In the Phaedrus, the Republic, the Philebus, the Parmenides, and the Sophist, we may observe the tendency of Plato to combine two or more subjects or different aspects of the same subject in a single dialogue. In the Sophist and Statesman especially we note that the discussion is partly regarded as an illustration of method, and that analogies are brought from afar which throw light on the main subject. And in his later writings generally we further remark a decline of style, and of dramatic power; the characters excite little or no interest, and the digressions are apt to overlay the main thesis; there is not the 'callida junctura' of an artistic whole. Both the serious discussions and the jests are sometimes out of place.
