which we can do it with the most effect, we shall very soon ‘go deep in the negative series.’ Take away the hope and the tendency to improvement, and there is nothing left to counteract the opposite never-failing tendency of human things ‘from bad to worse.’ There is therefore a serious practical reason against losing sight of the object, even when we cannot attain it. However, I am ‘free to confess’ (to borrow the language of my betters) that there is as much selfishness as public spirit in my resistance to Mr. Malthus’s contradictions. It is a remote question whether the world will ever be much wiser than it is: but what I am certainly interested in, is not to submit to have all my ideas confounded by barren sophistry, nor to give up the little understanding which I may actually possess. Nor for my own part, were I confined to my room, should I think myself obliged to any one for blocking up my view of a pleasant prospect, because I could not move from the place, where I was. The fundamental principle of Mr. Malthus’s essay is that population has a constant tendency to become excessive, because it has a tendency to increase not only in a progressive, but in a geometrical ratio, whereas the means of subsistence are either positively limited, or at most can only be made to increase in an arithmetical ratio. But to be sure of avoiding any thing like misrepresentation in this part of the argument, where the least error or omission might be fatal to our author’s whole scheme, let us take his own words. ‘It may be safely affirmed that population when unchecked goes on doubling itself every twenty-five years, or increases in a geometrical ratio. ‘That we may be the better able to compare the increase of population and food, let us make a supposition, which without pretending to accuracy, is clearly more favourable to the power of production in the earth, than any experience that we have had of its qualities will warrant. ‘Let us suppose that the yearly additions which might be made to the former average produce, instead of decreasing, which they certainly would do, were to remain the same; and that the produce of this island might be increased every twenty-five years by a quantity equal to what it at present produces; the most enthusiastic speculator cannot suppose a greater increase than this. In a few centuries it would make every acre of land in the island like a garden. ‘If this supposition be applied to the whole earth, and if it be allowed that the subsistence for man which the earth affords, might be increased every twenty-five years by a quantity equal to what it at present produces; this will be supposing a rate of increase much greater than we can imagine that any possible exertions of mankind could make it.
