Context

“Come, be a good boy, what’s her name?” But nothing could induce Marius “to talk.” They might have torn out his nails before one of the two sacred syllables of which that ineffable name, Cosette, was composed. True love is as luminous as the dawn and as silent as the tomb. Only, Courfeyrac saw this change in Marius, that his taciturnity was of the beaming order. During this sweet month of May, Marius and Cosette learned to know these immense delights. To dispute and to say you for thou, simply that they might say thou the better afterwards.” source
