Chapter XLI. The Astronomer Discovers the Cause of His Uneasiness
” I Suppose he discovered in me, through the obscurity of the room, some tokens of amazement and doubt, for, after a short pause, he proceeded thus :”
“Not to be easily credited will neither surprise nor offend me ; for I am, probably, the first of human beings to whom this trust has been imparted. Nor do I know whether to deem this distinction a reward or punishment ; since I have possessed it I have been far less happy  than before, and nothing but the consciousness of good intention could have enabled me to support the weariness of unremitted vigilance.”
” How long, Sir, said I, has this great office been in your hands?”
” About ten years ago, said he, my daily observations of the changes of the sky led me to confider, whether, if I had the power of the seasons, I could confer greater plenty upon the inhabitants of the earth. This contemplation fastened on my mind, and I sat days and nights in imaginary dominion, pouring upon this country and that the showers of fertility, and seconding every fall of rain with a due proportion of sunshine. I had yet only the will to do good,  and did not imagine that I should ever have the power.
” One day as I was looking on the fields withering with heat, I felt in my mind a sudden with that I could send rain on the southern mountains, and raise the Nile to an inundation. In the hurry of my imagination I commanded rain to fall, and, by comparing the time of, my command, with that of the inundation, I found that the clouds had listned to my lips.”
” Might not some other cause, said I, produce this concurrence? the Nile does not always rise on the fame day.”
” Do not believe, said he with impatience, that such objections could escape me ;  I reasoned long against my own convicion, and laboured against truth with the utmost obstinacy. I sometimes suspected myself of madness, and should not have dared to impart this secret but to a man like you, capable of distinguishing the wonderful from the impossible, and the incredible from the false.”
” Why, Sir, said I, do you call that incredible, which you know, or think you know, to be true?”
” Because, said he, I cannot prove it by any external evidence ; and I know too well the laws of demonstration to think that my conviction ought to influence another, who cannot, like me, be conscious of its force. I, therefore, shall not  attempt to gain credit by disputation. It is sufficient that I feel this power, that I have long possessed, and every day exerted it. But the life of man is short, the infirmities of age increase upon me, and the time will soon come when the regulator of the year must mingle with the dust. The care of appointing a successor has long disturbed me ; the night and the day have been spent in comparisons of all the characters which have come to my knowledge, and I have yet found none so worthy as thyself.
