These unseasonable dozings exposed him to another danger. He fell repeatedly, whilst reading, with his head into the candles; a cotton night-cap which he wore was instantly in a blaze, and flaming about his head. Whenever this happened, Kant behaved with great presence of mind. Disregarding the pain, he seized the blazing cap, drew it from his head, laid it quietly on the floor, and trod out the flames with his feet. Yet, as this last act brought his dressing-gown into a dangerous neighborhood to the flames, I changed the form of his cap, persuaded him to arrange the candles differently, and had a decanter of water placed constantly by his side; and in this way I applied a remedy to a danger, which would else probably have been fatal to him. From the sallies of impatience, which I have described in the case of the coffee, there was reason to fear that, with the increasing infirmities of Kant, would grow up a general waywardness and obstinacy of temper. For my own sake, therefore, and not less for his, I now laid down one rule for my future conduct in his house; which was, that I would, on no occasion, allow my reverence for him to interfere with the firmest expression of my opinion on subjects relating to his own health; and in cases of great importance, that I would make no compromise with his particular humors, but insist, not only on my view of the case, but also on the practical adoption of my views; or, if this were refused me, that I would take my departure at once, and not be made responsible for the comfort of a person whom I had no power to influence. And this behavior on my part it was that won Kant's confidence; for there was nothing which disgusted him so much as any approach to fawning or sycophancy. As his imbecility increased, he became daily more liable to mental delusions; and, in particular, he fell into many fantastic notions about the conduct of his servants, and, in consequence, into a peevish mode of treating them. Upon these occasions I generally observed a deep silence. But sometimes he would ask me for my opinion; and when this happened, I did not scruple to say, 'Ingenuously, then, Mr. Professor, I think that you are in the wrong.'--'You think so?' he would reply calmly, at the same time asking for my reasons, which he would listen to with great patience, and openness to conviction. Indeed, it was evident that the firmest opposition, so long as it rested upon assignable grounds and principles, won upon his regard; whilst his own nobleness of character still moved him to habitual contempt for timorous and partial acquiescence in his opinions, even when his infirmities made him most anxious for such acquiescence.
