The Miscellaneous Writings and Speeches-2 [80]
Is it an experience which includes experience of the conduct of men intrusted with the powers of government; or is it exclusive of that experience? If it includes experience of the manner in which men act when intrusted with the powers of government, then those principles of human nature from which the science of government is to be deduced can only be known after going through that inductive process by which we propose to arrive at the science of government. Our knowledge of human nature, instead of being prior in order to our knowledge of the science of government, will be posterior to it. And it would be correct to say, that by means of the science of government, and of other kindred sciences--the science of education, for example, which falls under exactly the same principle--we arrive at the science of human nature. If, on the other hand, we are to deduce the theory of government from principles of human nature, in arriving at which principles we have not taken into the account the manner in which men act when invested with the powers of government, then those principles must be defective. They have not been formed by a sufficiently copious induction. We are reasoning, from what a man does in one situation, to what he will do in another. Sometimes we may be quite justified in reasoning thus. When we have no means of acquiring information about the particular case before us, we are compelled to resort to cases which bear some resemblance to it. But the more satisfactory course is to obtain information about the particular case; and, whenever this can be obtained, it ought to be obtained. When first the yellow fever broke out, a physician might be justified in treating it as he had been accustomed to treat those complaints which, on the whole, had the most symptoms in common with it. But what should we think of a physician who should now tell us that he deduced his treatment of yellow fever from the general theory of pathology? Surely we should ask him, Whether, in constructing his theory of pathology, he had or had not taken into the account the facts which had been ascertained respecting the yellow fever? If he had, then it would be more correct to say that he had arrived at the principles of pathology partly by his experience of cases of yellow fever than that he had deduced his treatment of yellow fever from the principles of pathology. If he had not, he should not prescribe for us. If we had the yellow fever, we should prefer a man who had never treated any cases but cases of yellow fever to a man who had walked the hospitals of London and Paris for years, but who knew nothing of our particular disease. Let Lord Bacon speak for us: "Inductionem censemus eam esse demonstrandi formam, quae sensum tuetur, et naturam premit, et operibus imminet, ac fere immiscetur. Itaque ordo quoque demonstrandi plane invertitur. Adhuc enim res ita geri consuevit, ut a sensu et particularibus primo loco ad maxime generalia advoletur, tanquam ad polos fixos, circa quos disputationes vertantur; ab illis caetera, per media, deriventur; via certe compendiaria, sed praecipiti, et ad naturam impervia, ad disputationes proclivi et accommodata. At, secundum nos, axiomata continenter et gradatim excitantur, ut non, nisi postremo loco, ad maxime generalia veniatur." Can any words more exactly describe the political reasonings of Mr Mill than those in which Lord Bacon thus describes the logomachies of the schoolmen? Mr Mill springs at once to a general principle of the widest extent, and from that general principle deduces syllogistically every thing which is included in it. We say with Bacon--"non, nisi postremo loco, ad maxime generalia veniatur." In the present inquiry, the science of human nature is the "maxime generale." To this the Utilitarian rushes at once, and from this he deduces a hundred sciences. But the true philosopher, the inductive reasoner, travels up to it slowly, through those hundred sciences, of which the science of government is one. As we have lying before us that incomparable volume, the noblest
