{13} The character of Grimes, his obduracy and apparent want of feeling, his gloomy kind of misanthropy, the progress of his madness, and the horrors of his imagination, I must leave to the judgment and observation of my readers.  The mind here exhibited is one untouched by pity, unstung by remorse, and uncorrected by shame; yet is this hardihood of temper and spirit broken by want, disease, solitude, and disappointment:  and he becomes the victim of a distempered and horror-stricken fancy.  It is evident, therefore, that no feeble vision, no half-visible ghost, not the momentary glance of an unbodied being, nor the half-audible voice of an invisible one, would be created by the continual workings of distress on a mind so depraved and flinty.  The ruffian of Mr Scott (Marmion) has a mind of this nature; he has no shame or remorse, but the corrosion of hopeless want, the wasting of unabating disease, and the gloom of unvaried solitude, will have their effect on every nature and the harder that nature is, and the longer time required to work upon it, so much the more strong and indelible is the impression.  This is all the reason I am able to give, why a man of feeling so dull should yet become insane, and why the visions of his distempered brain should be of so horrible a nature.

{14} That a Letter on Prisons should follow the narratives of such characters as Keene and Grimes is unfortunate, but not to be easily avoided.  I confess it is not pleasant to be detained so long by subiects so repulsive to the feelings of many as the sufferings of mankind; but, though I assuredly would have altered this arrangement, had I been able to have done it by substituting a better, yet am I not of opinion that my verses, or, indeed, the verses of any other person, can so represent the evils and distresses of life as to make any material impression on the mind, and much less any of injurious nature.  Alas! sufferings real, evident, continually before us, have not effects very serious or lasting, even in the minds of the more reflecting and compassionate; nor, indeed, does it seem right that the pain caused by sympathy should serve for more than a stimulus to benevolence.  If then the strength and solidity of truth placed before our eyes have effect so feeble and transitory, I need not be very apprehensive that my representations of Poor-houses and Prisons, of wants and sufferings, however faithfully taken, will excite any feelings which can be seriously lamented.  It has always been held as a salutary exercise of the mind to contemplate the evils and miseries of our nature:  I am not therefore without hope that even this gloomy subject of Imprisonment, and more especially the Dream of the Condemned Highwayman, will excite in some minds that mingled pity and abhorrence which, while it is not unpleasant to the feelings, is useful in its operation.  It ties and binds us to all mankind by sensations common to us all, and in some degree connects us, without degradation, even to the most miserable and guilty of our fellow-men.
