All attempts by the State to bias the conclusions of its citizens on disputed subjects, are evil; but it may very properly offer to ascertain and certify that a person possesses the knowledge, requisite to make his conclusions, on any given subject, worth attending to.
I have reserved for the last place a large class of questions respecting the limits of government interference, (in education). The objections to government interference, when it is not such as to involve infringement of liberty, may be of three kinds.
The first is, when the thing to be done is likely to be better done by individuals than by the government. Speaking generally, there is no one so fit to conduct any business, or to determine how or by whom it shall he conducted, as those who are personally interested in it.
This principle condemns the interferences of the legislature, or the officers of government, with the ordinary processes of industry.
The second objection is more nearly allied to our subject. In many cases, though individuals may not do the particular thing so well, on the average, as the officers of government, it is nevertheless desirable that it should be done by them, rather than by the government, as a means to their own mental education—a mode of strengthening their active faculties, exercising their judgment, and giving them a familiar knowledge of the subjects with which they are thus left to deal.
These are not questions of liberty, and are connected with that subject only by remote tendencies; but they are questions of development. It belongs to a different occasion from the present to dwell on these things as parts of national education; as being, in truth, the peculiar training of a citizen, the practical part of the political education of a free people, taking them out of the narrow circle of personal and family selfishness, and accustoming them to the comprehension of joint interests, the management of joint concerns—habituating them to act from public or semi-public motives, and guide their conduct by aims which unite instead of isolating them from one another.
Without these habits and powers, a free constitution can neither be worked nor preserved; as is exemplified by the too-often transitory nature of political freedom in countries where it does not rest upon a sufficient basis of local liberties. The management of purely local business by the localities, and of the great enterprises of industry by the union of those who voluntarily supply the pecuniary means, is further recommended by all the advantages which have been set forth in this Essay as belonging to individuality of development, and diversity of modes of action.
Government operations tend to be everywhere alike.
With individuals and voluntary associations, on the contrary, there are varied experiments, and endless diversity of experience. What the State can usefully do is to make itself a central depository, and active circulator and diffuser, of the experience resulting from many trials. Its business is to enable each experimentalist to benefit by the experiments of others; instead of tolerating no experiments but its own.
The third, and most cogent reason for restricting the interference of government, is the great evil of adding unnecessarily to its power. Every function added to more widely diffused, and converts, more and more, the active and ambitious part of the public into hangerson of the government, or of some party which aims at becoming the government.
If the roads, the railways, the banks, the insurance offices, the great joint stock companies, the universities, and the public charities, were all of them branches of the government; if, in addition, the municipal corporations and local boards, with all that now devolves on them, became departments of the central administration; if the employees of all these different enterprises were appointed and paid by the government, and looked to the government for every rise in life; not all the freedom of the press and popular constitution of the legislature would make this or any other country free otherwise than in name. And the evil would be greater, the more efficiently and scientifically the administrative machinery was constructed.
