An Essay on the Principle of Population
By Thomas Robert Malthus
There are two versions of Thomas Robert Malthus’s
Essay on the Principle of Population. The first, published anonymously in 1798, was so successful that Malthus soon elaborated on it under his real name.
* The rewrite, culminating in the sixth edition of 1826, was a scholarly expansion and generalization of the first.Following his success with his work on population, Malthus published often from his economics position on the faculty at the East India College at Haileybury. He was not only respected in his time by contemporaneous intellectuals for his clarity of thought and willingness to focus on the evidence at hand, but he was also an engaging writer capable of presenting logical and mathematical concepts succinctly and clearly. In addition to writing principles texts and articles on timely topics such as the corn laws, he wrote in many venues summarizing his initial works on population, including a summary essay in the
Encyclopædia Britannica on population.The first and sixth editions are presented on Econlib in full. Minor corrections of punctuation, obvious spelling errors, and some footnote clarifications are the only substantive changes.* Malthus’s “real name” may have been Thomas Robert Malthus, but a descendent, Nigel Malthus, reports that his family says he did not use the name Thomas and was known to friends and colleagues as Bob.

Chapter XIV
Mr. Godwin’s five propositions respecting political truth, on which his whole work hinges, not established—Reasons we have for supposing, from the distress occasioned by the principle of population, that the vices and moral weakness of man can never be wholly eradicated—Perfectibility, in the sense in which Mr. Godwin uses the term, not applicable to man—Nature of the real perfectibility of man illustrated.
If the reasonings of the preceding chapter are just, the corollaries respecting political truth, which Mr. Godwin draws from the proposition, that the voluntary actions of men originate in their opinions, will not appear to be clearly established. These corollaries are, “Sound reasoning and truth, when adequately communicated, must always be victorious over error: Sound reasoning and truth are capable of being so communicated: Truth is omnipotent: The vices and moral weakness of man are not invincible: Man is perfectible, or in other words, susceptible of perpetual improvement.”
The first three propositions may be considered a complete syllogism. If by adequately communicated, be meant such a conviction as to produce an adequate effect upon the conduct; the major may be allowed and the minor denied. The consequent, or the omnipotence of truth, of course falls to the ground. If by adequately communicated be meant merely the conviction of the rational faculty; the major must be denied, the minor will be only true in cases capable of demonstration, and the consequent equally falls. The fourth proposition, Mr. Godwin calls the preceding proposition, with a slight variation in the statement. If so, it must accompany the preceding proposition in its fall. But it may be worth while to inquire, with reference to the principal argument of this essay, into the particular reasons which we have for supposing, that the vices and moral weakness of man can never be wholly overcome in this world.
Man, according to Mr. Godwin, is a creature, formed what he is, by the successive impressions which he has received, from the first moment that the germ from which he sprung was animated. Could he be placed in a situation, where he was subject to no evil impressions whatever, though it might be doubted whether in such a situation virtue could exist, vice would certainly be banished. The great bent of Mr. Godwin’s work on political justice, if I understand it rightly, is to shew that the greater part of the vices and weaknesses of men, proceed from the injustice of their political and social institutions: and that if these were removed, and the understandings of men more enlightened, there would be little or no temptation in the world to evil. As it has been clearly proved, however, (at least as I think) that this is entirely a false conception, and that, independent of any political or social institutions whatever, the greater part of mankind, from the fixed and unalterable laws of nature, must ever be subject to the evil temptations arising from want, besides other passions; it follows from Mr. Godwin’s definition of man, that such impressions, and combinations of impressions, cannot be afloat in the world, without generating a variety of bad men. According to Mr. Godwin’s own conception of the formation of character, it is surely as improbable that under such circumstances, all men will be virtuous, as that sixes will come up a hundred times following upon the dice. The great variety of combinations upon the dice in a repeated succession of throws, appears to me not inaptly to represent the great variety of character that must necessarily exist in the world, supposing every individual to be formed what he is, by that combination of impressions which he has received since his first existence. And this comparison will, in some measure, shew the absurdity of supposing, that exceptions will ever become general rules; that extraordinary and unusual combinations will be frequent; or that the individual instances of great virtue which had appeared in all ages of the world will ever prevail universally.
I am aware that Mr. Godwin might say that the comparison is in one respect inaccurate; that in the case of the dice, the preceding causes, or rather the chances respecting the preceding causes, were always the same; and that, therefore, I could have no good reason for supposing that a greater number of sixes would come up in the next hundred times of throwing, than in the preceding same number of throws. But, that man had in some sort a power of influencing those causes that formed character; and that every good and virtuous man that was produced, by the influence which he must necessarily have, rather increased the probability that another such virtuous character would be generated; whereas the coming up of sixes upon the dice once, would certainly not increase the probability of their coming up a second time. I admit this objection to the accuracy of the comparison, but it is only partially valid. Repeated experience has assured us, that the influence of the most virtuous character will rarely prevail against very strong temptations to evil. It will undoubtedly affect some, but it will fail with a much greater number. Had Mr. Godwin succeeded in his attempt to prove that these temptations to evil could by the exertions of man be removed, I would give up the comparison; or at least allow, that a man might be so far enlightened with regard to the mode of shaking his elbow, that he would be able to throw sixes every time. But as long as a great number of those impressions which form character, like the nice motions of the arm, remain absolutely independent of the will of man; though it would be the height of folly and presumption, to attempt to calculate the relative proportions of virtue and vice at the future periods of the world; it may be safely asserted, that the vices and moral weakness of mankind, taken in the mass, are invincible.
