Besides this sharp separation of divination from science and besides his rejection of tradition, a third creditable feature of Cicero’s book is his question: What intimate connection, what bond of natural causality can there be between the liver or heart or lung of a fat bull and the divine eternal cause of things which rules the world?[215] He refuses to believe in any extraordinary bonds of sympathy between things which, in so far as our daily experience and our knowledge of nature’s workings can inform us, have absolutely no connection. He appeals to the canons of common sense. In fact, it is generally true throughout his treatise that where he cannot disprove, he pooh-poohs superstition. On the whole Cicero’s attitude probably represents the most enlightened scepticism to be found in the ancient world. Though some of his arguments seem weak, he deserves credit for having argued at all. Against what they were pleased to call magic, men, especially during the Middle Ages, were apt to rant rather than reason. But, alas, unless we assume that the famous _Dream of Scipio_ is a purely imaginative production, that the fantastic beliefs there set forth (borrowed, no doubt, from Greek thought) are presented for dramatic purposes alone and do not represent Cicero’s actual views, we must grant that our sceptical Cicero believed in some magic after all. For the _Dream_, despite its author’s animadversions against Chaldæan astrology, speaks of Jupiter as a star wholesome and favorable to the human race, of Mars as most unfavorable.[216] Also it calls the numbers seven and eight perfect and speaks of their product as signifying the fatal year in Scipio’s career.[217] CHAPTER VII THE LAST CENTURY OF THE EMPIRE We come now to consider some indications of the intermixture of magic with learning in the last century of the Roman Empire, the border-time of the Middle Ages. It was a time when interest in science was slight and when the ability to use florid rhetoric was apparently the chief aim of those who assumed to be the highest intellectual class. What science there was was largely permeated with magic, as a glance at a few men of intellectual prominence then will illustrate.
