[141] To trace that thread of physical colour, entwined throughout, and multiplied sometimes into large tapestried figures, is the business, the enjoyment, of the student of the Dialogues, as he reads them. For this or that special literary quality indeed we may go safely by preference to this or that particular Dialogue; to the Gorgias, for instance, for the readiest Attic wit, and a manly practical sense in the handling of philosophy; to the Charmides, for something like the effect of sculpture in modelling a person; to the Timaeus, for certain brilliant chromatic effects. Yet who that reads the Theaetetus, or the Phaedrus, or the seventh book of The Republic, can doubt Plato's gift in precisely the opposite direction; that gift of sounding by words the depths of thought, a plastic power literally, moulding to term and phrase what might have seemed in its very nature too impalpable and abstruse to lend itself, in any case, to language? He gives names to the invisible acts, processes, creations, of abstract mind, as masterly, as efficiently, as Adam himself to the visible living creations of old. As Plato speaks of them, we might say, those abstractions too become visible living creatures. We read the speculative poetry of Wordsworth, or Tennyson; and we may observe that a great metaphysical force has come into language which is by no means purely technical or scholastic; what a help such language is to the understanding, to a real hold over the things, the thoughts, the [142] mental processes, those words denote; a vocabulary to which thought freely commits itself, trained, stimulated, raised, thereby, towards a high level of abstract conception, surely to the increase of our general intellectual powers. That, of course, is largely due to Plato's successor, to Aristotle's life-long labour of analysis and definition, and to his successors the Schoolmen, with their systematic culture of a precise instrument for the registration, by the analytic intellect, of its own subtlest movements. But then, Aristotle, himself the first of the Schoolmen, had succeeded Plato, and did but formulate, as a terminology "of art," as technical language, what for Plato is still vernacular, original, personal, the product in him of an instinctive imaginative power--a sort of visual power, but causing others also to see what is matter of original intuition for him.
