Moral Letters to Lucilius Section 17

Alexander Macedonum rex discere geometriam coeperat, infelix, sciturus, quam pusilla terra esset, ex qua minimum occupaverat. Ita dico: infelix ob hoc, quod intellegere debebat falsum se gerere cognomen. Quis enim esse magnus in pusillo potest? Erant illa, quae tradebantur, suptilia et diligenti intentione discenda, non quae perciperet vesanus homo et trans oceanum cogitationes suas mittens. Facilia, inquit, me doce. Cui praeceptor ista, inquit, omnibus eadem sunt, aeque difficilia.

Alexandre, roi de Macédoine, commençait l’étude de la géométrie ; le malheureux !

Alexander, king of Macedon, began to study geometry; unhappy man, because he would thereby learn how puny was that earth of which he had seized but a fraction! Unhappy man, I repeat, because he was bound to understand that he was bearing a false title. For who can be “great” in that which is puny? The lessons which were being taught him were intricate and could be learned only by assiduous application; they were not the kind to be comprehended by a madman, who let his thoughts range beyond the ocean. “Teach me something easy!” he cries; but his teacher answers: “These things are the same for all, as hard for one as for another.”
