Here I close my description of these old cases, conceiving I have given a sufficient number for the purpose I had in view, that of exhibiting a fair average picture of the state and character of the old insane. After one general abstract observation on the whole essay, I shall afterwards, and following this last case, make my next essay on the origin and nature of disease in general, and of insanity in particular: and which I shall do as preliminary to the more intimate and direct investigation of the causes and nature of insanity; and especially the direct consideration of the cause to which I have alluded in this case, because it is one of the most general and most fatal causes of insanity, and a cause, which if not removed, inevitably renders them incurable. Such was the habit of the person whose case obliged me very reluctantly to assume a defensive attitude, and refute falsehood by a statement of the truth, or otherwise I should have continued silently to proceed in the path of duty, without obtruding our own secret exertions on the notice of the public, as it may appear that I have done in this essay, as well as in those which are to follow, written, as they will be, in some measure on the same principle, for the truth should not suffer from diffidence, any more than it ought to be brought into disrepute by vain ostentation; still, I am quite certain, that I am actuated by no feelings incompatible with charity and justice. CONCLUDING OBSERVATIONS. The concluding general observations on this Essay and its Appendix, are, that the one principal object I have had constantly in view, has been the removal of the erroneous impressions and prejudices which exist almost universally against the insane, as if they alone were all furious wild beasts or infernal demons, and which have hitherto excited and still continue to excite a spirit and conduct toward them, productive of a baneful and injurious influence. So long as these prejudices exist in the mind, even the soothing treatment which is now so much the boast of the age, assumes a spirit and manner, perhaps as galling and injurious to the afflicted as was, undoubtedly, the heartless tyranny of former times. I deprecate that altered tone of voice and manner which implies in every word and action, that they are considered either as children, or as beings wholly bereft of rationality.
