Now, if the population of a place in which the fecundity is less and the mortality greater than in other places still goes on increasing by propagation, it follows that in other places the population will increase, and increase still faster. There is clearly nothing in Mr. Sadler’s boasted law of fecundity which will keep the population from multiplying till the whole earth is as thick with human beings as St. Giles’s parish. If Mr. Sadler denies this, he must hold that, in places less thickly peopled than London, marriages may be less fruitful than in London, which is directly contrary to his own principles; or that in places less thickly peopled than London, and similarly situated, people will die faster than in London, which is again directly contrary {228}to his own principles. Now, if it follows, as it clearly does follow, from Mr. Sadler’s own doctrines, that the human race might he stowed together by three or four hundred to the acre, and might still, as far as the principle of propagation is concerned, go on increasing, what advantage, in a religious or moral point of view, has his theory over that of Mr. Malthus? The principle of Mr. Malthus, says Mr. Sadler, leads to consequences of the most frightful description. Be it so. But do not all these consequences spring equally from his own principle? Revealed religion condemns Mr. Malthus. Be it so. But Mr. Sadler must share in the reproach of heresy. The theory of Mr. Malthus represents the Deity as a Dionysius hanging the sword over the heads of his trembling slaves. Be it so. But under what rhetorical figure are we to represent the Deity of Mr. Sadler?
