"Custom hangs upon us with a weight Heavy as frost, and deep almost as life." This power and depth are, however, just what give value to custom, when it works with life, instead of against it. The high ethical training, of a nation being threefold, of body, heart, and practice (compare the statement in the preface to "Unto This Last"), involves exquisiteness in all its perceptions of circumstance,--all its occupations of thought. It implies perfect Grace, Pitifulness, and Peace; it is irreconcilably inconsistent with filthy or mechanical employments,--with the desire of money,--and with mental states of anxiety, jealousy, and indifference to pain. The present insensibility of the upper classes of Europe to the aspects of suffering, uncleanness, and crime, binds them not only into one responsibility with the sin, but into one dishonour with the foulness, which rot at their thresholds. The crimes daily recorded in the police courts of London and Paris (and much more those which are unrecorded) are a disgrace to the whole body politic;[104] they are, as in the body natural, stains of disease on a face of delicate skin, making the delicacy itself frightful. Similarly, the filth and poverty permitted or ignored in the midst of us are as dishonourable to the whole social body, as in the body natural it is to wash the face, but leave the hands and feet foul. Christ's way is the only true one: begin at the feet; the face will take care of itself. Yet, since necessarily, in the frame of a nation, nothing but the head can be of gold, and the feet, for the work they have to do, must be part of iron, part of clay;--foul or mechanical work is always reduced by a noble race to the minimum in quantity; and, even then, performed and endured, not without sense of degradation, as a fine temper is wounded by the sight of the lower offices of the body. The highest conditions of human society reached hitherto, have cast such work to slaves;--supposing slavery of a politically defined kind to be done away with, mechanical and foul employment must in all highly-organized states take the aspect either of punishment or probation. All criminals should at once be set to the most dangerous and painful forms of it, especially to work in mines and at furnaces,[105] so as to relieve the innocent population as far as possible: of merely rough (not mechanical) manual labour, especially agricultural, a large portion should be done by the upper classes;--bodily health, and sufficient contrast and repose for the mental functions, being unattainable without it; what necessarily inferior labour remains to be done, as especially in manufactures, should, and always will, when the relations of society are reverent and harmonious, fall to the lot of those who, for the time, are fit for nothing better. For as, whatever the perfectness of the educational system, there must remain infinite differences between the natures and capacities of men; and these differing natures are
