Nevertheless, as we have endeavoured to prove, it is immensely important that, while duly considering the relatively right, we should keep the absolutely right constantly in view. True as it is that, in this transition state, our conceptions of the ultimately expedient must ever be qualified by our experience of the proximately expedient; it is not the less true that the proximately expedient cannot be determined unless the ultimately expedient is known. Before we can say what is as good as the time permits, we must say what is abstractedly good; for the first idea involves the last. We must have some fixed standard, some invariable measure, some constant clue; otherwise we shall inevitably be misled by the suggestions of immediate policy, and wander away from the right rather than advance towards it. This conclusion is fully borne out by the facts we have cited. In other cases, as well as in the case of penal discipline, the evidence shows how terribly we have erred from obstinately refusing to consult first principles and clinging to an unreasoning empiricism. Though, during civilization, grievous evils have occasionally arisen from attempts suddenly to realize absolute rectitude, yet a {189} greater sum total of evils has arisen from the more usual course of ignoring absolute rectitude. Age after age, effete institutions have been maintained far longer than they would else have been, and equitable arrangements have been needlessly postponed. Is it not time for us to profit by past lessons? * * * * * POSTSCRIPT.—Since the publication of this essay in 1860 further evidence supporting its conclusions has been made public. Dr. F.J. Mouat, late Inspector-General of Gaols in Lower Bengal, has given, in various pamphlets and articles, dating from 1872, accounts of his experiences, which entirely harmonize with the foregoing general argument. Speaking of three leading systems of prison-discipline, “based on opposite theories,” he says:― “The oldest is, that a prison should be rendered a terror to evil doers by the infliction of as much pain as can be inflicted, without direct injury to health or risk to life. The second plan is a graduated system of punishment, from which the direct infliction of pain is eliminated, and the prisoner is allowed to work his way to freedom and mitigation of sentence, by mere good conduct in jail. The third, and in my humble judgment the best, is to convert every prison into a school of industry, labour being used as an instrument of punishment, discipline, and reformation.”—_Prison Industry in its Primitive, Reformatory, and Economic Aspects_ (London, Nov. 1889). In his pamphlet on the _Prison System of India_, published in 1872, Dr. Mouat contends:―
