[Footnote 26: In a slight article on Mr. Malthus, lately published, I omitted to take any notice of the recent controversy between this gentleman--Mr. Godwin--and Mr. Booth; my reason for which was--that I have not yet found time to read it. But, if Mr. Lowe has rightly represented this principle of Mr. Booth's argument in his late work on the Statistics of England, it is a most erroneous one: for Mr. Booth is there described as alleging against Mr. Malthus that, in his view of the tendencies of the principle of population, he has relied too much on the case of the United States--which Mr. Booth will have to be an extreme case, and not according to the general rule. But of what consequence is this to Mr. Malthus? And how is he interested in relying on the case of America rather than that of the oldest European country? Because he assumes a perpetual nisus in the principle of human increase to pass a certain limit, he does not therefore hold that this limit ever _is_ passed either in the new countries or in old (or only for a moment, and inevitably to be thrown back within it). Let this limit be placed where it may, it can no more be passed in America than in Europe; and America is not at all more favourable to Mr. Malthus's theory than Europe. Births, it must be remembered, are more in excess in Europe than in America: though they do not make so much positive addition to the population.] 'Avoid, old Satanas!' I exclaim, if any man attempts to fling dust in my eyes by false syllogism, or any mode of dialectic sophism. And in relation to this particular subject of value, I flatter myself that in a paper expressly applied to the exposure of Mr. Malthus's blunders in his Political Economy, I have made it impossible for Mr. Malthus, even though he should take to his assistance seven worse logicians than himself, to put down my light with their darkness. Meantime, as a labour of shorter compass, I will call the reader's attention to the following blunder, in a later work of Mr. Malthus's--viz. a pamphlet of eighty pages, entitled, _The Measure of Value, stated and applied_ (published in the spring of the present year). The question proposed in this work is the same as that already discussed in his Political Economy--viz. What is the measure of value? But the answer to it is different: in the Political Economy, the measure of value was determined to be a mean between corn and labour; in this pamphlet, Mr. Malthus retracts that opinion, and (finally, let us hope) settles it to his own satisfaction that the true measure is labour; not the quantity of labour, observe, which will produce X, but the quantity which X will command. Upon these two answers, and the delusions which lie at their root, I shall here forbear to comment; because I am now chasing Mr. Malthus's _logical_ blunders; and these delusions are not so much logical as economic: what I now wish the reader to attend to--is the blunder involved in the question itself; because that
