much farther as it can, go. I should just reverse the reasoning of Mr. Malthus, who taking the evil as at its greatest height when the world is supposed to be completely full and completely enlightened, thence argues downwards against all attempts at improvement as dangerous innovations; so I, finding that an improved cultivation and enlarged population are good things through the inferior gradations, am apt to think they would continue so, proceeding upwards to the topmost round of the ladder, as far as population is concerned, for I once more give full and fair warning that I engage in this question no farther, any loose, general or accidental expressions to the contrary notwithstanding. To make good Mr. Malthus's argument against population, we must suppose, as I have said before, that the tendency in population to increase goes on increasing with the thing itself: this would be true, if as our author supposes in his first edition, the passion always required the same vent, in all circumstances, that is if we suppose man to be a mere headstrong animal in this respect, his reason having no influence whatever over his conduct, or which amounts to the same thing, that actual vice and misery (not foreseen, but felt) are the only checks to population. At this rate, it is evident that the degree of misery attending the

gratification of the passion would have no effect to restrain it, all degrees being alike indifferent or that the quantity of actual misery incurred would be in proportion to the increased power of producing it. I shall examine these positions more at large in another letter; I here wish to shew in a few words that as applied to the subject of increasing population, they lead to a direct absurdity. If we suppose this passion to be perfectly blind and insensible, to be deaf to all remonstrance, and regardless of all consequences, then no matter in what depths of misery it involves us, it will have its way, and go its own lengths. Take away the preventive check of moral restraint (which only comes in as a snivelling interpolation in some places of the second edition) and the population would no doubt go on doubling as fast as it could, not as fast as the means of subsistence would let it ; that is, the excess of population would be great in proportion to the actual previous increase, or the excessive multiplication of the species would be the necessary consequence of, and commensurate with the power of excessive multiplication, which would depend on the number of persons having that power. Now this is contrary to all we know of facts and human nature, since in this case there could be no restraint to population at any time, but the

extreme of vice or the extreme of misery. The power of population to increase is (we will grant) unlimited, but the tendency to increase is necessarily limited by its tendency to excess, and limited by it in proportion to the excess. That is to say, it does not follow that though when there ought to be only two millions of inhabitants, there may be four, owing to the weakness of the above-mentioned principle of moral restraint, that therefore that four (by the tendency of population to increase in a geometrical ratio or to double itself,) will in like manner become eight, and so on, namely because the checks to it will increase in proportion; or though the prospect of the inconveniences arising from doubling the population in the first instance, the quantity of food remaining the same, might not be sufficient to deter people, or overcome this propensity, yet the prospect of famine consequent upon the second doubling undoubtedly would, because their regard to consequences is supposed to remain the same, and the evils they have to dread in the one case are greater, and unless we suppose them to have become more stupid and brutal, must operate upon them more forcibly than in the other. The strength of the passion itself may be considered as always the same, or a given quantity: but the motives to resist it arising from the

consequences of its indulgence are not always the same, but may be either none at all, or very slight, or considerable, or extreme, as the obstacles to its indulgence may be either none at all, or a trifling inconvenience, or poverty, or absolute famine. Now the degree of excess in population, or the inconveniences to which we expose ourselves by inconsiderate gratification will depend entirely on the difference, be it more or less, between the strength of the passion in each individual, and the strength of moral restraint. If the latter principle is weak, it will require to be stimulated by the immediate apprehension of some very great inconvenience, before it will become a match for the importunity of physical desire. If it is strong, a general conviction of the propriety or prudence of selfdenial will be sufficient to incline the balance. But in no case unless we suppose man to be degraded to the condition of the brutes, will this principle be so low and weak as to have no effect at all, so that no apprehension of the last degree of wretchedness, as the consequence, would take off or abate the edge of appetite. There is therefore always a point at which the excess ceases, and we have seen what this point at all times is. Thus if the operation of rational motives is so much upon a level with the physical impulse, as to keep population exactly

or nearly down to the means of subsistence, it will do so equally whether that population is actually greater or less, whether it is stationary or progressive, for it will increase only with the means by which it is supported. On the other hand if from the manners, the habits, and institutions of society, there is a considerable tendency in population to excess, this tendency to excess will not be greater or less in proportion to the actual number of inhabitants, or the actual quantity of food, nor will it depend on their being progressive or stationary, but on the morals of the people being retrograde, progressive, or stationary; for the tendency of population itself to excess or to increase excessively (a dubious kind of expression) is not a perpetual, indefinite, invariable tendency to increase from 2 to 4, from 4 to 8, &c. (as I have just shewn) but a tendency to increase beyond the means of subsistence to a certain point or degree. This tendency to excess will consequently be the sime wherever we fix the point of subsistence, because it is only a given tendency to outstrip that limit whether nearer or farther off, whether advancing or retreating. It is true there is a

* I here leave out of the question, as not essential to it, the effect of sudden rises or falls, and other accidental variations in the produce of a country which cannot be foreseen or provided against, on the state of population.
