(1) There has been much dispute as to whether the sense of duty or moral obligation can or cannot be analyzed. It has been declared unanalyzable and unique. Some think this a point of much importance which imparts a peculiar sacredness to the sense of duty. There appears no reason why this position should be taken. No one has been able to analyze into its ultimate sensational elements the peculiar feeling one has when one is tickled. But this does not make the feeling sacred or awe-inspiring. The authority of the sense of duty must be looked for in another direction--and authority it has. (2) I have spoken of the "sense" of duty. We all recognize that, when we are faced with a duty, a feeling is normally present. But the whole argument of this volume has maintained that man is not to be treated only as the subject of emotions. He is a rational being. In some persons feeling is very prominent; in others it is less so. It is quite conceivable that, in a given case, a man capable of reflection should recognize that he is confronted with a duty, and yet that he should feel no impulse to perform it. Did no one ever feel any such impulse, the whole system of duties, the whole rational order of society itself, would dissolve and disappear. Fortunately, the normal man does feel an impulse to perform duties recognized as such. And in the case of those exceptional persons who do not, society strives to supply surrogates, extraordinary impulses based upon a system of rewards and punishments. This is a mere supplement, and could never keep alive a society from which the sense of duty had disappeared. Duty _is_ sacred. It is the very foundation of every rational society. It does not greatly concern ethics whether the impulse, which makes itself felt in men who want to do their duty, can or cannot be analyzed. But it is all-important that they should feel the impulse. (3) Can a man do more than his duty? Is it the duty of everyone to be, not merely a good, average, honest, faithful, law-abiding citizen, but to go far beyond this and be conspicuously a saint? It should be remembered that we are concerned with the connotation properly to be given to a word in common use. A certain amount of goodness the social will appears to demand of men rather peremptorily. Its demands seem to vary somewhat with the exigencies of the times--for example, in peace and in war. It does not make the same demands of all men. From those to whom much has been given-- wealth, education, social or political influence,--much is required. From certain persons it appears to be glad to get anything. If they keep out of the police-court, it is agreeably surprised.
