Benedetto Croce[228] draws attention to the frequent _Intramesse didascaliche_ which mark the XXIst and following Cantos of the _Purgatorio_—notably the discourse of Statius on “generation” in _Purg._ xxv. “This poetry,” he says, “breathes throughout the spirit of the Master who knows, and desires to make clear the idea he is expounding; who stoops down towards the pupil to embrace him and lift him up towards the Truth.”[229] Beatrice, again, as Croce points out,[230] taking Virgil’s place in the journey through the skies, is like an elder sister patiently schooling her younger brother. She helps him to overcome his prejudices, to solve his problems, to conquer his doubts; now turning upon him the eye of a fond mother nursing a delirious child,[231] now laughing him out of his “childish notions,” the charm of her resplendent beauty and the illumination of her smile giving just that touch of romance to their relations that suggests the final stage of the transfiguration of the half-earthly love of the _Vita Nuova_ into something wholly celestial. But the type of this relation between Master and Pupil is most surely and most prominently drawn in that which subsists all through the first two cantiche between Virgil and Dante.[232] “Mia scuola,” Virgil calls this relation in the beautiful scene with Statius;[233] and a striking feature of this “School,” recurring in the same Canto[234] and elsewhere, is the close, intimate, easy and even playful mutual understanding between Teacher and Pupil. To this point we shall return; but first a word may be said on the sterner aspect of Education, from the pupils’ point of view. Granted that the “Primrose Path” is the only appropriate one for infant steps to toddle on; that path itself has its ups and downs—slight gradients from the adult point of view, but for the infant involving a demand for real effort and adventure. And the end of man—our human Good—lies above the zone where primroses bloom, on the heights: as Tasso sings— ... In cima all’ erto e faticoso colle Della virtù è riposto il nostro bene.[235] Let us glance, then, at what Dante has to say about the sterner side of Education—the necessary sacrifices that must be made for Liberty—and about the responsibilities of the teacher in his relation to the pupil whom he would guide up to freedom of mind and soul.
