Gentlemen do not dream of reading lessons of craft to the like of doctors, lawyers, and professors; but they keenly relish the idea of crossing swords with criminologists, albeit the latter must be somewhat of doctor, lawyer and professor, in order to prescribe for what makes and keeps men criminal. Despite the fact that it is easier to bungle at the business of remodeling human clay than at any other activity on earth; and that the bungling works serious harm to humanity, the tinkerer sets up his moulds much in the spirit that a child builds with blocks, then tumbles them over, except for this difference: the child learns as he goes out of fancy and failure, while the grown-up wrecker remains anchored to his puerile notions and notebook. The machinery of a rational régime of reform must be carefully manipulated. Balance of parts depends upon a nice swing of correlated pendulums. Delicate adjustments encompass the ever shifting moods and susceptibilities of a prison population, in itself as a hair trigger to vibrate to unseemly disturbance of natural checks and impulses. A false edict out of the mouth of authority ofttimes is sufficient to start the prison pot a'boiling. A fool measure directed in favor of just one prisoner, without regard for how it fits into the general scheme, in the end may carry to adverse consequence that affects every prisoner in the place. Favoritism that singles out the few to the relative deprivation of the many, surely stirs up the latter, and can well do so the former. What is more, the harm done may not crop out in overt act of character whatsoever; but it will be most unfortunately expressed in such as listless work entailing lowering averages all along the reformative line. More quickly and more meticulously than any other herded group of humans, prisoners pick to pieces those charged with their destinies. Very naturally that is so. First, because the average criminal is pronouncedly ego-centric; and secondly, for the reason that the false throws of his supposed mentors and moulders, parallel in his mind his own oblique thinking and doing, and leave him no more to blame for what he did to society, than they for what they do to him. And there is more than a dash of equity in the criminal's specific conclusion. It is up to the criminologist to work skillfully and consistently with skilled tools. Moreover, the decent felon digs much more deeply to false methods than he usually discloses. Tempted, sorely, to make use of easy means to regain his liberty, and not being the dunce he is falsely tagged, he plays up to parole with the destructive weapons so obligingly placed in his hands; but he knows his exactions, and that "listless work entailing lowering averages all along the reformative line" does not meet them.
