It was evident, however, that this moderate system, being fundamentally illogical and in contradiction with the very principles from which it proceeded, would soon become the object of serious criticism. For if the object of society and of the state is the welfare of individuals, severally considered, how is it possible to admit that this welfare can be secured by the individuals themselves only through the possibilities of such a liberal régime? The inequalities brought about both by nature and by social organizations are so numerous and so serious, that, for the greater part, individuals abandoned to themselves not only would fail to attain happiness, but would also contribute to the perpetuation of their condition of misery and dejection. The state therefore cannot limit itself to the merely negative function of the defense of liberty. It must become active, in behalf of everybody, for the welfare of the people. It must intervene, when necessary, in order to improve the material, intellectual, and moral conditions of the masses; it must find work for the unemployed, instruct and educate the people, and care for health and hygiene. For if the purpose of society and of the state is the welfare of individuals, and if it is just that these individuals themselves control the attainment of their ends, it becomes difficult to understand why Liberalism should not go the whole distance, why it should see fit to distinguish certain individuals from the rest of the mass, and why the functions of the people should be restricted to the exercise of a mere check. Therefore the state, if it exists for all, must be governed by all, and not by a small minority: if the state is for the people, sovereignty must reside in the people: if all individuals have the right to govern the state, liberty is no longer sufficient; equality must be added: and if sovereignty is vested in the people, the people must wield all sovereignty and not merely a part of it. The power to check and curb the government is not sufficient. The people must be the government. Thus, logically developed, Liberalism leads to Democracy, for Democracy contains the promises of Liberalism but oversteps its limitations in that it makes the action of the state positive, proclaims the equality of all citizens through the dogma of popular sovereignty. Democracy therefore necessarily implies a republican form of government even though at times, for reasons of expediency, it temporarily adjusts itself to a monarchical régime.
