practical scheme, says Oscar Wilde, is either one already in existence, or a scheme that could be carried out under the existing conditions; but it is exactly the existing conditions that one objects to, and any scheme that could accept these conditions is wrong and foolish. The true criterion of the practical, therefore, is not whether the latter can keep intact the wrong or foolish; rather is it whether the scheme has vitality enough to leave the stagnant waters of the old, and build, as well as sustain, new life.
