A very commonplace English writer, whose books are now almost forgotten and recognized as the emptiest of all empty ones, wrote a tract upon population, in which he invented an imaginary law that the means of living do not increase with the increase of population. This sham law the author dressed out with the formulæ of mathematics which have no foundation whatever, and published it. Judged by the lightness of mind and the want of talent displayed in this treatise we might have supposed that it would have passed unnoticed and been forgotten as all other writings of the same author have been; but it turned out quite differently. The author who wrote it became at once a scientific authority, and has maintained this position for nearly half a century. Malthus! The Malthusian theory,--the law of the increase of population in geometrical progression, and the increase of means of living in arithmetical progression, and the natural and prudent means of restraining the increase of population,--all these became scientific, undoubted truths which have never been verified, but, accepted as axioms, have served for further deductions. Thus learned and educated men were deceived; whereas in the crowd of idle men there was a blind and religious trust in the great laws discovered by Malthus. How did this happen? These statements seem to be scientific deductions which have nothing in common with the instincts of the crowd. But they are only sacred to those who believe science to be something self-existent and infallible, like the Church, and not merely the thoughts of weak men liable to mistakes, who only for importance' sake call their own thoughts and words by a pompous word, _science_. It was only necessary to draw practical conclusions from the Malthusian theory in order to see that it was quite a human one with very determinate aims. The deductions which were directly drawn from this theory were the following: The miserable condition of working-people does not come from the cruelty, egotism, and unreasonableness of rich and powerful men, but it exists according to an unchangeable law which does not depend upon man, and, if anybody is to blame, it is the starving working-people themselves: why do these fools come into the world when they know that they will not have enough to eat? and therefore the wealthy and powerful classes are not at all to blame for any thing, and they may quietly continue to live as they have done. This conclusion, being pleasant to the crowd of idle men, induced the learned dons to overlook the incorrectness and total arbitrariness of the deductions; and the crowd of educated, i.e., idle people, instinctively guessing to what these deductions led, greeted the theory with delight, set upon it the seal of truth, and cherished it during half a century. The reason for all this was, that these doctrines justified men in their bad mode of life.
