Anarchism is no patent solution for all human problems, no Utopia of a perfect social order, as it has often been called, since on principle it rejects all absolute schemes and concepts. It does not believe in any absolute truth, or in definite final goals for human development, but in an unlimited perfectibility of social arrangements and human conditions which are always straining after higher forms of expression, and to which for this reason one can assign no definite terminus nor set any fixed goal.
