From that day forth, Balthazar made no attempt to disguise the weariness and the depression that assailed him. In the mornings, after the family breakfast, he played for awhile in the parlor with little Jean, and talked to his daughters, who were busy with their sewing, or embroidery or lace-work; but he soon wearied of the play and of the talk, and seemed at last to get through with them as a duty. When his wife came down again after dressing, she always found him sitting in an easy-chair looking blankly at Marguerite and Felicie, quite undisturbed by the rattle of their bobbins. When the newspaper was brought in, he read it slowly like a retired merchant at a loss how to kill the time. Then he would get up, look at the sky through the window panes, go back to his chair and mend the fire drearily, as though he were deprived of all consciousness of his own movements by the tyranny of ideas. Madame Claes keenly regretted her defects of education and memory. It was difficult for her to sustain an interesting conversation for any length of time; perhaps this is always difficult between two persons who have said everything to each other, and are forced to seek for subjects of interest outside the life of the heart, or the life of material existence. The life of the heart has its own moments of expansion which need some stimulus to bring them forth; discussions of material life cannot long occupy superior minds accustomed to decide promptly; and the mere gossip of society is intolerable to loving natures. Consequently, two isolated beings who know each other thoroughly ought to seek their enjoyments in the higher regions of thought; for it is impossible to satisfy with paltry things the immensity of the relation between them. Moreover, when a man has accustomed himself to deal with great subjects, he becomes unamusable, unless he preserves in the depths of his heart a certain guileless simplicity and unconstraint which often make great geniuses such charming children; but the childhood of the heart is a rare human phenomenon among those whose mission it is to see all, know all, and comprehend all.
