Lord Rosebery, who can make proverbs as well as cite them, lately recalled one which has had great vogue in its day, namely, "Let bygones be bygones." Life would be impossible or very unpleasant if every one persisted in remembering what had better be forgotten. Proverbs are like plants: they have a soil and climate under which alone they flourish. Noble maxims have their limitations. Few have universal applicability. If, for instance, the advice to "let bygones be bygones" be taken as universally true, strange questions arise. Are mistakes never more to teach us what to avoid? Are the errors of others no more to be a warning to us? Is the Book of Experience to be closed? Is no more history to be written? If so philosophy could no longer teach wisdom by examples, for there would no longer be any examples to go upon. If all the mistakes of mankind and all the miscalculations of circumstance be forgotten, the warnings of the sages will die with them. He who has debts, or loans not repaid, or promises not kept, or contracts unfulfilled in his memory, had better keep them there until he has made what reparation he can. The Bygone proverb does not apply to him. There are other derelictions of greater gravity than fall under the head of intellectual petty larceny, such as the conscious abandonment of principle, or desertion of a just cause, which had better be kept in mind for rectification. If an admiral wrecked his ships, or a general lost his army, or a statesman ruined his country, by flagrant want of judgment--ever so conscientiously--it is well such things should be borne in mind by those who may renew, by fresh appointment, these opportunities of calamity. It would be to encourage incapacity were such bygones consigned to oblivion. It may be useless to dwell upon "spilt milk," but further employment of the spiller may not be prudent. Slaves of the saying, "Let bygones perish," would construct mere political man-traps, which never act when depredators are about. In human affairs bygones have occurred worth remembering as guides for the future. It is said that "greatness is thrust upon a man"--what is meant is a position of greatness. Greatness lies in the quality of the individual, and cannot be "thrust" on any man. It is true that intrinsic greatness is often left unrecognised. It would be a crime against progress were these cases, when known, consigned to forgetfulness. Noble thoughts as well as noble acts are worth bearing in mind, however long ago they may have occurred.
