A very poor English writer, whose works are all forgotten, and recognized as the most insignificant of the insignificant, writes a treatise on population, in which he devises a fictitious law concerning the increase of population disproportionate to the means of subsistence. This fictitious law, this writer encompasses with mathematical formulae founded on nothing whatever; and then he launches it on the world. From the frivolity and the stupidity of this hypothesis, one would suppose that it would not attract the attention of any one, and that it would sink into oblivion, like all the works of the same author which followed it; but it turned out quite otherwise. The hack-writer who penned this treatise instantly becomes a scientific authority, and maintains himself upon that height for nearly half a century. Malthus! The Malthusian theory,--the law of the increase of the population in geometrical, and of the means of subsistence in arithmetical proportion, and the wise and natural means of restricting the population,--all these have become scientific, indubitable truths, which have not been confirmed, but which have been employed as axioms, for the erection of false theories. In this manner have learned and cultivated people proceeded; and among the herd of idle persons, there sprung up a pious trust in the great laws expounded by Malthus. How did this come to pass? It would seem as though they were scientific deductions, which had nothing in common with the instincts of the masses. But this can only appear so for the man who believes that science, like the Church, is something self-contained, liable to no errors, and not simply the imaginings of weak and erring folk, who merely substitute the imposing word "science," in place of the thoughts and words of the people, for the sake of impressiveness.
All that was necessary was to make practical deductions from the theory of Malthus, in order to perceive that this theory was of the most human sort, with the best defined of objects. The deductions directly arising from this theory were the following: The wretched condition of the laboring classes was such in accordance with an unalterable law, which does not depend upon men; and, if any one is to blame in this matter, it is the hungry laboring classes themselves. Why are they such fools as to give birth to children, when they know that there will be nothing for the children to eat?
And so this deduction, which is valuable for the herd of idle people, has had this result: that all learned men overlooked the incorrectness, the utter arbitrariness of these deductions, and their insusceptibility to proof; and the throng of cultivated, i.e., of idle people, knowing instinctively to what these deductions lead, saluted this theory with enthusiasm, conferred upon it the stamp of truth, i.e., of science, and dragged it about with them for half a century.
Is not this same thing the cause of the confidence of men in positive critical-experimental science, and of the devout attitude of the crowd towards that which it preaches? At first it seems strange, that the theory of evolution can in any manner justify people in their evil ways; and it seems as though the scientific theory of evolution has to deal only with facts, and that it does nothing else but observe facts.
But this only appears to be the case.
Exactly the same thing appeared to be the case with the Hegelian doctrine, in a greater degree, and also in the special instance of the Malthusian doctrine. Hegelianism was, apparently, occupied only with its logical constructions, and bore no relation to the life of mankind. Precisely this seemed to be the case with the Malthusian theory. It appeared to be busy itself only with statistical data.
But this was only in appearance.
Contemporary science is also occupied with facts alone: it investigates facts. But what facts? Why precisely these facts, and no others?
