe to our fellows, near and far off. If we have anything good to give, let us give it, knowing with certainty that they will respond. If we fail to give this Sympathy, if we regard the people about us as thinking small, unworthy thoughts, doing mean, unworthy actions, and incapable of better things, we reap our reward. We are really, though we are not aware of it, giving Sympathy to all that is base in others, and thus strengthening and increasing their baseness: at the same time we are shutting ourselves into habits of hard and narrow thinking and living.
