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.

A third sign of his decaying faculties was, that he now lost all accurate measure of time. One minute, nay, without exaggeration, a much less space of time, stretched out in his apprehension of things to a wearisome duration. Of this I can give one rather amusing instance, which was of constant recurrence. At the beginning of the last year of his life, he fell into a custom of taking immediately after dinner a cup of coffee, especially on those days when it happened that I was of his party. And such was the importance he attached to this little pleasure, that he would even make a memorandum beforehand, in the blank-paper book I had given him, that on the next day I was to dine with him, and consequently that there was to be coffee. Sometimes it would happen, that the interest of conversation carried him past the time at which he felt the craving for it; and this I was not sorry to observe, as I feared that coffee, which he had never been accustomed to, [Footnote: How this happened to be the case in Germany, Mr. Wasianski has not explained. Perhaps the English merchants at Koenigsberg, being amongst Kant’s oldest and most intimate friends, had early familiarized him to the practice of drinking tea, and to other English tastes. However, Jachmann tells us, (p. 164,) that Kant was extravagantly fond of coffee, but forced himself to abstain from it under a notion that it was very unwholesome.] might disturb his rest at night. But, if this did not happen, then commenced a scene of some interest. Coffee must be brought ‘upon the spot,’ (a word he had constantly in his mouth during his latter days,) ‘in a moment.’ And the expressions of his impatience, though from old habit still gentle, were so lively, and had so much of infantine naivete about them, that none of us could forbear smiling. Knowing what would happen, I had taken care that all the preparations should be made beforehand; the coffee was ground; the water was boiling; and the very moment the word was given, his servant shot in like an arrow, and plunged the coffee into the water. All that remained, therefore, was to give it time to boil up. But this trifling delay seemed unendurable to Kant. All consolations were thrown away upon him: vary the formula as we might, he was never at a loss for a reply. If it was said–‘Dear Professor, the coffee will be brought up in a moment.’–‘Will be!’ he would say, ‘but there’s the rub, that it only will be:
