the author, that is to say, one in which abstract reason and pure virtue, or a regard to the general good, should have got the better of every animal instinct and selfish passion. Of this, perhaps, a word hereafter. But be this as it may, both the principle of the necessary increase of the population beyond the means of subsistence, and the application of that principle as a final obstacle to all Utopian perfectibility schemes, are borrowed (whole) by Mr. Malthus from Wallace's work. This is not very stoutly denied by his admirers; but, say they, Mr. Malthus was the first to reduce the inequality between the possible increase of food and population to a mathematical certainty, to the arithmetical and geometrical ratios. In answer to which, we say, that those ratios are, in a strict and scientific view of the subject, entirely fallacious—a pure fiction. For a grain of corn or of mustard-seed has the same or a greater power of propagating its species than a man, till it has overspread the whole earth, till there is no longer any room for it to grow or to spread farther. A bushel of wheat will sow a whole field: the produce of that field will sow twenty fields, and produce twenty harvests. Till there are no longer fields to sow, that is, till a country or the earth is exhausted, the means of subsistence will go on increasing in more than a geometrical ratio; will more than double itself in every generation or season, and will more than keep pace with the progress of population; for this is supposed only to double itself, where it is unchecked, every twenty years. Therefore it is not true as an abstract proposition, that of itself, or in the nature of the growth of the produce of the earth, food can only increase in the snail-pace progress of an arithmetical ratio, while population goes on at a swinging geometrical rate: for the food keeps pace, or more than keeps pace, with the population, while there is room to grow it in, and after that room is filled up, it does not go on, even in that arithmetical ratio—it does not increase at all, or very little. That is, the ratio, instead of being always true, is never true at all: neither before the soil is fully cultivated, nor afterwards. Food does not
