“Well, I daresay it looks absurd for a man at my years to be running after a moth. I used to think it was absurd, but I am wiser now. However, I cannot stop to talk; I shall lose the sunshine. The first time you are anywhere near me, come and have a look. You will alter your opinion.” Some weeks afterwards I happened to be in the neighbourhood of the butterfly-catcher’s house, and I called. He was at home, and welcomed me cordially. The first thing he did was to show me his little museum. It was really a wonderful exhibition, and as I saw the creatures in lines, and noted the amazing variations of the single type, I was filled with astonishment. Seeing the butterflies systematically arranged was a totally different thing from seeing a butterfly here and there, and gave rise to altogether new thoughts. My friend knew his subject from end to end, and I envied him his mastery of it. I had often craved the mastery of some one particular province, be it ever so minute. I half or a quarter knew a multitude of things, but no one thing thoroughly, and was never sure, just when I most wanted to be sure. We got into conversation, and I was urged to stay to dinner. I consented, and found that my friend’s household consisted of himself alone. After dinner, as we became a little more communicative, I asked him when and how he took to this pursuit. “It will be twenty-six years ago next Christmas,” said he, “since I suffered a great calamity. You will forgive my saying anything about it, as I have no assurance that the wound which looks healed may not break out again. Suffice to say, that for some ten years or more my thoughts were almost entirely occupied with death and our future state. There is a strange fascination about these topics to many people, because they are topics which permit a great deal of dreaming, but very little thinking: in fact, true thinking, in the proper sense of the word, is impossible in dealing with them. There is no rigorous advance from one position to another, which is really all that makes thinking worth the name. Every man can imagine or say cloudy things about death and the future, and feel himself here, at least, on a level with the ablest brain which he knows. “I went on gazing gloomily into dark emptiness, till all life became nothing for me. I did not care to live, because there was no assurance of existence beyond. By the strangest of processes, I neglected the world, because I had so short a time to be in it. It is with absolute horror now that I look back upon those days, when I lay as if alive in a coffin of lead. All passions and pursuits were nullified by the ever-abiding sense of mortality. For years this mood endured, and I was near being brought down to the very dust.
