"I don't know what to say, my son," replied. Don Diego; "all I can tell thee is that I have seen him act the acts of the greatest madman in the world, and heard him make observations so sensible that they efface and undo all he does; do thou talk to him and feel the pulse of his wits, and as thou art shrewd, form the most reasonable conclusion thou canst as to his wisdom or folly; though, to tell the truth, I am more inclined to take him to be mad than sane."
-No sé lo que te diga, hijo -respondió don Diego-; sólo te sabré decir que le he visto hacer cosas del mayor loco del mundo, y decir razones tan discretas que borran y deshacen sus hechos: háblale tú, y toma el pulso a lo que sabe, y, pues eres discreto, juzga de su discreción o tontería lo que más puesto en razón estuviere; aunque, para decir verdad, antes le tengo por loco que por cuerdo.
