In a list of definitions included in the authentic translation of Plato, a list attributed to him, occurs this: ‘Natural Depravity: a depravity according to nature.’ A definition which though savouring of Calvinism, by no means involves Calvin’s dogma as to total mankind. Evidently its intent makes it applicable but to individuals. Not many are the examples of this depravity which the gallows and jail supply. At any rate, for notable instances,--since these have no vulgar alloy of the brute in them, but invariably are dominated by intellectuality,--one must go elsewhere. Civilisation, especially if of the austerer sort, is auspicious to it. It folds itself in the mantle of respectability. It has its certain negative virtues serving as silent auxiliaries. It is not going too far to say that it is without vices or small sins. There is a phenomenal pride in it that excludes them from anything--never mercenary or avaricious. In short, the depravity here meant partakes nothing of the sordid or sensual. It is serious, but free from acerbity. Though no flatterer of mankind, it never speaks ill of it. But the thing which in eminent instances signalises so exceptional a nature is this: though the man’s even temper and discreet bearing would seem to intimate a mind peculiarly subject to the law of reason, not the less in his soul’s recesses he would seem to riot in complete exemption from that law, having apparently little to do with reason further than to employ it as an ambidexter implement for effecting the irrational. That is to say: toward the accomplishment of an aim which in wantonness of malignity would seem to partake of the insane, he will direct a cool judgment sagacious and sound. These men are true madmen, and of the most dangerous sort, for their lunacy is not continuous, but occasional; evoked by some special object; it is secretive and self-contained, so that when most active it is to the average mind not distinguished from sanity, and for the reason above suggested that whatever its aim may be, and the aim is never disclosed, the method and the outward proceeding is always perfectly rational. Now something such was Claggart, in whom was the mania of an evil nature, not engendered by vicious training or corrupting books or licentious living, but born with him and innate, in short, ‘a depravity according to nature.’
