As reading books of fiction sometimes expands the mind and enables it to grasp great practical truths, so may a study of abstract principles often enable us to comprehend the simplest forms of mechanism. Even Humboldt and Agassiz, it is said, [32] resorted sometimes to imaginative speculations as a means of enabling them to grasp new truths."Never can trust a woman as to time," he growled. There was not the faintest shadow of politeness in his manner now. "Didn't I say twelve sharp?""Well?" Lalage burst out, furiously. "Why don't you speak; what have you got to say before I put the knife into your heart?"1. The distance to which power is to be transmitted.In Rome, as well as in Greece, rationalism took the form of disbelief in divination. Here at least the Epicurean, the Academician, and, among the Stoics, the disciple of Panaetius, were all agreed. But as the sceptical movement began at a much later period in Rome than in the country where it first originated, so also did the supernaturalist reaction come later, the age of Augustus in the one corresponding very nearly with the age of Alexander in the other. Virgil and Livy are remarkable for their faith in omens; and although the latter complains of the general incredulity with which narratives of such events were received, his statements are to be taken rather as an index of what people thought in the age immediately preceding his own, than as an accurate description of contemporary opinion. Certainly nothing could be farther from the truth than to say that signs and prodigies were disregarded by the Romans under the empire. Even the cool and cautious Tacitus feels himself obliged to relate sundry marvellous incidents which seemed to accompany or to prefigure great historical catastrophes; and the more credulous Suetonius has transcribed an immense number of such incidents from the pages of older chroniclers, besides informing us of the extreme attention paid even to trifling omens by Augustus.341 Note.It does not enter into the plan of this work to study the educational and social aspects of Greek philosophy under the Roman Empire.
