First of all, poetry is a tool of literary concision.
And since you have to have concision, you don't have time to explain it.
A brilliant melodist, colourist and miniaturist, Bizet instinctively composed with the dramatic concision of his heroes Beethoven, Mozart and Mendelssohn.
Sainte-Beuve's criticism is almost identical with Gibbon's own; but though he finds that " la lecture en est assez difficile et parfois obscure, la liaison des idees echappe souvent par trop de concision et par le desir qu'a eu le jeune auteur d'y faire entrer, d'y condenser la plupart de ses notes," he adds, y a, chemin faisant, des vues neuves et qui sentent l'historien."
Such superb self-confidence can accomplish much, and it undoubtedly helped to form Fustel's talent and to give to his style that admirable concision which subjugates even when it fails to convince; but a student instinctively distrusts an historian who settles the most controverted problems with such impassioned assurance.
