It is when the sentimentalist turns preacher of morals that we investigate his character, and are justified in so doing. He may express as many and as delicate shades of feeling as he likes, — for this the sensibility of his organization perfectly fits him, no other person could do it so well, — but the moment he undertakes to establish his feeling as a rule of conduct, we ask at once how far are his own life and deed in accordance with what he preaches? For every man feels instinctively that all the beautiful sentiments in the world weigh less than a single lovely action; and that while tenderness of feeling and susceptibility to generous emotions are accidents of temperament, goodness is an achievement of the will and a quality of the life. Fine words, says our homely old proverb, butter no parsnips; and if the question be how to render those vegetables palatable, an ounce of butter would be worth more than all the orations of Cicero. The only conclusive evidence of a man’s sincerity is that he give himself for a principle. Words, money, all things else, are comparatively easy to give away; but when a man makes a gift of his daily life and practice, it is plain that the truth, whatever it may be, has taken possession of him.
