At six o'clock he sat down to his library table, which was a plain ordinary piece of furniture, and read till dusk. During this period of dubious light, so friendly to thought, he rested in tranquil meditation on what he had been reading, provided the book were worth it; if not, he sketched his lecture for the next day, or some part of any book he might then be composing. During this state of repose he took his station winter and summer by the stove, looking through the window at the old tower of Lobenicht; not that he could be said properly to see it, but the tower rested upon his eye,—obscurely, or but half revealed to his consciousness. No words seemed forcible enough to express his sense of the gratification which he derived from this old tower, when seen under these circumstances of twilight and quiet reverie. The sequel, indeed, showed how important it was to his comfort; for at length some poplars in a neighboring garden shot up to such a height as to obscure the tower, upon which Kant became very uneasy and restless, and at length found himself positively unable to pursue his evening meditations. Fortunately, the proprietor of the garden was a very considerate and obliging person, who had, besides, a high regard for Kant; and, accordingly, upon a representation of the case being made to him, he gave orders that the poplars should be cropped. This was done, the old tower of Lobenicht was again unveiled, and Kant recovered his equanimity, and pursued his twilight meditations as before.
After the candles were brought, Kant prosecuted his studies till nearly ten o'clock. A quarter of an hour before retiring for the night, he withdrew his mind as much as possible from every class of thoughts which demanded any exertion or energy of attention, on the principle, that by stimulating and exciting him too much, such thoughts would be apt to cause wakefulness; and the slightest interference with his customary hour of falling asleep, was in the highest degree unpleasant to him. Happily, this was with him a very rare occurrence. He undressed himself without his servant's assistance, but in such an order, and with such a Roman regard to decorum and the to prepon, that he was always ready at a moment's warning to make his appearance without embarrassment to himself or to others. This done, he lay down on a mattress, and wrapped himself up in a quilt, which in summer was always of cotton,—in autumn, of wool; at the setting-in of winter he used both—and against very severe cold, he protected himself by one of eider-down, of which the part which covered his shoulders was not stuffed with feathers, but padded, or rather wadded closely with layers of wool. Long practice had taught him a very dexterous mode of nesting himself, as it were, in the bed-clothes. First of all, he sat down on the bedside; then with an agile motion he vaulted obliquely into his lair; next he drew one corner of the bedclothes under his left shoulder, and passing it below his back, brought it round so as to rest under his right shoulder; fourthly, by a particular tour d'adresse, he treated the other corner in the same way, and finally contrived to roll it round his whole person. Thus swathed like a mummy, or (as I used to tell him) self-involved like the silk-worm in its cocoon, he awaited the approach of sleep, which generally came on immediately. For Kant's health was exquisite; not mere negative health, or the absence of pain, but a state of positive pleasurable sensation, and a genial sense of the entire possession of all his activities. Accordingly, when packed up for the night in the way I have described, he would often ejaculate to himself (as he used to tell us at dinner)— 'Is it possible to conceive a human being with more perfect health than myself?' In fact, such was the innocence of his life, and such the happy condition of his situation, that no uneasy passion ever arose to excite him—nor care to harass—nor pain to awake him. Even in the severest winter his sleeping-room was without a fire; only in his latter years he yielded so far to the entreaties of his friends as to allow of a very small one. All nursing or self-indulgence found no quarter with Kant. In fact, five minutes, in the coldest weather, sufficed to supersede the first chill of the bed, by the diffusion of a general glow over his person. If he had any occasion to leave his room in the night-time, (for it was always kept dark day and night, summer and winter,) he guided himself by a rope, which was duly attached to his bed-post every night, and carried into the adjoining apartment.
Kant never perspired, [Footnote: This appears less extraordinary, considering the description of Kant's person, given originally by Reichardt, about eight years after his death. 'Kant,' says this writer, 'was drier than dust both in body and mind. His person was small; and possibly a more meagre, arid, parched anatomy of a man, has not appeared upon this earth. The upper part of his face was grand; forehead lofty and serene, nose elegantly turned, eyes brilliant and penetrating; but below it expressed powerfully the coarsest sensuality, which in him displayed itself by immoderate addiction to eating and drinking.' This last feature of his temperament is here expressed much too harshly.] night or day. Yet it was astonishing how much heat he supported habitually in his study, and in fact was not easy if it wanted but one degree of this heat. Seventy-five degrees of Fahrenheit was the invariable temperature of this room in which he chiefly lived; and if it fell below that point, no matter at what season of the year, he had it raised artificially to the usual standard. In the heats of summer he went thinly dressed, and invariably in silk stockings; yet, as even this dress could not always secure him against perspiring when engaged in active exercise, he had a singular remedy in reserve. Retiring to some shady place, he stood still and motionless—with the air and attitude of a person listening, or in suspense—until his usual aridity was restored. Even in the most sultry summer night, if the slightest trace of perspiration had sullied his night-dress, he spoke of it with emphasis, as of an accident that perfectly shocked him.
