"In after years Coleridge assured me that he never could read any thing he had written without a sense of overpowering disgust. Reverting to my own case, which was pretty nearly the same as this, there was, however, this difference--that at times, when I had slept at more regular hours for several nights consecutively, and had armed myself by a sudden increase of the opium for a few days running, I recovered at times a remarkable glow of jovial spirits. In some such artificial respites, it was, from my usual state of distress, and purchased at a heavy price of subsequent suffering, that I wrote the greater part of the opium 'Confessions' in the autumn of 1821.
"These circumstances I mention to account for my having written any thing in a happy or genial state of mind, when I was in a general state so opposite, by my own description, to every thing like enjoyment. That description, as a _general_ one, states most truly the unhappy condition, and the somewhat extraordinary condition of feeling to which opium had brought me. I, like Mr. Coleridge, could not endure what I had written for some time after I had written it. I also shrunk from treating any subject which I had much considered; but more, I believe, as recoiling from the intricacy and the elaborateness which had been made known to me in the course of considering it, and on account of the difficulty or the toilsomeness which might be fairly presumed from the mere fact that I _had_ long considered it, or could have found it necessary to do so, than from any blind mechanical feeling inevitably associated (as in Coleridge it was) with a second survey of the same subject. One other effect there was from the opium, and I believe it had some place in Coleridge's list of morbid affections caused by opium, and of disturbances extended even to the intellect, which was, that the judgment was for a time grievously impaired, sometimes even totally abolished, as applied to any thing I had recently written. Fresh from the labor of composition, I believe, indeed, that almost every man, unless he has had a very long and close experience in the practice of writing, finds himself a little dazzled and bewildered in computing the effect, as it will appear to neutral eyes, of what he has produced. But the incapacitation which I speak of here as due to opium, is of another kind and another degree. It is mere childish helplessness, or senile paralysis, of the judgment, which distresses the man in attempting to grasp the upshot and the total effect (the _tout ensemble_) of what he has himself so recently produced. There is the same imbecility in attempting to hold things steadily together, and to bring them under a comprehensive or unifying act of the judging faculty, as there is in the efforts of a drunken man to follow a chain of reasoning. Opium is said to have some _specific_ effect of debilitation upon the memory: [Footnote: The technical memory, or that which depends upon purely arbitrary links of connection, and therefore more upon a _nisus_ or separate activity of the mind--that memory, for instance, which recalls names--is undoubtedly affected, and most powerfully, by opium. On the other hand, the _logical_ memory, or that which recalls facts that are connected by fixed relations, and where A being given, B must go before or after--historical memory, for instance--is not much affected by opium.] that is, not merely the general one which might be supposed to accompany its morbid effects upon the bodily system, but some other, more direct, subtle, and exclusive; and this, of whatever nature, may possibly extend to the faculty of judging. Such, however, over and above the more known and more obvious ill effects upon fhe spirits and the health, were some of the stronger and more subtle effects of opium in disturbing the intellectual system as well as the animal, the functions of the will also no less than those of the intellect, from which both Coleridge and myself were suffering at the period to which I now refer (1821-25); evils which found their fullest exemplification in the very act upon which circumstances had now thrown me as the _sine qua non_ of my extrication from difficulties-- viz., the act of literary composition.
