"You have a strange taste," replied Ernstein, not altogether well pleased, in the first instance, at the explanation of his companion's feelings. A moment's reflection, however, convinced him that there was some affectation in the account, but that the affectation was of that generous kind which seeks to diminish the value of an obligation conferred upon another, even at the risk of appearing hard or selfish. "Well," he continued, "your motives are your own affairs; but the kindness you have shown me is mine, and I must feel gratitude accordingly." While they were still speaking, the surgeon again entered, and his appearance put a stop to the conversation for the night. On the following morning, however, the patient was so far better as to be permitted to rise for a short time, and his fellow-traveller visited him towards the middle of the day, announcing that he came to bid him farewell, as he had just received letters which summoned him to London. "I do not go unwillingly," he continued, "for my plan of life is ever to hasten forward. Existence is so short that we have no time for long pauses anywhere; each joy of each period--each thought, each feeling of each period of animal being should be tasted, or they will be lost, for we must never forget the great axiom, that every minute we are a minute older." "But do you not think," said Morley, "that we may sometimes, in our haste, taste a bitter instead of a sweet?" "So much the better--so much the better," replied his friend, laughing; "it is by such things that we become wise. I am quite of the opinion of your great poet, Coleridge, that-- 'The strongest plume in Wisdom's wing Is memory of past folly;' and depend upon it every man will find in life, that to be very wise, he must be a little foolish. The child that does not cut its finger before it is eight years old, will cut its hand by the time it is twelve, and perhaps its throat by the time it is twenty. What I mean is--for I see you are surprised--that we must learn what is evil or dangerous, by that acquaintance with evil and danger which is fitted for our time of life, otherwise we are sure to get our portion all at once, at some after period. It is like one of those medicines which doctors tell us accumulate in the system, and kill us suddenly when we least expect it; or rather, like one of those Eastern drugs, which are very salutary when we take a little of them every day, but utterly poisonous if we take a large dose at once." "Might it not be better for a healthy person to take none at all?" demanded Morley; and added, the moment after, seeing his companion about to reply, "but I am not fit to argue to-day, though I think that your system has some flaws in it."
