I conceive there were two very capital errors in Mr. Malthus’s first essay, which though he has abandoned or in a great measure softened them down in his subsequent edition, still adhere to all his reasonings, and give them a wrong bias. The first of these was, that vice and misery are the only checks to population: secondly, that if population were for any time freed from these restraints, it would in that case go on increasing with a force and rapidity, which nothing would be able to withstand, and which would bear down the feeble mounds that had before opposed its progress till the whole would end in one wide scene of universal uproar and confusion. As if, in the first place, mere misery of itself, without a sense of greater misery, and a desire to avoid it, would do any thing to prevent population; and in the second place, as if though the tax of vice and misery were taken off for a time, yet the recurrence of the same evils afterwards would not operate in the same way to repress population, or as if population would in the mean time have acquired any preternatural strength, with which its counteracting causes would be unable to contend, or as if the mere mechanical checks to population from the actual evils attendant upon it were not always necessarily a match for, and proportioned to, the strength of the principle itself, and its immediate tendency to excess. It is astonishing to see how those men, who pique themselves the most on the solidity of their understandings, and on a kind of dull matter-of-fact plodding accuracy, are perpetually led away by their imaginations: the more so because they are the dupes of their own vanity, and never suspect that they are liable to any such deception. In the present instance our author has been hurried into an unfounded assumption by having his imagination heated with a _personification_. He has given to the principle of population a personal existence, conceiving of it as a sort of infant Hercules, as one of that terrific giant brood, which you can only master by strangling it in its cradle; forgetting that the antagonist principle which he has made its direct counterpoise, still grows with its growth and strengthens with its strength, being in fact its own offspring: and that the sharper evils which excessive population brings along with it, more severe in proportion to its excess, naturally tend to repress and keep population down to the same level, other circumstances being supposed the same. Nothing can be clearer to my understanding than this; yet it is upon the misrepresentation or misconception of this principle that most of Mr. Malthus’s sophisms and ambiguities hinge.
