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 be conducted, as those who are personally interested in it. This principle condemns the interferences, once so common, of the legislature, or the officers of government, with the ordinary processes of industry. But this part of the subject has been sufficiently enlarged upon by political economists, and is not particularly related to the principles of this Essay.
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. This is a principal, though not the sole, recommendation of jury trial (in cases not political); of free and popular local and municipal institutions; of the conduct of industrial and philanthropic enterprises by voluntary associations. 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.
