These things, then said Serapio, seem to belong of right to the Muses, as being their particular province; for it becomes us not to fight against the gods, nor with divination to abolish providence and divinity, but to search for convincement to refel repugnant arguments; and, in the mean time, not to abandon that religious belief and persuasion which has been so long propagated among us, from father to son, for so many generations. You say very right, said I, Serapio; for we do not as yet despair of philosophy or give it over for lost, because, although formerly the ancient philosophers published their precepts and sentences in verse,—as did Orpheus, Hesiod, Parmenides, Xenophanes, Empedocles, and Thales,—yet that custom has been lately laid aside by all others except yourself. For you indeed once more have arrayed philosophy in poetic numbers, on purpose to render it more sprightly, more charming, and delightful to youth. Nor is astrology as yet become more ignoble or less valued, because Aristarchus, Timochares, Aristillus, and Hipparchus have written in prose, though formerly Eudoxus, Hesiod, and Thales wrote of that science in verse; at least if that astrology was the legitimate offspring of Thales which goes under his name. Pindar also acknowledges his dissatisfaction touching the manner of melody neglected in this time, and wonders why it should be so despised. Neither is it a thing that looks like hurtful or absurd, to enquire into the causes of these alterations. But to destroy the arts and faculties themselves because they have undergone some certain mutations, is neither just nor rational.
