"It was in the autumn of 1826. I was in a dull state of nerves, such as everybody is occasionally liable to; unsusceptible to enjoyment or pleasurable excitement; one of those moods when what is pleasure at other times, becomes insipid or indifferent; the state, I should think, in which converts to Methodism usually are, when smitten by their first "conviction of sin." In this frame of mind it occurred to me to put the question directly to myself: "Suppose that all your objects in life were realized; that all the changes in institutions and opinions which you are looking forward to, could be completely effected at this very instant: would this be a great joy and happiness to you?" And an irrepressible self-consciousness distinctly answered, "No!" At this my heart sank within me: the whole foundation on which my life was constructed fell down. All my happiness was to have been found in the continual pursuit of this end. The end had ceased to charm, and how could there ever again be any interest in the means? I seemed to have nothing left to live for.
At first I hoped that the cloud would pass away of itself; but it did not. A night's sleep, the sovereign remedy for the smaller vexations of life, had no effect on it. I awoke to a renewed consciousness of the woful fact. I carried it with me into all companies, into all occupations. Hardly anything had power to cause me even a few minutes oblivion of it. For some months the cloud seemed to grow thicker and thicker. The lines in Coleridge's "Dejection" -- I was not then acquainted with them -- exactly describe my case:
"A grief without a pang, void, dark and drear, A drowsy, stifled, unimpassioned grief, Which finds no natural outlet or relief In word, or sigh, or tear."In vain I sought relief from my favourite books; those memorials of past nobleness and greatness from which I had always hitherto drawn strength and animation. I read them now without feeling, or with the accustomed feeling minus all its charm; and I became persuaded, that my love of mankind, and of excellence for its own sake, had worn itself out. I sought no comfort by speaking to others of what I felt. If I had loved any one sufficiently to make confiding my griefs a necessity, I should not have been in the condition I was. I felt, too, that mine was not an interesting, or in any way respectable distress. There was nothing in it to attract sympathy. Advice, if I had known where to seek it, would have been most precious...
I was thus, as I said to myself, left stranded at the commencement of my voyage, with a well-equipped ship and a rudder, but no sail; without any real desire for the ends which I had been so carefully fitted out to work for: no delight in virtue, or the general good, but also just as little in anything else. The fountains of vanity and ambition seemed to have dried up within me, as completely as those of benevolence. I had had (as I reflected) some gratification of vanity at too early an age: I had obtained some distinction, and felt myself of some importance, before the desire of distinction and of importance had grown into a passion: and little as it was which I had attained, yet having been attained too early, like all pleasures enjoyed too soon, it had made me blasé and indifferent to the pursuit. Thus neither selfish nor unselfish pleasures were pleasures to me. And there seemed no power in nature sufficient to begin the formation of my character anew..."
