liberty. The struggle of conflicting interests in the community, which these three modes of policy represent, is yet another form of internal equilibration.
To the extent that a policy of equality is adopted, the com- munity is democratic. Political equality, equality before the law, and some approach toward equality of economic opportu- nity, are the essential elements of democracy. No sooner is democracy evolved than we see a struggle between the forces that make for absolutist, and those that make for liberal, democracy.

He may not leave his clan, his guild, his caste, his church, or his state.

The individual may go freely from state to state, from parish to parish, in search of his best economic opportunity. He may sever connection with his church to join another, or none at all. He may be a director today in a dozen corporations, and tomorrow in a dozen different ones. The goal of social evolution is a complex, flexible, liberal organization, permitting the utmost liberty and mobility to the individual, without impairing the efficiency of organization as a whole.
On the methods of sociology remark at this time must neces- sarily be brief.
Dealing as we do with highly concrete materials, we place our main reliance upon systematic induction. The experimental method of induction, however, is of little avail in the scientific study of society. Although social experimenting is at all tinaes
