He said, Culture; he said, Nature; and he failed not to add, “There is also the divine.” There is no thought in any mind, but it quickly tends to convert itself into a power, and organizes a huge instrumentality of means. Plato, lover of limits, loved the illimitable, saw the enlargement and nobility which come from truth itself, and good itself, and attempted, as if on the part of the human intellect, once for all, to do it adequate homage—homage fit for the immense soul to receive, and yet homage becoming the intellect to render. He said, then, “Our faculties run out into infinity, and return to us thence. We can define but a little way; but here is a fact which will not be skipped, and which to shut our eyes upon is suicide. All things are in a scale; and, begin where we will, ascend and ascend. All things are symbolical; and what we call results are beginnings.”
A key to the method and completeness of Plato is his twice bisected line. After he has illustrated the relation between the absolute good and true, and the forms of the intelligible world, he says:—“Let there be a line cut in two, unequal parts. Cut again each of these two parts—one representing the visible, the other the intelligible world—and these two new sections, representing the bright part and the dark part of these worlds, you will have, for one of the sections of the visible world—images, that is, both shadows and reflections; for the other section, the objects of these images—that is, plants, animals, and the works of art and nature. Then divide the intelligible world in like manner; the one section will be of opinions and hypotheses, and the other section, of truths.” To these four sections, the four operations of the soul correspond—conjecture, faith, understanding, reason. As every pool reflects the image of the sun, so every thought and thing restores us an image and creature of the supreme Good. The universe is perforated by a million channels for his activity. All things mount and mount.
All his thought has this ascension; in Phaedrus, teaching that “beauty is the most lovely of all things, exciting hilarity, and shedding desire and confidence through the universe, wherever it enters; and it enters, in some degree, into all things; but that there is another, which is as much more beautiful than beauty, as beauty is than chaos; namely, wisdom, which our wonderful organ of sight cannot reach unto, but which, could it be seen, would ravish us with its perfect reality.” He has the same regard to it as the source of excellence in works of art. “When an artificer, in the fabrication of any work, looks to that which always subsists according to the same; and, employing a model of this kind, expresses its idea and power in his work; it must follow, that his production should be beautiful. But when he beholds that which is born and dies, it will be far from beautiful.”
Thus ever: the Banquet is a teaching in the same spirit, familiar now to all the poetry, and to all the sermons of the world, that the love of the sexes is initial; and symbolizes, at a distance, the passion of the soul for that immense lake of beauty it exists to seek. This faith in the Divinity is never out of mind, and constitutes the limitation of all his dogmas. Body cannot teach wisdom;—God only. In the same mind, he constantly affirms that virtue cannot be taught; that it is not a science, but an inspiration; that the greatest goods are produced to us through mania, and are assigned to us by a divine gift.
This leads me to that central figure, which he has established in his Academy, as the organ through which every considered opinion shall be announced, and whose biography he has likewise so labored, that the historic facts are lost in the light of Plato’s mind. Socrates and Plato are the double star, which the most powerful instruments will not entirely separate. Socrates, again, in his traits and genius, is the best example of that synthesis which constitutes Plato’s extraordinary power. Socrates, a man of humble stem, but honest enough; of the commonest history; of a personal homeliness so remarkable, as to be a cause of wit in others—the rather that his broad good nature and exquisite taste for a joke invited the sally, which was sure to be paid. The players personated him on the stage; the potters copied
