If it were the real character of lunacy, after the visitation of the paroxysm, to leave the patient in the possession of an _extremely sound mind_, this disorder would be rendered much less formidable than we now consider it, and might in its effects be compared to those violent storms of thunder and lightning that purify the atmosphere and dispense salutary refreshment; and it is not improbable, that some, gifted by nature with mediocrity of talent, but of a philosophical turn and aspiring pretensions, might regard the occurrence of such paroxysm as a desideratum, rather than an evil, on account of the _extreme soundness_ they would experience afterwards: it is moreover evident, that however degraded the lunatic may be in the estimation of vigorous and enlightened intellects, yet this depreciated object, by the enjoyment of occasional periods of bright understanding, has abundant cause for taunt and triumph over the victim of unsoundness; whose state is "contra-distinguished from lunacy," and as far as has been hitherto ascertained, does not revel in the luxury of a lucid interval. But these vicissitudes of intellectual obscurity and lustre have no real existence;--they are not the offsprings of observation and experience, but the abortions of hypothesis and precipitate deduction. Lunatics, from the excitation of various causes, become at times more violent or desponding, and these exacerbations are often succeeded by tranquillity and cheerfulness, they are more tractable, and less impelled to urge the subjects of their prevailing delusions: but this apparent quietude or assumed complacency, does not imply a renunciation of their perverted notions, which will be found predominant whenever they are skilfully questioned. Inexperienced persons judge of the insane state from the passions or feelings that usually accompany this disorder, and infer its aggravation from the display of boisterous emotions or afflicting apprehensions: the medical practitioner considers these sallies as the mere concomitants of a perverted intellect. This view of the subject is justified by a fact, of too much importance to be omitted on the present occasion. Many lunatics, whose dangerous propensities it has been prudent to control by a stricter restraint, and for a lengthened period, eventually become harmless, and are safely permitted to enjoy many indulgences incompatible with their former state: yet these persons retain their original delusions, although they have acquired the habit of arresting the impulses which these delusions prompted. It may therefore be inferred, that a lucid interval is equivalent to the complete recovery of the patient, and implies the absolute departure of _all_ those delusions from his mind, that constituted his lunacy:--leaving him in a condition to sustain a thorough examination, not shrinking from particular subjects, nor "blenching," though "tented to the quick;"--and clearly perceiving by contrast the delusions that
