Liberalismo e democracia

Government by a handful of people - and the rulers are always as much in the minority as against those ruled as the producers of shoes are as against the consumers of shoes - depends on the consent of the governed, i.e., on their acceptance of the existing administration. They may see it only as the lesser evil, or as an unavoidable evil, yet they must be of the opinion that a change in the existing, situation would have no purpose. But once the majority of the governed becomes convinced that it is necessary and possible to change the form of government and to replace the old regime and the old personnel with a new regime and new personnel, the days of the former are numbered. The majority will have the power to carry out its wishes by force even against the will of the old regime. In the long run no government can maintain itself in power if it does not have public opinion behind it, i.e., if those governed are not convinced that the government is good. The force to which the government resorts in order to make refractory spirits compliant can be successfully applied only as long as the majority does not stand solidly in opposition.

There is, therefore, in every form of polity a means for making the government at least ultimately dependent on the will of the governed, viz, civil war, revolution, insurrection. But it is just this expedient that liberalism wants to avoid. There can be no lasting economic improvement if the peaceful course of affairs is continually interrupted by internal struggles.

Here is where the social function performed by democracy finds its point of application. Democracy is that form of political constitution which makes possible the adaptation of the government to the wishes of the governed without violent struggles. If in a democratic state the government is no longer being conducted as the majority of the population would have it, no civil war is necessary to put into office those who are willing to work to suit the majority. By means of elections and parliamentary arrangements, the change of government is executed smoothly and without friction, violence, or bloodshed.
