The sublimer and more passionate poets I still read, as I have said, by snatches, and occasionally. But my proper vocation, as I well knew, was the exercise of the analytic understanding. Now, for the most part, analytic studies are continuous, and not to be pursued by fits and starts, or fragmentary efforts. Mathematics, for instance, intellectual philosophy, etc. were all become insupportable to me; I shrunk from them with a sense of powerless and infantine feebleness that gave me an anguish the greater from remembering the time when I grappled with them to my own hourly delight; and for this further reason, because I had devoted the labour of my whole life, and had dedicated my intellect, blossoms and fruits, to the slow and elaborate toil of constructing one single work, to which I had presumed to give the title of an unfinished work of Spinosa's, viz. De emendatione humani intellectûs. This was now lying locked up, as by frost, like any Spanish bridge or aqueduct, begun upon too great a scale for the resources of the architect; and, instead of surviving me as a monument of wishes at least, and aspirations, and a life of labour dedicated to the exaltation of human nature in that way in which God had best fitted me to promote so great an object, it was likely to stand a memorial to my children of hopes defeated, of baffled efforts, of materials uselessly accumulated, of foundations laid that were never to support a superstructure, – of the grief and the ruin of the architect. In this state of imbecility, I had, for amusement, turned my attention to political economy; my understanding, which formerly had been as active and restless as a hyena, could not, I suppose (so long as I lived at all) sink into utter lethargy; and political economy offers this advantage to a person in my state, that though it is eminently an organic science (no part, that is to say, but what acts on the whole, as the whole again reacts on each part), yet the several parts may be detached and contemplated singly. Great as was the prostration of my powers at this time, yet I could not forget my knowledge; and my understanding had been for too many years intimate with severe thinkers, with logic, and the great masters of knowledge, not to be aware of the utter feebleness of the main herd of modern economists. I had been led in 1811 to look into loads of books and pamphlets on many branches of economy; and, at my desire, M. sometimes read to me chapters from more recent works, or parts of parliamentary debates. I saw that these were generally the very dregs and rinsings of the human intellect; and that any man of sound head, and practised in wielding logic with a scholastic adroitness, might take up the whole academy of modern economists, and throttle them between heaven and earth with his finger and thumb, or bray their fungus heads to powder with a lady's fan. At length, in 1819, a friend in Edinburgh sent me down Mr. Ricardo's book: and recurring to my own prophetic anticipation of the advent of some legislator for his science, I said, before I had finished the first chapter, »Thou art the man!« Wonder and curiosity were emotions that had long been dead in me. Yet I wondered once more: I wondered at myself that I could once again be stimulated to the effort of reading: and much more I wondered at the book. Had this profound work been really written in England during the nineteenth century? Was it possible? I supposed thinking19 had been extinct in England. Could it be that an Englishman, and he not in academic bowers, but oppressed by mercantile and senatorial cares, had accomplished what all the universities of Europe, and a century of thought, had failed even to advance by one hair's breadth? All other writers had been crushed and overlaid by the enormous weight of facts and documents; Mr. Ricardo had deduced, à priori, from the understanding itself, laws which first gave a ray of light into the unwieldy chaos of materials, and had constructed what had been but a collection of tentative discussions into a science of regular proportions, now first standing on an eternal basis.

Thus did one single work of a profound understanding avail to give me a pleasure and an activity which I had not known for years: – it roused me even to write, or, at least, to dictate, what M. wrote for me. It seemed to me, that some important truths had escaped even ›the inevitable eye‹ of Mr. Ricardo: and, as these were, for the most part, of such a nature that I could express or illustrate them more briefly and elegantly by algebraic symbols than in the usual clumsy and loitering diction of economists, the whole would not have filled a pocket-book; and being so brief, with M. for my amanuensis, even at this time, incapable as I was of all general exertion, I drew up my Prolegomena to all future Systems of Political Economy. I hope it will not be found redolent of opium; though, indeed, to most people, the subject itself is a sufficient opiate.

This exertion, however, was but a temporary flash; as the sequel showed – for I designed to publish my work: arrangements were made at a provincial press, about eighteen miles distant, for printing it. An additional compositor was retained, for some days, on this account. The work was even twice advertised: and I was, in a manner, pledged to the fulfilment of my intention. But I had a preface to write; and a dedication, which I wished to make a splendid one, to Mr. Ricardo. I found myself quite unable to accomplish all this. The arrangements were countermanded: the compositor dismissed: and my »Prolegomena« rested peacefully by the side of its elder and more dignified brother.

I have thus described and illustrated my intellectual torpor, in terms that apply, more or less, to every part of the four years during which I was under the Circean spells of opium. But for misery and suffering, I might, indeed, be said to have existed in a dormant state.
