But next day, the first Monday spent by the guest up here, there came another regularly recurring variation in the daily routine: the lectures, one of which Dr. Krokowski delivered every other Monday morning in the dining-room, before the entire adult population of the sanatorium, with exception of the “moribund” and those who could not understand the language. The course, Hans Castorp learned from his cousin, consisted of a series of popular-scientific lectures, under the general title: “Love as a force contributory to disease.” These instructive entertainments took place after second breakfast; it was not permissible, Joachim reiterated, to absent oneself from them⁠—or, at least, absence was frowned upon. It was thus very daring of Settembrini, who surely must have more command of the language than anyone else, not only never to appear, but to refer to the entertainment in most disparaging terms. For Hans Castorp’s part, he straightway resolved to be present, in the first place out of courtesy, but also with unconcealed curiosity as to what he should hear. Before the appointed hour, however, he did something quite perverse and ill-judged, which proved worse for him than one could possibly have guessed: he went out for a long, solitary walk.