On this occasion, whilst illustrating Kant's notions of the animal economy, it may be as well to add one other particular, which is, that for fear of obstructing the circulation of the blood, he never would wear garters; yet, as he found it difficult to keep up his stockings without them, he had invented for himself a most elaborate substitute, which I shall describe. In a little pocket, somewhat smaller than a watch-pocket, but occupying pretty nearly the same situation as a watch-pocket on each thigh, there was placed a small box, something like a watch-case, but smaller; into this box was introduced a watch- spring in a wheel, round about which wheel was wound an elastic cord, for regulating the force of which there was a separate contrivance. To the two ends of this cord were attached hooks, which hooks were carried through a small aperture in the pockets, and so passing down the inner and the outer side of the thigh, caught hold of two loops which were fixed on the off side and the near side of each stocking. As might be expected, so complex an apparatus was liable, like the Ptolemaic system of the heavens, to occasional derangements; however, by good luck, I was able to apply an easy remedy to these disorders which sometimes threatened to disturb the comfort, and even the serenity, of the great man.
Precisely at five minutes before five o'clock, winter or summer, Lampe, Kant's servant, who had formerly served in the army, marched into his master's room with the air of a sentinel on duty, and cried aloud in a military tone,—'Mr. Professor, the time is come.' This summons Kant invariably obeyed without one moment's delay, as a soldier does the word of command—never, under any circumstances, allowing himself a respite, not even under the rare accident of having passed a sleepless night. As the clock struck five, Kant was seated at the breakfast- table, where he drank what he called one cup of tea; and no doubt he thought it such; but the fact was, that in part from his habit of reverie, and in part also for the purpose of refreshing its warmth, he filled up his cup so often, that in general he is supposed to have drunk two, three, or some unknown number. Immediately after he smoked a pipe of tobacco, (the only one which he allowed himself through the entire day,) but so rapidly, that a pile of glowing embers remained unsmoked. During this operation he thought over his arrangements for the day, as he had done the evening before during the twilight. About seven he usually went to his lecture-room, and from that he returned to his writing-table. Precisely at three quarters before one he rose from his chair, and called aloud to the cook,—'It has struck three quarters.' The meaning of which summons was this:—Immediately after taking soup, it was his constant practice to swallow what he called a dram, which consisted either of Hungarian wine, of Rhenish, of a cordial, or (in default of these) of Bishop. A flask of this was brought up by the cook on the proclamation of the three quarters. Kant hurried with it to the eating-room, poured out his quantum, left it standing in readiness, covered, however, with paper, to prevent its becoming vapid, and then went back to his study, and awaited the arrival of his guests, whom to the latest period of his life he never received but in full dress.
Thus we come round again to dinner, and the reader has now an accurate picture of the course of Kant's day; the rigid monotony of which was not burthensome to him; and probably contributed, with the uniformity of his diet, and other habits of the same regularity, to lengthen his life. On this consideration, indeed, he had come to regard his health and his old age as in a great measure the product of his own exertions. He spoke of himself often under the figure of a gymnastic artist, who had continued for nearly fourscore years to support his balance upon the slack-rope of life, without once swerving to the right or to the left. In spite of every illness to which his constitutional tendencies had exposed him, he still kept his position in life triumphantly. However, he would sometimes observe sportively, that it was really absurd, and a sort of insult to the next generation for a man to live so long, because he thus interfered with the prospects of younger people.
This anxious attention to his health accounts for the great interest which he attached to all new discoveries in medicine, or to new ways of theorizing on the old ones. As a work of great pretension in both classes, he set the highest value upon the theory of the Scotch physician Brown, or (as it is usually called, from the Latin name of its author,) the Brunonian Theory. No sooner had Weikard adopted [Footnote: This theory was afterwards greatly modified in Germany; and, judging from the random glances which I throw on these subjects, I believe that in this recast it still keeps its ground in that country.] and made it known in Germany, than Kant became familiar with it. He considered it not only as a great step taken for medicine, but even for the general interests of man, and fancied that in this he saw something analogous to the course which human nature has held in still more important inquiries, viz.: first of all, a continual ascent towards the more and more elaborately complex, and then a treading back, on its own steps, towards the simple and elementary. Dr. Beddoes's Essays, also, for producing by art and curing pulmonary consumption, and the method of Reich for curing fevers, made a powerful impression upon him; which, however, declined as those novelties (especially the last) began to sink in credit. As to Dr. Jenner's discovery of vaccination, he was less favorably disposed to it; he apprehended dangerous consequences from the absorption of a brutal miasma into the human blood, or at least into the lymph; and at any rate he thought, that, as a guarantee against the variolous infection, it required a much longer probation. Groundless as all these views were, it was exceedingly entertaining to hear the fertility of argument and analogy which he brought forward to support them. One of the subjects which occupied him at the latter end of his life, was the theory and phenomena of galvanism, which, however, he never satisfactorily mastered. Augustin's book upon this subject was about the last that he read, and his copy still retains on the margin his, pencil-marks of doubts, queries and suggestions.