The fifth proposition, is the general deduction from the four Former, and will consequently fall, as the foundations which support it have given way. In the sense in which Mr. Godwin understands the term perfectible, the perfectibility of man cannot be asserted, unless the preceding propositions could have been clearly established. There is, however, one sense, which the term will bear, in which it is, perhaps, just. It may be said with truth, that man is always susceptible of improvement; or that there never has been, or will be, a period of his history, in which he can be said to have reached his possible achmè of perfection. Yet it does not by any means follow from this, that our efforts to improve man will always succeed; or even that he will ever make, in the greatest number of ages, any extraordinary strides towards perfection. The only inference that can be drawn, is, that the precise limit of his improvement cannot possibly be known. And I cannot help again reminding the reader of a distinction, which, it appears to me, ought particularly to be attended to in the present question; I mean, the essential difference there is between an unlimited improvement, and an improvement the limit of which cannot be ascertained. The former is an improvement not applicable to man under the present laws of his nature. The latter, undoubtedly, is applicable.
The real perfectibility of man may be illustrated, as I have mentioned before, by the perfectibility of a plant. The object of the enterprizing florist is, as I conceive, to unite size, symmetry, and beauty of colour. It would surely be presumptuous in the most successful improver to affirm, that he possessed a carnation in which these qualities existed in the greatest possible state of perfection. However beautiful his flower may be, other care, other soil, or other suns, might produce one still more beautiful. Yet, although he may be aware of the absurdity of supposing that he has reached perfection; and though he may know by what means he attained that degree of beauty in the flower which he at present possesses, yet he cannot be sure that by pursuing similar means, rather increased in strength, he will obtain a more beautiful blossom. By endeavouring to improve one quality, he may impair the beauty of another. The richer mould which he would employ to increase the size of his plant, would probably burst the calyx, and destroy at once its symmetry. In a similar manner, the forcing manure used to bring about the French revolution, and to give a greater freedom and energy to the human mind, has burst the calyx of humanity, the restraining bond of all society; and, however large the separate petals have grown, however strongly, or even beautifully a few of them have been marked; the whole is at present a loose, deformed, disjointed mass, without union, symmetry, or harmony of colouring.
Were it of consequence to improve pinks and carnations, though we could have no hope of raising them as large as cabbages, we might undoubtedly expect, by successive efforts, to obtain more beautiful specimens than we at present possess. No person can deny the importance of improving the happiness of the human species. Every, the least advance in this respect, is highly valuable. But an experiment with the human race is not like an experiment upon inanimate objects. The bursting of a flower may be a trifle. Another will soon succeed it. But the bursting of the bonds of society is such a separation of parts as cannot take place without giving the most acute pain to thousands: and a long time may elapse, and much misery may be endured, before the wound grows up again.
As the five propositions which I have been examining may be considered as the corner stones of Mr. Godwin’s fanciful structure; and, indeed, as expressing the aim and bent of his whole work; however excellent much of his detached reasoning may be, he must be considered as having failed in the great object of his undertaking. Besides the difficulties arising from the compound nature of man, which he has by no means sufficiently smoothed; the principal argument against the perfectibility of man and society remains whole and unimpaired from any thing that he has advanced. And as far as I can trust my own judgement, this argument appears to be conclusive, not only against the perfectibility of man, in the enlarged sense in which Mr. Godwin understands the term, but against any very marked and striking change for the better, in the form and structure of general society; by which I mean, any great and decided amelioration of the condition of the lower classes of mankind, the most numerous, and, consequently, in a general view of the subject, the most important part of the human race. Were I to live a thousand years, and the laws of nature to remain the same, I should little fear, or rather little hope, a contradiction from experience, in asserting, that no possible sacrifices or exertions of the rich, in a country which had been long inhabited, could for any time place the lower classes of the community in a situation equal, with regard to circumstances, to the situation of the common people about thirty years ago in the northern States of America.
The lower classes of people in Europe may, at some future Period, be much better instructed than they are at present; they may be taught to employ the little spare time they have in many better ways than at the ale-house; they may live under better and more equal laws than they have ever hitherto done, perhaps, in any country; and I even conceive it possible, though not probable, that they may have more leisure; but it is not in the nature of things, that they can be awarded such a quantity of money or subsistence as will allow them all to marry early, in the full confidence that they shall be able to provide with ease for a numerous family.
