X. “Since you invite and encourage me to it yourself,” said Tubero, “let us first converse, Africanus, before the others come, about the meaning of this double sun which has been spoken of in the senate. For those who declare that they have seen two suns, are neither few in number, nor insignificant persons: so that it appears to be of less importance to doubt the fact, than to inquire into the cause of it.” “Would that we had with us our excellent Panætius,” said Scipio, “who among other objects of knowledge, was so diligent an inquirer about celestial phenomena. As to myself, Tubero—for to you I will freely declare what I think; I am not drawn in to adopt in matters of this sort, the opinions of our friend, who pronounces things which are scarcely within the reach of conjecture, to be as manifest, as if he beheld them with his eyes, or could lay his hands upon them. On which account I am accustomed to consider Socrates much wiser, who leaves the consideration of such things aside, and teaches that the phenomena about which nature may be interrogated, are either beyond the force of human reason, or irrelevant to the conduct of human affairs.” “I know not,” rejoined Tubero, “what authority there is for the fact, that Socrates rejected all discussion upon such matters, and confined himself to the moral conduct of human life. For what author is to be commended, as more ample on that head than Plato; in whose writings, in many places, it is the custom of Socrates in discussing morals, the virtues, and finally public affairs; to allude studiously to the science of numbers, to geometry, and to harmony, after the Pythagorean mode.” Scipio answered, “these things are as you say; but I dare say you have heard, Tubero, that Plato after the death of Socrates, was carried by the love of knowledge first into Egypt, afterwards into Italy and Sicily, that he might obtain an insight into the discoveries of Pythagoras. That he associated much with Archytas the Tarentine, and with Timæus of Locram. That he acquired the commentaries of Philolaus, and perceiving that the name of Pythagoras was at that time in great reputation in those places, he dedicated his time to the disciples of Pythagoras and to their opinions. But as he had loved Socrates alone, and wished to make all things conducive to his reputation, he interwove very skilfully the subtlety and humour of the Socratic style with the mysteries of Pythagoras, and with many branches of the arts.”
