Two tendencies seem to have beset the interpreters of Plato in this matter. First, they have endeavoured to hang the dialogues upon one another by the slightest threads; and have thus been led to opposite and contradictory assertions respecting their order and sequence. The mantle of Schleiermacher has descended upon his successors, who have applied his method with the most various results. The value and use of the method has been hardly, if at all, examined either by him or them. Secondly, they have extended almost indefinitely the scope of each separate dialogue; in this way they think that they have escaped all difficulties, not seeing that what they have gained in generality they have lost in truth and distinctness. Metaphysical conceptions easily pass into one another; and the simpler notions of antiquity, which we can only realize by an effort, imperceptibly blend with the more familiar theories of modern philosophers. An eye for proportion is needed (his own art of measuring) in the study of Plato, as well as of other great artists. We may hardly admit that the moral antithesis of good and pleasure, or the intellectual antithesis of knowledge and opinion, being and appearance, are never far off in a Platonic discussion. But because they are in the background, we should not bring them into the foreground, or expect to discern them equally in all the dialogues.
