But I still underestimate the prevalence of the principle. Our instances must be homelier yet. Each day come petty citations to self- sacrifice which are accepted as a matter of course. As I walk to my lecture-room somebody stops me and says, "What is the way to Berkeley Street?" Do I reprovingly answer, "You must have made a mistake. I have no interest in Berkeley Street. I think it is you who are going there, and why are you putting me to inconvenience merely that you may the more easily find your way?" Should I answer so, he would think and possibly say, "There are strange people in Cambridge, remoter from human kind than any known elsewhere." Every one would feel astonishment at the man who declined to bear his little portion of a neighbor's burden. Our commonest acceptance of society involves self- sacrifice, and in all our trivial intercourse we expect to put ourselves to unrewarded inconvenience for the sake of others. VII What I have set myself to make plain in this series of graded examples is simply this: self-sacrifice is not something exceptional, something occurring at crises of our lives, something for which we need perpetually to be preparing ourselves, so that when the great occasion comes we may be ready to lay ourselves upon its altar. Such romanticism distorts and obscures. Self-sacrifice is an everyday affair. By it we live. It is the very air of our moral lungs. Without it society could not go on for an hour. And that is precisely why we reverence it so--not for its rarity, but for its importance. Nothing else, I suppose, so instantly calls on the beholder for a bowing of the head. Even a slight exhibit of it sends through the sensitive observer a thrill of reverent abasement. Other acts we may admire; others we may envy; this we adore.
