The power of love is represented in the “Symposium” as running through all nature and all being: at one end descending to animals and plants, and attaining to the highest vision of truth at the other. In an age when man was seeking for an expression of the world around him, the conception of love greatly affected him. One of the first distinctions of language and of mythology was that of gender; and at a later period the ancient physicist, anticipating modern science, saw, or thought that he saw, a sex in plants; there were elective affinities among the elements, marriages of earth and heaven. (Aesch. Fragment Danaïds 38.) Love became a mythic personage whom philosophy, borrowing from poetry, converted into an efficient cause of creation. The traces of the existence of love, as of number and figure, were everywhere discerned; and in the Pythagorean list of opposites male and female were ranged side by side with odd and even, finite and infinite.
But Plato seems also to be aware that there is a mystery of love in man as well as in nature, extending beyond the mere immediate relation of the sexes. He is conscious that the highest and noblest things in the world are not easily severed from the sensual desires, or may even be regarded as a spiritualized form of them. We may observe that Socrates himself is not represented as originally unimpassioned, but as one who has overcome his passions; the secret of his power over others partly lies in his passionate but self-controlled nature. In the “Phaedrus” and “Symposium” love is not merely the feeling usually so called, but the mystical contemplation of the beautiful and the good. The same passion which may wallow in the mire is capable of rising to the loftiest heights—of penetrating the inmost secret of philosophy. The highest love is the love not of a person, but of the highest and purest abstraction. This abstraction is the far-off heaven on which the eye of the mind is fixed in fond amazement. The unity of truth, the consistency of the warring elements of the world, the enthusiasm for knowledge when first beaming upon mankind, the relativity of ideas to the human mind, and of the human mind to ideas, the faith in the invisible, the adoration of the eternal nature, are all included, consciously or unconsciously, in Plato’s doctrine of love.
The successive speeches in praise of love are characteristic of the speakers, and contribute in various degrees to the final result; they are all designed to prepare the way for Socrates, who gathers up the threads anew, and skims the highest points of each of them. But they are not to be regarded as the stages of an idea, rising above one another to a climax. They are fanciful, partly facetious performances, “yet also having a certain measure of seriousness,” (197 E) which the successive speakers dedicate to the god. All of them are rhetorical and poetical rather than dialectical, but glimpses of truth appear in them. When Eryximachus says that the principles of music are simple in themselves, but confused in their application, he touches lightly upon a difficulty which has troubled the moderns as well as the ancients in music, and may be extended to the other applied sciences. That confusion begins in the concrete, was the natural feeling of a mind dwelling in the world of ideas. When Pausanias remarks that personal attachments are inimical to despots. The experience of Greek history confirms the truth of his remark. When Aristophanes declares that love is the desire of the whole, he expresses a feeling not unlike that of the German philosopher, who says that “philosophy is home sickness.” When Agathon says that no man “can be wronged of his own free will,” he is alluding playfully to a serious problem of Greek philosophy (compare Aristotle Nicomachean Ethics, v. 9). So naturally does Plato mingle jest and earnest, truth and opinion in the same work.
The characters—of Phaedrus, who has been the cause of more philosophical discussions than any other man, with the exception of Simmias the Theban (“Phaedrus” 242 B); of Aristophanes, who disguises under comic imagery a serious purpose; of Agathon, who in later life is satirized by Aristophanes in the Thesmophoriazusae, for his effeminate manners and the feeble rhythms of his verse; of Alcibiades, who is the same strange contrast of great powers and great vices, which meets us in history—are drawn to the life; and we may suppose the less-known characters of Pausanias and Eryximachus to be also true to the traditional recollection of them (compare “Phaedrus” 268 A, “Protagoras” 315 C, D; and compare “Symposium” 214 B with “Phaedrus” 227 A). We may also remark that Aristodemus is called “the little” in Xenophon’s Memorabilia, I 4 (compare “Symposium” 173 B).
The speeches have been said to follow each other in pairs: Phaedrus and Pausanias being the ethical, Eryximachus and Aristophanes the physical speakers, while in Agathon and Socrates poetry and philosophy blend together. The speech of Phaedrus is also described as the mythological, that of Pausanias as the political, that of Eryximachus