The infirmities of age now began to steal upon Kant, and betrayed themselves in more shapes than one. Connected with Kant's prodigious memory for all things that had any intellectual bearings, he had from youth labored under an unusual weakness of this faculty in relation to the common affairs of daily life. Some remarkable instances of this are on record, from the period of his childish days; and now, when his second childhood was commencing, this infirmity increased upon him very sensibly. One of the first signs was, that he began to repeat the same stories more than once on the same day. Indeed, the decay of his memory was too palpable to escape his own notice; and, to provide against it, and secure himself from all apprehension of inflicting tedium upon his guests, he began to write a syllabus, or list of themes, for each day's conversation, on cards, or the covers of letters, or any chance scrap of paper. But these memoranda accumulated so fast upon him, and were so easily lost, or not forthcoming at the proper moment, that I prevailed on him to substitute a blank-paper book, which I had directed to be made, and which still remains, with some affecting memorials of his own conscious weakness. As often happens, however, in such cases, he had a perfect memory for the remote events of his life, and could repeat with great readiness, and without once stumbling, very long passages from German or Latin poems, especially from the AEneid, whilst the very words that had been uttered but a moment before dropped away from his remembrance. The past came forward with the distinctness and liveliness of an immediate existence, whilst the present faded away into the obscurity of infinite distance.
Another sign of his mental decay was the weakness with which he now began to theorize. He accounted for everything by electricity. A singular mortality at this time prevailed amongst the cats of Vienna, Basle, Copenhagen, and other places. Cats being so eminently an electric animal, of course he attributed this epizootic to electricity. During the same period, he persuaded himself that a peculiar configuration of clouds prevailed; this he took as a collateral proof of his electrical hypothesis. His own headaches, too, which in all probability were a mere remote effect of old age, and a direct one of an inability [Footnote: Mr. Wasianski is quite in the wrong here. If the hindrances which nature presented to the act of thinking were now on the increase, on the other hand, the disposition to think, by his own acknowledgment, was on the wane. The power and the habit altering in proportion, there is no case made out of that disturbed equilibrium to which apparently he would attribute the headaches. But the fact is, that, if he had been as well acquainted with Kant's writings as with Kant personally, he would have known, that some affection of the head of a spasmodic kind was complained of by Kant at a time when nobody could suspect him of being in a decaying state.] to think as easily and as severely as formerly, he explained upon the same principle. And this was a notion of which his friends were not anxious to disabuse him, because, as something of the same character of weather (and therefore probably the same general tendency of the electric power) is found to prevail for whole cycles of years, entrance upon another cycle held out to him some prospect of relief. A delusion which secured the comforts of hope was the next best thing to an actual remedy; and a man who, in such circumstances, is cured of his delusion, 'cui demptus per vim mentis gratissimus error,' might reasonably have exclaimed, 'Pol, me occidistis, amici.'
Possibly the reader may suppose, that, in this particular instance of charging his own decays upon the state of the atmosphere, Kant was actuated by the weakness of vanity, or some unwillingness to face the real fact that his powers were decaying. But this was not the case. He was perfectly aware of his own condition, and, as early as 1799, he said, in my presence, to a party of his friends—'Gentlemen, I am old, and weak, and childish, and you must treat me as a child.' Or perhaps it may be thought that he shrank from the contemplation of death, which, as apoplexy seemed to be threatened by the pains in his head, might have happened any day. But neither was this the case. He now lived in a continual state of resignation, and prepared to meet any dispensation of Providence. 'Gentlemen,' said he one day to his guests, 'I do not fear to die. I assure you, as in the presence of God, that if I were this night to be made suddenly aware that I was on the point of being summoned, I would raise my hands to heaven, fold them, and say, Blessed be God! If indeed it were possible that a whisper such as this could reach my ear—Fourscore years thou hast lived, in which time thou hast inflicted much evil upon thy fellow-men, the case would be otherwise.' Whosoever has heard Kant speak of his own death, will bear witness to the tone of earnest sincerity which, on such occasions, marked his manner and utterance.
