§31.30.1ἐγὼ δὲ πλείω πεποίημαι λόγον ὑπὲρ τῆς Σκιπίωνος αἱρέσεως ἐκ τῆς πρώτης ἡλικίας, ἡδεῖαν μὲν ὑπολαμβάνων εἶναι τοῖς πρεσβυτέροις, ὠφέλιμον δὲ τοῖς νέοις τὴν τοιαύτην ἱστορίαν, §31.30.2μάλιστα δὲ βουλόμενος πίστιν παρασκευάζειν τοῖς λέγεσθαι μέλλουσιν ἐν ταῖς ἑξῆς βύβλοις περὶ αὐτοῦ πρὸς τὸ μήτε διαπορεῖν τοὺς ἀκούοντας διὰ τὸ παράδοξά τινα φανήσεσθαι τῶν συμβαινόντων μετὰ ταῦτα περὶ αὐτόν, §31.30.3μήτʼ ἀφαιρουμένους τἀνδρὸς τὰ κατὰ λόγον γεγονότα κατορθώματα τῇ τύχῃ προσάπτειν, ἀγνοοῦντας τὰς αἰτίας, ἐξ ὧν ἕκαστα συνέβη γενέσθαι, πλὴν τελέως ὀλίγων, ἃ δεῖ μόνα προσάπτειν τῇ τύχῃ καὶ ταὐτομάτῳ.
But I have made a longer account of Scipio's choice of life from his early youth, considering that such history is pleasant to the older and useful to the younger, and especially because I wished to prepare belief in what is going to be said about him in the following books, so that the listeners may neither be perplexed because some of the events that happened to him after this will appear marvelous, nor, being ignorant of the causes from which each event happened to come about, deprive the man of his successes achieved in accordance with reason and attribute them to fortune, except for a very few, which alone must be attributed to fortune and chance.
§31.30.4ταῦτα μὲν οὖν ἐπὶ τοσοῦτον ἡμεῖς διεληλυθότες κατὰ τὴν παρέκβασιν αὖθις ἐπάνιμεν ἐπὶ τὴν ἐκτροπὴν τῆς ὑποκειμένης διηγήσεως.
Therefore, having gone through these matters to this extent in our digression, we shall return again to the departure point of our present narrative.
