18. Laws of this kind have often been objected to on the strength of a one-sided view of the function of laws; the view, viz., that its only business is to prevent interference with the liberty of the individual. And this view has gained undue favour on account of the real reforms to which it has led. The laws which it has helped to get rid of were really mischievous, but mischievous for further reasons than those conceived of by the supporters of this theory. Having done its work, the theory now tends to become obstructive, because in fact advancing civilisation brings with it more and more interference with the liberty of the individual to do as he likes, and this theory affords a reason for resisting all positive reforms, all reforms which involve an action of the state in the way of promoting conditions favourable to moral life. It is one thing to say that the state in promoting these conditions must take care not to defeat its true end by narrowing the region within which the spontaneity and disinterestedness of true morality can have play; another thing to say that it has no moral end to serve at all, and that it goes beyond its province when it seeks to do more than secure the individual from violent interference by other individuals. The true ground of objection to 'paternal government' is not that it violates the 'laissez faire' principle and conceives that its office is to make people good, to promote morality, but that it rests on a misconception of morality. The real function of government being to maintain conditions of life in which morality shall be possible, and morality consisting in the disinterested performance of self-imposed duties, 'paternal government' does its best to make it impossible by narrowing the room for the self-imposition of duties and for the play of disinterested motives.
